88fc where is the AT solenoid

RE: 88fc where is the AT solenoid
Hi Curt, I think the AT solenoid powers or unpowers different appliances and processes on each unit model year. I was looking for a wire diagram for this 88fc to see just what it powers. Something tells me that it is partialy wired around as I found several bypass under the dash for other operations. My main concern with bypass is the two battery setup on this 88FC. Here is that issue.
..... when the start bank is low but the house bank is full powered. the starter motor draws many amps thru the link running between the two banks. the jump wire acts like the momentary battery combine switch but full time . It is possible to turn the small jump into a mini toaster. for this concern, when I jump any bypass I try and remember to insert a blade fuse mid way in the jump.
............ one jump wire I removed was installed by someone who installed a stereo in the 88. they powered the radio to an additional source that gave the stereo power with the ignition off. I believe that jump in turn kept the ignition accessory side on all the time. I removed the key on power so the bus now has radio while docked.

On my 94PT the AT switch turns off a relay that turns off two solenoids The larger is a solenoid in the genset fan bay. That solenoid grounded out and the insulation cooked. I removed it and the large fuse that powered it was replaced with a BlueSea Breaker/Switch. the breaker is rated to be turned on and off many times. Now the AT switch continues to trip another relay up under the front hood but I have not had a chance to look and see what that powers. I will start another thread for the 94pt AT switch removal.
