914World.com _ 914World Garage _ Alternator Problem?

Posted by: ne14914 Jul 10 2003, 11:18 PM

The car starts great -

However, when i cut on the radio and lights the car sometimes stalls. When I turn the stereo off, the car runs fine. I dont have a multimeter so i tried the pull the battery cable off while the run is running trick. The car stayed running until I turned on the lights or stereo.

This does sound like the alternator doesnt it?

If I need to replace it, how do I get to it? I have the haynes manual, but I think I need a 914 manual for dummies, because most of the repairs I have done following the haynes manual Ive done through trial and error.

Anyone have any picks on how to get to it? or any detailed instructions?

Really appreciate any help.

haynes manuals suck!

they say it takes 4 hours to do shocks on a 914, it can be done in 15.

wish i could offer some real help, but I can't

Check out Griznant's post in http://forums.pelicanparts.com/showthread.php?s=&threadid=116430&highlight=Alternator+problem thread on the other 914 board. I'm kind of a concourse weenie but I like it.

you might have multiple problems or none. a cheap multimeter is $20 at radio shack. don't pull the battery cables while the car is running. it can do more damage.

1.)buy a meter. set it on dc voltage on the 20 scale.
2.)you should have 12.4 to 12.6 volts at the battery posts with the car off. getting down around 12.1 or .2 your battery is marginal. you might get a specific gravity battery tester if you are 'old school'.
3.) start the car. with everything off you should get 13 to 14.7 volts at idle. i like 14.1 max. myself.
4.) rev the engine up to 2k or so and the voltage should stay in the specified range.

check the simple stuff first. fuse #9 should be cleaned. all the wires at the battery should have a good connection. do a 'idle and headlight' search on the bird board.

i don't know is this applicable to this issue, but... there is a large bundle of grounds infront of the relay board. i think they are often over looked. when i did the engine bay the area hidden was kind of gross.
