Ok, in researching this issue a little further I found that a COE starter uses a dual coil solenoid. This replaces the foot lever on the starter on a conventional truck. The solenoid moves a lever on top of the starter to engage it, just like the foot lever. One coil is called the "Pull" coil, that actually pulls the lever back. (Might be "Push" I don't have the repair manual in front of me, but the concept is the same) When the starter energizes it cuts the "Pull" coil off and switches to the "Hold" coil.
I guess it is possible that there is a problem with the "Hold" coil on my starter. If that's the case I'd better take it to the auto electric shop and have the coils looked over and a new drive gear, brushes etc. put on. I need to rig up a remote start button so I can watch all this happen. If the lever moves a little or a lot when disengaging might tell me something... Thinking out loud here...
Any one got any thoughts about this? Thanks,
Scott
