Hi my name is***** will be glad to help. Check for power to the S terminal on the solenoid when this happens. If there is power there when this happens it is a signal problem causing this. Check the relay/solenoid on the firewall/fenderwell for sticking engaged or for a shorted ignition switch. Check for power in and out to verify. Let me know
Pleasure to help Tom. If there is no power there to signal the starter to engage but it is sticking, check to see if the drive is getting jammed into the flywheel and not releasing meaning the starter will need to be shimmed. Let me know but if the signal wire is still powered for some reason the problem will be on the ignition circuit side.
