Volvo Owners Club Forum - View Single Post - Starter motor won’t disengage and keeps turning

I’m recommissioning a an ES that’s been in storage for 26 years. Today I fitted a new starter solenoid to the motor as the old one had seized.

I bench tested the starter with new solenoid and it functions just fine out of the car. The problem I have now is that when I turn the car over the starter motor remains engaged and keep on turning until I disconnect the battery.

I’ve tested all the wiring and can’t find any faults. The relay and ignition switch appear fine and even when I disconnect the trigger wire from the solenoid it still stays engaged and spinning.

I even tried to jump the trigger on the solenoid with a positive feed and it engages but still doesn’t disengage when I remove it.

I’m completely stuck now and can figure out what’s going on?! When I disconnect and reconnect the battery the starter disengages and it’s not until I turn the key that this happens again.

Anyone got any suggestions for what the problem might be?
