I had an unusual electrical issue in my 2007 Great West on a 2006 Chassis. After sitting for some time, the starter battery was very dead. I attempted to use my boost switch that provides 12V from the house batteries to the original solenoid connecting the house battery circuit to the starter battery circuit. I have installed a Sterling B2B to charge my LiFePO4 from the engine. Both are not used at the same time.
I turned on the boost switch but no current was flowing. All of the electrical devices on the original house battery panel were not working. The B2B, solar charge controllers and inverter that I wired up were all working fine. I charged the starter battery, not an easy feat as the voltage was so low the charger had to be started on the 6V position, then switched to 12V after a while. After the battery was charged, the rear appliances and the air ride compressor still would not work.
I came back a couple days later, and tried to see what was working and what wasn't. As part of that, I ran the generator, part of the original installation. After that, everything was working. I did no repairs.
The original 12V house system is somewhat of a mystery. I know what I added, but don't have any info on the original system. For example, there is a resettable breaker under the vehicle and I have no idea what it does. It is quite rusty. The wiring is substandard, thinner than it should be and with poor connections, but I don't see any specific issues. In the past, a bad house water pump caused a huge voltage drop on the wires without blowing a fuse, so I know the wires are too small. With everything working, there is nothing to troubleshoot now.
Does anyone have any suggestions as to what might have happened. Does anyone know more about what Great West installed originally?
