High Pitch Whine From Near Starter

Recommended Posts

Hey there. So after struggling through some fuel issues, I took my car out for a ride today and all was going fine for about 20 minutes. I drove up to a friends house to say hi and stopped the car. A few minutes later, I went to start the car up and it wouldn't start. I managed to roll start it on his hill. The problem now, is there is this high pitch sound I've never heard before, sounds like it's coming from the starter. I've garaged it, and haven't tried to start it up since this happened about an hour ago.

 

Did I damage the starter doing a rolling start? I've done this before in other manuals and not had this happen. Is there a problem possibly with my starter or alternator?

It's possible that the Bendix drive is stuck in the 'engaged' position, causing the starter motor to be turned by the flywheel, which it aint gonna like! Sometimes a sharp blow to the starter motor is enough to unstick it! Happily, the starter is fairly easy to remove from under the hood.

I feel that if the starter drive was only partially engaged, ie only enough to grind off the teeth, that would be immediately evident by a lot of unpleasant GRINDING noise. Once you pull the starter out, you will easily be able to see the flywheel teeth and any damage.  You can also get underneath and pull the flywheel cover on the bottom front of the transmission.

 

If your NK is 12V and your wallet permits, I highly recommend installing a starter from an 88 M3. Straight replacement (except for wiring the solenoid which has 2 wires vs the single wire the current solenoid has). Spins faster than the old starter and draws less current. If you're 6V,  have the solenoid replaced (same as a 6V VW I think) and have the Bendix drive serviced (Lubed probably) and have unit tested.

Ok, owning one of these is turning into a fair bit of work ;) So I went to try and drive it today, and the engine wouldn't turn over. I attached a portable charger which is how I started it the other day after installing the new starter. Engine wouldn't turn over and made a weird sound a couple times, kind of a clunk. I'm hoping I didn't damage the flywheel or something now, and am going to take it apart again this weekend.

@HBChris, it didn't sound like teeth grinding, its hard to describe. I think I should pull the starter back out, and rotate the flywheel and check it. Assuming that is ok, is it possible the starter is somehow missing connection to the flywheel when trying to turn over? I think I need to start pursuing a conversion to 12v at this point rather than continue investing in the 6v stuff.

Please post a photo of your new starter motor, particularly the solenoid connections as in the 3rd picture in your Oct 5 post. If there are 2 spade connectors on the solenoid, as I have seen on new starters, you may have wired it to the wrong side (ask me how I know).

Will do this weekend, but yes there are two spades, one set has two prongs and I connected to that. There is another spade on its own, but the two spade connection is where the original starter was connected.

To that end, it turned over the first time I started the car, why would it have failed the second time?
