RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, OK I guess I can assume the replacement charger board did not fix the problem. Your system may have only one SCR or maybe two SCRs wired in parallel. A SCR is a 3 terminal device, an input terminal (anode), an output terminal (cathode) and a gate terminal. When connected to shoreline power, measure the DC voltage to ground on all three SCR terminals. The output terminal should be the same as your house battery voltage, 12.48 volts per a previous measurement you made. The voltage at the input terminal should be I believe around 18 volts, the same as the output voltage from the transformer module you previously measured. The voltage on the gate terminal will tell the story. If it is more than 1.0 volt higher than the SCR’s output terminal, then that or both SCRs are toast.

RE: Best house battery?

My opinion on a lot of these types of questions is that if there truly was a one and only one best house battery, it would be the only one left on the market.

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, OK, look at the schematic on page 20 of the maintenance manual. You will notice the SCR in the upper left corner of the schematic. The SCR acts like an electronic on/off switch. How the system works is that the battery charger PC board monitors the charge level of the house battery(s) by inputting the current battery voltage level onto the red wire going into the board. The board analyzes this voltage level and determines if further charging of the battery(s) is necessary, If so, the board sends a signal to the SCR's gate terminal via the green wire shown which then turns on the SCR connecting the output of the DC voltage output of the transformer module via the blue wire shown into the SCR and since the SCR is now turned on the SCR now conducts that DC voltage to the output terminal of the SCR which connects to the battery9s) via the orange wire. Actually, the SCR is never fully turned off. The charge board varies the signal to the SCR gate via the green wire on a pulse basis with the turn on pulse being longer when the battery(s) are heavy discharged to a turn on pulse being shorter when the batter(s) are fully charged and only requiring a low level maintenance charge level. If this SCR was destroyed when the former owner connected up the battery(s) reversed polarity, of course the charge board would be trying to turn on the SCR to try and make it conduct a charge current to the battery(s) to no avail.

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, well your replacement battery charger PC board is on the way to you. Sure hope this fixes the no charging problem. If not the only other thing that I can think of is a failure of the S.C.R. as shown on pages 3, 17 & 20 of the Service Manual. I can believe that this component may have been destroyed if as you said the former owner of your rig connected up the house battery(s) reversed polarity. The SCR is mounted in a heat sink as shown on page 17 in the transformer module. Leads to it would have to be unsoldered and then the part would then have to be unbolted to remove it. Then hopefully the SCR has brand and P/N on it in order to purchase a replacement.

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, Andy with PD sent me an email this morning and unfortunately he had already shipped the charger board to me. So, send me your real name and shipping address and I will reship it to you after I receive it. You can contact me via PM (private mail) with that info if you prefer.

BrocNeal, Just for my own interest I contacted Progressive Dynamics about availability of repair of battery charger PC boards or replacements. I have copied the email I sent and the email I got back from Andy at the factory below. -----Original Message----- From: William R Hemme Sent: Thursday, July 23, 2020 2:03 PM To: [email protected] Subject: PD734Q Repair Does Progressive Dynamics still repair or have replacement battery charger PC boards for the PD734Q RV power center? Bill Hemme -----Return Message----- Andy Giesen RE: PD734Q Repair To: Bill Hemme Hello, We do not repair the charger boards. I found a 6 pin charger board in our old inventory. I am not even positive it works as I have no way of testing now. It should work though. I am happy send it out to you at no charge I will put it in the mail and send it to the address on Elmwood dr. Let me know how it works for you. Andy I emailed Andy back to not send the board to me and I would contact you about it. Please contact Andy at his email address [email protected] if you want to receive this board free of charge. This of course assumes that your board is the model with a connector that has slots for 6 pins. Best I can tell from your photos is that describes your board.

RE: Generator/Shore Power Work, Battery Power Doesn't

Since I am not there to actually trace out each wire connection to the battery charger PC board, I can’t tell by looking at your photos which are power input wires and which are power output wires to the board. On one of the manual pages it references sending in the board for factory repair at $22.00 plus return freight charges. Since this manual is rather dated, I would contact Progressive Dynamics to see if they still repair this board or have replacements and the current costs. It appears that the board can be removed by unplugging the 6-pin connector and removing a couple of mounting screws.

RE: Generator/Shore Power Work, Battery Power Doesn't

Well that means to me if your voltmeter connections were correct that the 22 vdc coming into the battery charger PC board would appear to be somewhat normal so the transformer module seems to be working OK. However the 9.4 to 11.5 vdc coming out of the charger board is way too low to cause any charge to your batteries. Also if there was any significant battery charging current coming out of the charger board, that LED indicator light as shown in the schematic on page 20 of the manual would be illuminated which it isn’t. My conclusion again is that the charger PC board is toast.

RE: Generator/Shore Power Work, Battery Power Doesn't

So mine doesnt have a blue wire going to the charge board. But I don't have 16 going into it anywhere. Then the 2 orangeish wires I have going anywhere go to a circuit breaker and I have 12.48 going to both posts on that. Looking at the manual, I should have a light doing something if the charger was working. And I have no light whatsoever no matter what it's doing. So I dont know if that means the charger is bad and that's my problem with my lights or what. BrocNeal, Both pages 3 and 20 of the service manual show a blue wire going into the battery charger PC board. Why you don't or can't find that blue wire is a puzzle. However, at this point I believe the 14.28 vdc you are measuring on the orange wires on both terminals of the Auto Breaker is actually the voltage coming from your batteries and not the voltage being generated by the battery charging circuit. So, do this next. Temporarily disconnect all leads going to the positive terminals of of your batteries. Then connect up to shoreline power (you won't now be abe to start your generator). Then measure the voltage on the two orange wires and post what it is. Then please find the blue wire (or what ever the color is in your system) that connects the blue wire input to the battery charger pc board as shown on page 20 of the manual. Then measure that voltage going into the battery charger board. If you have significant voltage there but no voltage on the orange wires then that tells me that your battery charger pc board is bad and you need to find a replacement board.

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, Things to check now that you have the service manual to reference. 1) Using a voltmeter against ground, check the voltage on the blue wire going to the battery charger board when either plugged into shoreline power or with generator running. If it reads around +16 vdc or so that is good showing that the dc output from the transformer module is good. 2) Then check for dc voltage on the two orange wires going to the Auto Breaker. You should have around +14 vdc on both orange leads. If no dc voltage on either orange lead, then the battery charger pc board is bad an must be replaced, If dc voltage exists on one orange lead but not the other, than the Auto Breaker is open and must be replaced.

RE: Generator/Shore Power Work, Battery Power Doesn't

OK, I have located the Progressive Dynamics Service Manual for your PD734Q Power Center and you can download it by clicking on the following link: Service Manual Please read the section on page 3: How the converter works. Also note that there is a separate Transformer Module as shown on page 17. Your unit has option R which includes the relay rather than option F which incorporates a manual switch. The document contains a lot of trouble shooting information that may help you isolate the problem.

RE: Generator/Shore Power Work, Battery Power Doesn't

If you force the relay contacts together with additional manual force and everything starts working then there is your problem. The relay contacts are dirty and must be cleaned and dressed with a relay file. That should restore the proper operation of that relay.

RE: Generator/Shore Power Work, Battery Power Doesn't

Well if that was true then when with shoreline power or generator running then both sets of lights, AC powered and DC powered should both be on. I think this problem needs to be troubleshot by an experienced RV technician at a RV shop such as Camping World or similar.

RE: Generator/Shore Power Work, Battery Power Doesn't

Well it means that you have a really weird problem that most likely can’t be solved on this forum. I can’t believe it is somehow related to a defective charger/converter. To prove that your charger/converter is working properly do this test. Measure your battery voltage without generator or shoreline power. I think you said it was 12.4 vdc. Then on shore line or generator power, the battery voltage should increase to at least 13.8 vdc indicating that your batteries are being charged. If no change then your charger/converter is defective or AC power to it disconnected or associated circuit breaker tripped? Also most motorhomes are equipped with a house battery master ON/OFF switch. Make sure that switch is ON.

RE: Generator/Shore Power Work, Battery Power Doesn't

OK. In all motorhomes that I am familiar with the DC operated lights are hardwired to the battery thru a fuse marked LIGHTS in your fuse panel. That connection is not interrupted while on generator or shoreline power or not. So what you describe seems unlikely. Now your water pump is DC powered like your lights. Does your water pump work in all cases like it should?

RE: Generator/Shore Power Work, Battery Power Doesn't

Now when I use the generator or shorepower no AC or appliances. But if i plug into shore power i have everything but lights, but the appliances and AC work. Would that indicate the converter is bad? You are confusing above. First you say when I use the generator or shorepower there is no A/C or appliances working. Then in your next sentence you say if you plug into shore power then you have everything’s except lights. Please explain???

RE: I'm buying one (surprise)

Generator won’t start, water won’t flow, radio doesn’t work, tires are shot. What other signs do you need that this motorhome has had very poor care. Unless owner fixes all problems before you buy it, I would walk.

RE: BORN FREE's Kim Olson still in the RV business?

I am 79 years old and own a 2002 Born Free 26’ RSB coach. Probably my last motorhome since what I have still works well. If something needs fixing I just spend the money to fix it. If I ever wanted to upgrade, I would seriously consider a Lazy Daze. This coach is only available factory direct just like the Born Free was for many years.

RE: BORN FREE's Kim Olson still in the RV business?

Kim Olson like all other former Born Free employees have moved on and found other jobs. The original factory is not producing any motor homes but the last I knew, pontoons for pontoon boats were being made there. I live 75 miles from that factory location and travel by it occasionally in my travels around the state of Iowa. The last time I had contact with Kim, he told me that he was considering starting up a website to source and sell common Born Free replacement parts and when and if he did that, he would advertise this on the Born Free Leap’n Lions RV Club’s website. So far he has not done this and so far it looks unlikely. The club’s website’s forum offers sources of some parts in both the Coach Modifications and Technical Library sections.
