I key off, wait a bit, then try again and it usually works fine. I’m assuming this is the problem? My starter is only a year old and all of my wires and connections seem fine.

Thanks in advanced for any input- Andre

Are you sure that is the starter solenoid? That looks like some other power source to the starter. The starter should have a solenoid that engages bendix gear and power the the starter motor.
