- engine battery should hook directly to the starter
- not good to crank thru the cut-off switch (370 amp draw)
- ground from the battery to the engine
- ground from the battery to the frame




Thanks Gene. Do you mean that the hot lead should run directly to the starter then back to the starter solenoid? Currently it runs to the solenoid and from there to the battery.

Is the #4 wire gauge OK or do I need to go larger?

Is there any need for a battery disconnect?

I was speaking to Ken Henderson this morning and he questions the isolator. Do you have a link to the isolator testing procedure? I haven't run across it yet. I'm also going to check and make sure there is an APC on the alternator. If not, I'll be ordering one today.

George, the coach battery is a marine deep draw so I'll probably just buy a new battery for the engine.
