Thanks Randy, but no secondary solenoid, standard/typical install. It worked for countless starts before this incident. This diagram does answer a question I had, that if one used a secondary solenoid (not sure the advantage) running a wire from the "I" post on the secondary solenoid to the "S" terminal on the starter completes the circuit to close the solenoid for start. In this picture the only way for continuous engagement of the starter would be a double failure of both solenoids or a failure of the starter circuit to discontinue power via the "S" & "I" posts. I see no benefit to add one. What are your suspicions, fess up......lol
