Car Forum / Mercedes-Benz Cars / June 2006Alternator Light?
Hi Gang, I have an '86 190 European model. An orange light in the cluster on the far right is flashing occaisonally, and this light has no markings. Coincidentally, I have a lot of squeaking that seems to be coming from the alternator. Problem is that my shop manual doesn't show an orange light in this location, particularily one that isn't marked. Anyone know if the European models had an alternator light in conjunction with the battery warning light? If not my only assumption is that this light was put in the wrong spot and belongs in the ABS indicator position, which is right beside it. I know that the dash had been removed at some point in it's life. Thanks! It is possible it is put in wrong location. Check your alternator with a voltmeter... anything above 13.5 at idle is good. Squeaking is belt... if it is old, time to replace it. Thanks for the advice, Tiger. Belt is brand new. Don't think it could be old bearings in the alternator causing the noise? > It is possible it is put in wrong location.

But if squeaking occurs mainly with cold machine and/or at cold wheather the belt has not enough tension. It should not give in more than 1 cm or 1/2'' if you press it in the middle with a thumb with full power (equ 20 kg or 40 lb load). Rubber is shortening with raising temperature.  SignatureRoland Franzius Thanks Roland, but squeaking is consistant, hot or cold, hence my thought it was bearings. I'll be pulling it tonite to see if it is stiff, scored shaft, etc. I think tension is right, but will retry it. BTW, I should have said belt is relativly new, I changed it several months ago but haven't driven the Benz much.... > sawlled@gmail.com schrieb: > > Thanks for the advice, Tiger. Belt is brand new.

Sprayed with silicone spray, squeaking stopped, know it's a temp fix, time for a new alternator. > Thanks Roland, but squeaking is consistant, hot or cold, hence my > thought it was bearings.

I had my dads allegedly brilliant and reliable mecjhanic "repair" an alternator 4 times for $440 once on a 108. I rebuilt BOSCH was $180 I found out some time later, and they're childsplay to install.
