Why doesn't the PC have a solenoid battery isolator like these? https://www.powerstream.com/battery-isolator.htm
That connects the house batteries for charging to the engine battery and the alternator once the engine battery is fully charged, but it also has a connection point that goes to the momentary emergency switch inside so you can manually make the connection to start the engine from the house battery. The cables to the relay would be heavy battery cables so there is plenty of current for both charging and emergency starting.
I thought the emergency switch on the PC is the same but it's the light wire that only charges while you hold it. I can understand why the fuse on it slows if you try to start the engine while holding the switch as you would do with an isolator.
I already got stranded when the engine battery died because I left the lights on while camped. In that case the existing switch didn't help.
Maybe I'll install one of the Powerstream isolators.
