Starter solenoid problem

I have a Perkins Prima 27 hp. engine on my Rawson. It had not been started for about a year. I turned the key, solenoid engaged the starter, starter turned, engine tried to start so I know it will eventually. But...when I release the key, the engine stops cranking, but the electric start motor continues to whine.
So to my knowledge...the Bendix throw-out mechanism is disengaging like it should but the copper contact washer is staying engaged across the contacts for some reason.
Do you think this is right? Has anyone experienced this before?

Hi Celestialsailor
Same thing happened to my starter on a Lehman turned out to be the bendex spring was shot, I just replaced the starter as it was giving signs of further problems, but it could have been rebuilt.

Your Magnetic Switch Relay (either integral, or remote from starter solenoid) is probably sticking (closed).

Tap it lightly, and if it releases (opens) - replace relay.

If you have the Delco-Remy Starter (typical on Perkins engines) then the Field Service Bulletin may help:

Thanks Gord. By Magnetic Switch Relay do you mean the unit that piggy-backs the starter which I call the starter solenoid or the separate starter relay? If it's the relay sticking in the closed position...wouldn't the starter crank? In my situation the bendix gear releases but the motor continues to turn.

That occurred to me after I posted.

Another possibility is that the Bendix is actually not releasing, and the flywheel is driving the starter, in which case the relay won’t be energised (after start switched off) .

When I release the key, the engine stops cranking but thew starter continues to whirrrr. I'm thinking the copper washer which engages across the power studs is some how allowed to stay while the bendix plunger is released. Maybe the washer has come loose. I will know in June when I go back to the boat. I didn't want to work on it this time around until I totally cleaned the bilge and engine. I hate working in a grease ladened area. You can tell the area has had little maintenance.

Sure sounds like a stuck contact to me.
Does the keyswitch stick? How about another relay between the key and the starter solenoid? I've seen that lashup before....

Hi Steve...If the key switch stuck the bendix would be engaged and the engine cranking non-stop. The same with the starter relay between the key and starter. I'll let you know when I crack the thing open.
