How-to disengage your starter.
A starter is an electric motor, pneumatic motor, hydraulic motor, an internal-combustion engine in case of very large engines or other device used for rotating an internal-combustion engine so as to initiate the engine’s operation under its own power. If you momentarily connect the battery negative lead to the solenoid M terminal and the positive lead to the solenoid terminal 50, with the starter motor installed on the car, the starter will engage. When you remove the power it should disengage.

I’m on my second used tested starter adn both did the same thing. I turn the car over it starts but starts screaming from around the starter, I took the first starter back because I thought it was the thought the disengage spring that was bad, but the second one did the same thing. Any ideas?

Welcome to Matthew’s Volvo Site.
I would think the ignition switch would be the most likely.

When you remove the power it should disengage. If it does not then it won’t be the ignition switch.

I don’t know if this will help diagnose the sticking issue. I tested it while it was connected to the electrical connections but unbolted from the flywheel, turned the key and it worked fine, bendix comes out spins and goes back in. bolted it back up to the fly wheel and turned it over starts the car and then starts screaming like its not disengaging. I also checked the fly wheel looks pretty clean no teeth missing or excesive wear.
thanks for the help,
matt
