House batteries not charging from chassis (SOLVED)
2016 Sunseeker 2250S (Forest River) on Chevy chassis:
Last year all was fine - the house batteries were being charged from the chassis any time we were underway.
We have a 2 1/2 week run coming up shortly, and I'd like to fix this issue before we depart...
This year, we've had two trips, and while I don't know if this was an issue on the first run over a weekend but we noted the following on our recent 5 day run:
We boondocked the first 3 nights, and noticed the chassis battery voltage was running in the 12.2 to 12.0 range where it should have been 12.8 to 12.4.
I ran some tests and found the batteries were not being charged while underway - the chassis was running at 13.8 to 13.4, yet the house batteries never increased.
Only when we plugged into shore power did they come up to the (charging) values in the 13.* ranges, then standing charge after several hours off shore power was 12.8.
Something is wrong.
The 2250S Sunseeker has a Precision Circuits 00-10033-300 FR BCC, of which I can find no documentation or troubleshooting information.
Even the relay was not clicking when pressing the emergency start switch located on the base of the drivers seat - we found that a fuse had not been plugged into the correct socket (apparently during assembly). Once a fuse was installed in the proper circuit - we now have a functioning emergency start.
The circuit breaker under the hood is not tripped - we have 12v from the chassis at the BCC. When pressing the emergency start - the house voltage jumps up & matches the chassis.
There seems to be no voltage on J12 labeled "Ignition In" while the engine is running, even after several minutes.
We tried jumping power to J12 but the system shut down. I had installed a volt meter last year in the convenience center so we could monitor the actual voltage - it and all other 12v items disconnected. Interesting.
There has to be an ignition in to tell the BCC to connect the two systems...
Here's the panel:
If you experienced this issue, what did you do to correct it?
I've posted this note on forestriverforums.com - Sunseeker as well to see if I get assistance there - if so, I'll report back here on results.
