RE: Trimetric B+ wire for two 6 V
I think I already know the answer to this but it never hurts to ask just to make sure, especially since I'm voltage-challenged.
In the instruction packet, the factory does not show where to connect the B1+ wire in a two-6volt combination. My guess is at the positive terminal A since you get 12.7+volts between there and the ground side of the shunt. At terminal B it's only 6 Volts. The other 3 Trimetric wires are connected at the shunt according to the factory diagram.
http://img.photobucket.com/albums/v305/JerryCrawford/12voltwiring-1.jpg
Terminal A is also where I should connect the POS wire for the electric jacks and the charging wire from the truck pigtail through the converter.
Have I got it right?
Yes...You should only have one wire on that battery side of the shunt. The one that goes to the battery!!!
You should put a small amp fuse right at the battery, on the + wire going to your trimetric!!! The smaller the better. .5amps would be great but 1 or 2 would be ok too. You don't want that little tiny wire going to your trimet ever to short to ground with out a fuse!!!!!

RE: fridge warms when driving
I had the same problem a few years ago. I added baffles per RVMobile.com There are a few of us on rv.net tc forum that have preformed this modification...
Everyone should bookmark his website....He rebuilds cooling units, has parts and excellent tech notes!!
Here's the link for the modification description and pictures.

RE: Looking for Cheap Digital Panel Meter...
Got mine off ebay for about $20. They are blue numbers, self powered (from the incoming line). I put switches on them as one person said, they are bright at night. Top is 120 V (I wasn't plugged in when I took the pic) and bottom is battery.

Nice meters....Is the 120 an Ac meter or did you do what I did and build a circut to do the 120?
If your measuring a shunt, where the voltage is in going to be under 100mv or 500mv do they have one that will run on a separate source voltage???
Guess the real question is what is the make of the meters. I've looked quite a bit and not seen a blue light special....hee hee.
Although my meters are not back lit I don't mind but need a separate supply to operate. I have a small 12vdc battery 1.5 AH Security system type that gets charged every time I'm plugged in. That is my source supply voltage for my meter panel....I also have the 9vdc battery for momentary operation or if something happened to my small 12vdc battery.
Each meter pulls about 1 ma...

RE: Looking for Cheap Digital Panel Meter...
The referenced LCD meters that run on 9vdc are highly un-reliable and are prone to drift with temperature change...They are susceptible to static electricity, even external of your RV if you have solar and are monitoring 12vdc...
If you decide to use them...make sure that when you mount them in a panel you make the cutout large enough that it does not in any way stress the frame of the meter. If you don't you will have intermittent connection problems with the display. I opted not to use the lock tabs that are on the meter frame. I put them in place and them hot glued in the corners.
You may go through 2 or more before you find one that will not drift

RE: Looking for Cheap Digital Panel Meter...
DCR021205. Simple reference design so no banging my head in vain.
Are you sure about that? ;-)
It doesn't look like it will work. The meters that have been discussed require min 6V. This dc/dc outputs only 5V. The meter could be pretty dim if it works at all. The TI web page lists Vin(Max) = 13.2V. The smoke will be coming out before you know it. You *may* be banging your head about now. ;-)

RE: aeriel booster
Just in case you mean leaving the RV plugged into electricity and being gone a long while please turn those tv amps off. Batteries go dry, the ac ripple goes up, and then the darn things can go into an oscillation that causes harmful interference to public safety radios.
Now I would believe that if it were one of the old magnetek converters but with switcher technology converters that most of us have there's no ripple. I have bench tested several converters for there standalone operation....Clean 12 vdc power...

RE: aeriel booster
Sundowners, you are talking about your tv signal/antenna booster?
Is you rig set up for your UK 240vac system? We call "Shore Power".
Does your booster run on 12 volts dc? Most of ours here are Winegards and do run on 12vdc. If your's is 12vdc then your ok.
If your rig is setup for 240vac and your booster is an AC type you should check the unit to make sure it will run on 240.
Is your TV 240 or combo voltage 110/240?
Hope this helps.

RE: Need Metal TC Cover Pictures
That's exactly what I need! Too bad I can't get them here in Washington State.
Geezzzzzzz I went to the website and the whole Westcoast is not listed.
I emailed them and asked what's up!!!!
They are the company that sells carports that you see on the side of the road all over the place.... $875 for a basic 12X20X9 carport.
If they are not responsive here is company I dealt with to get a patio carport....I got a 18X20X10 for $1200 including tax and shipping to the nearest Fedex Depot...

Mine was based on the Boxed eves style:

When I ordered mine the install team came over 200 miles to do mine. It took them about 2 hrs to assy the dang thing....
$2200 for everything. I did the concrete, water and 110.
Mine is 11 ft high...I should have done 12. I had to remove one gable panel to get the camper in....
Hope this helps,

I would, if I were to do it again make the roof panels run on the slope instead of across the flat. Tje rain water would run off the sides rather than the ends.

RE: Fuel-cell technology arrives for RVs
Just like everything else that takes a lot of capital to develop and market, the price will come down.
Remember memory....A 256K one bit chip was 10 bucks or more back in the 70's...Now you can get a Gig X 8 bits for under $25.

Popkorn, good decision to do it out of the battery compartment!!!
Your right about the battery compartment...quite small. Wish it was just a bit taller...then I could use group 27's instead of 24's...
What's your plans for battery placement and type?

RE: SF Series Furnaces
I thought most RVs usually came with the Atwood version of that furnace? Suburban and Atwood have a very similar looking unit, however you are right about the amp usage, that model hogs it at 8.5 amps for the 30,000 btu and under units, the 35,000 used 9.4 amps and the 42,000 uses 11.5.
Right on JoeChiOhki, that's why I said, "like this" and his question was, "Does anyone have any personal experience with this furnace? What type of things should be done yearly to keep it running good?" so I gave him a little bit about maintenance and what the difference is between his and the type most campers have that the electronics etc is accessible from the outside.

RE: SF Series Furnaces
We have a SF 35,000 BTUH Series Furnaces in our home.
Does anyone have any personal experience with this furnace?
What type of things should be done yearly to keep it running good?
Many of us TC'ers have the 25,000-35,000 BTU furnace like this:
http://www.pplmotorhomes.com/parts/rv-furnaces/rv-furnace-atwood-excalibur.jpg
Let me tell ya, the dang thing is noisy!!!! The noise is the blower, it sounds like a 747 jet engine ferchristsake....We just use it to get the edge off while we fire up our Wave-3....
Some TC's that are newer have the 2 speed fan which is nice.
But as Sleepy says, "The dang furnace is an AMPAHOLIC" as it pulls 6-8 amps/hr when running...So with a duty cycle of 4 times an hour for 5 min that would be 20 min each hour....so every 3 hrs you burn through 6-8ah...That doesn't sound like much but if you leave it on 24 hrs when boondocking that would be 48ah for 6 amps and 64ah for 8amps draw.
You can do the math....for btu's.....about 92,000btu's per gallon...
The sucker does burn up the LP.
This type is easy to work on and has access from the outside.
Maintenance is just making sure battery connections are tight and that no insects/wasps are trying to live in the heat exchange vents and inside the cabinet. Not much else to do except to become familiar with the unit and it's operation so you can work on it. I printed out the wiring/diagrams so I have it for my unit.
On yours it looks like you can not get at various things like we can....

RE: Progressive 9245 + Interstate AGM batteries
Bottom line, this converter will never output max current. It's a poor choice if you're using a generator. Sal
Now you tell me :B. I have had one problem after the other with batteries on this snowbird trip. We stay in dry camp for 3-4 weeks at a time and then on hookups for 2. I'm only seeing about 13.5V at the batteries on boost with the 9245 and batteries don't charge enough to get a SG reading even if I leave the gen on for 12 hours. It's the second set of Grp 29s to do this, both sets no more than 4 weeks old. Are you saying the 9245 will not charge sufficiently in the relatively few hours that one can run a generator? If so, what charger will? Thanks! Steve
I would do the reset I wrote about in a couple of posts ago....
It's a quick easy test to see if in fact your PD will do 14.4....
The batteries do not need to be discharged...
Just turn off shore power, turn off all 12 vdc items...disconnect the battery (battery cutoff switch), wait about 20 seconds, hook the battery (s) back up, and restore shore power or run the genny....watch the voltage!!!!
If you have to remove a lead on the battery, when you put it back on you will see an electrical arc/snap....not to worry...that's the electronics in the converter charging up.
If you think your batteries are full but they have not seen the 14.4 for a while the voltage may not be at 14.4, maybe around 13.9....The voltage will climb. You should see it get to 14.4 in an hour or so depending on your battery bank size.

RE: Progressive 9245 + Interstate AGM batteries
Jim, the formula should be correct. The 45A and 60A converters have different efficiencies. If the 60A converter has an efficiency of 81.6% (not 85%) then we get:
Pout = 1000W * 81.6% = 816 W
Vout = Pout / Imax = 816W / 60A = 13.6 V
Hey, Ohms Law HAS to work!
Sal
So using the formula for the PD9260....
Pin=1000 W X 85%(efficiency) =850 w Pout
850w /60=14.2V So a major discrepancy..
But the spec for max of the PD9260 is 13.6 or....12.6 depending on which spec you use....See the link above...
I can see 55-60 amps come out of the PD...but as you say only for a very short time,,,,and the voltage is in the low 13's.
I still like the PD unit for it's flexibility..
Jim
Wow, I missed that in the specs.....80% efficient.....I was just assuming 85%....
So I wonder what Progressive dynamics means by, " full load is >12.6vdc??? I guess just that, full load is will be greater than 12.6.
