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.

So I did as you said to and disconnected the batteries and took voltage readings after I did that. So, the two orange posts read between 9.4-11.5 without the batteries hooked up. Then the wires going into the charge board, 4/5 read the same 9.4-11.5. Then the top wire, which ended up being white, read 22.8. I have the picture attached that show the readings on the relay that switches power over as well. Then hooked the batteries back up and they read the same as before.
