Re: Engine Battery cable to starter motor to be replaced - looking for experience
toggle quoted messageShow quoted text
There is a single non-spliced cable from the battery switches for both positive and negative wires. There is a single start battery.
It is not the wire, unless you have cut or damaged one and that is unlikely.
If the battery is good, don't you wonder why jumping the battery starts the engine?
I would remove one battery from the house bank and replace the start battery. If the engine starts, maybe it's the start battery.
Also, you didn't mention the Onan. Does it start without the Yanmar running? If it does, then it is probably not the start battery, but could be bad connections at the main switch, the switch itself, the battery, or at the starter. If the connections are suspected, clean them and treat with CorrosionX.
Get back to me after you have some answers.
