SOT: 944 questions Options

[Rob-O]

Thought I’d ask here because I know that like me many of us own other P-cars besides our 914’s. I’ve posted this to Rennlist but it doesn’t seem like there are a ton of members in the 944 forum and it usually takes awhile to get replies, if you get them at all.

Bear with me as I get as much info as I can in this post.

‘86 944 Turbo, definitely a project. I’ve had it running and driving recently for quick shake downs.

Car wouldn’t turn over so replaced the starter. Got it started. Quick drive showed it wasn’t charging. Replaced the alternator. Again started and drove it but still not charging. Now starting is erratic. I can hear the starter spinning but it isn’t pushing out the pinion gear and engaging the flywheel ring gear. While installing the starter and alternator the wiring looked fine at those connections. However, much of the cabling from the battery the sheathing of the cables are cracked and flaking off. There is a ground connection on the bellhousing but I haven’t had a chance to get a good look at it (some heater hoses in the way that will need to be removed).

First question is if the starter is faulty. It’s a Bosch rebuilt but my thinking is that if it’s spinning it’s getting power. The pinion gear not engaging sounds like a problem internal to the starter.

Second question is the alternator. If I’ve had the car running with this starter and still not charging than I feel like I’m dealing with separate issues. The starter issue (since it worked when I first installed it) and the alternator, where the old one didn’t work and the new one didn’t work. Maybe wiring but I can’t really imagine much else in this relatively simple circuit.

Am I on the right path or could I be overlooking something?

hard to believe that both the new Bosch starter and alternator is bad Rob. However if the starter is engaging but the gear not jumping out to the flywheel, the starter solenoid has a problem (not grinding correct? if so the flywheel could be ragged) With the new alternator not charging as well, I would first go back to the battery and verify that all of the cables hooked to the positive battery post are good as well as clean with no corrosion, and check the ground lead from the battery to make sure it is cleanly connected to the body and that the battery is fully charged (as the alternator is not charging it) Finally, check the ground between the power plant and the body
