Understanding better how the transformer works Here's a few more things to check. Start with the easy things. There is a yellow button on the general purpose breaker. I'm wondering if it's a GFCI. If you plug into shore power and press that yellow button does anything suddenly start working?

On the front of the panel is a charge sentinel light. When plugged into shore power does that light do anything? Does the light come on, on and blink fast, on and blink slow, or stay off?

In this picture are three arrows.

What color is the wire that the green arrow is pointing to? Where does that wire after it goes through the hole on the left?

The red and blue arrows are pointing to wire connections at the back of the charge sentinel light.

If you plug in shore power how many volts are on the red arrow?

While still plugged in to shore power how many volts are on the blue arrow?

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.

The OP has a 734Q series unit. Here are 3 PD links for it from here:

I tried the yellow button and nothing happened. Then I checked the light and it wasn't lit up or anything.

So the wire is just a copper wire that ends on a board with about 8 other wires on it. Then the Red and blue wire both read 12.57 plugged in

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.

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.

So I Went out and tested voltage again and found this While plugged into shore power. I thought it was weird and then after a few it jumped up to the 14.28 on one side that it was before, and then it stopped and never went back up to that number and would lie somewhere between .15-.5. That definitely doesn't seem normal to me. Then after it dropped I tested it again and the center post on the battery side shows a negative like something is crossed or something if that makes sense. Its only done that when the voltage dropped, but all 4 other posts show a positive charge. I haven't messed with any of the wiring in there and it doesn't look like anyone has. So am I crazy?

No not yet , you have to have a thread go 8 pages to qualify for that. Be patient , we will get you there. [emoticon]
