Starting issue
Brian Miller:
Just to keep everyone in the loop. All dash lights as well as the “N” neutral transmission light works as advertised. I recently replace the GM ignition switch replace the tumbler in the old one was shot. However, the Accessory position doesn’t work? (Don’t understand)….nor did the old old one but that’s on the back burner at this point.
I need to dig into the rear start switch as well as hidden solenoid.
Frank Bergamo:
An intermittent ignition solenoid can cause the problem you are describing. Joel’s post above shows the location of the solenoid. It is a common failure point with these coaches. It is a Cole Hersee 85 amp continuous duty solenoid that can be found at Napa or any truck or auto parts store. Amazon is also another source if you can wait a few days. I used to carry a spare because of the failure rate of this solenoid, so by changing it now, you can eliminate it as a possibility of your problem. Hope this helps, good luck.
Fred Brooks:
Brian,
I agree with Frank. The 2 weakest links in the ignition circuit are the ignition solenoid and the ignition switch. Often times they get changed with off quality replacement products. The solenoid should be a Cole-Hersey continuous duty, and the ignition switch should be a Delco-Remy. The other issue to be cautious about is the "rear run switch. There was a time as I recall about 8 years when owners were using it an anti-theft device. The issue is the switch is back in a location where corrosion can develop inside of the switch. Activating the switch that was dormant for a long time can create a new situation. Now you have a compound problem. If you are comfortable using a test light, you can trace the 12volt power from the switch to the solenoid to the rear run switch to the trigger solenoid to the starter. Fred
Brian Miller:
Ok, I did some searching behind the batteries. I did not fine another solenoid back there. However, there are 2 in tandem in the battery bay. The second is “Intellitec” solenoid?
What would this activate??
Thank you in advance
Brian
Frank Bergamo:
It is probably your battery boost solenoid. Combines both sets of batteries to give you a boost when starting the motor home.
