Battery Solenoid or Starter
Port engine battery bank indicates 32 plus volts. It won't turn over the motor. Motor starts when the parallel switch is engaged to use starboard battery bank. Set up is original.
Where should I start trouble shooting this?
Thanks for your help.

Re: Battery Solenoid or Starter
Have someone turn the key while their doing that you test the volts in the battery. Do you really have enough juice to turn the motor over. That happened to me. Had to buy a new starting battery. 2 dead cells. Showed power until you turn the motor over.
Re: Battery Solenoid or Starter
Check all the cells with a hydrometer. It's probably showing a surface charge but has no reserve.
How old are the batteries?
Re: Battery Solenoid or Starter
Start with the voltage test on the battery. I approached it from the starter cable end and could have saved a lot of time and energy.

No don't buy that crap.
Get a real one.
It needs a thermometer on it too.

Re: Battery Solenoid or Starter
Given that it will hit with the parallel switch, could be a few things, batteries, cabling, Cole Hersey Solinoid in the battery isolator box, or battery isolator switch itself. Mine is a 1987 model, and all of the battery isolator selector switches have failed over the last few years.. Lot of brittle plastic in those switches and when they fail, that battery bank is out of the loop.

I've got a few from NAPA. I leave on in the engineroom of my boat so I don't need to look for it.

Check the battery switches. The plastic cracks and releases some of the spring tension. Then the switch can't deliver enough amps to spin the diesel. Steve
