A friend has the above engine
and just told me that when the yard disconnects the negative, start battery
cable, the engine
starts cranking. Don't know if the pos. cable was still on.
I haven't witnessed this but the owner says it has happened before.
It has 2 house batteries
on an A/B switch and an independent genset battery
I will get more info in a few days. I know it's weird but any guess's what's going on.
