Car Forum / Honda Cars / November 2005Alternator job, PART 2
I just noticed 2 problems tonight for the first time and I wonder if it might be related to having the alternator changed Saturday: - The cigarette lighter dont work anymore (but it worked until this morning, which is 36h after the change). The blue light around it is still on but much weaker - I heard a high pitched squeaking sound a few seconds after I started tonight, that sound disappeared after that (loose belt?) Once again, first time I hear that. Other things to know: Today is kinda cool (for Texas) (50F), lights, radio, A/C all that works just fine. anyone has ideas? > I just noticed 2 problems tonight for the first time and I wonder if it > might be related to having the alternator changed Saturday: > > - The cigarette lighter dont work anymore (but it worked until this morning, > which is 36h after the change).

Yes, this is exactly the description of a loose alternator belt: Squeals on first startup, then quiets down. If you're handy and have a set of metric wrenches and sockets, it shouldn't be hard to tighten it up yourself. There's a free online manual at www.autozone.com , On the left, click on "Repair Info," then "Vehicle Repair Guides." Click on car year, make, and model, etc. > Yes, this is exactly the description of a loose alternator > belt: Squeals on first startup, then quiets down. > > If you're handy and have a set of metric wrenches and > sockets, it shouldn't be hard to tighten it up yourself. The radial load from pulling the side of the output shaft that exceeds the factory spec by a tight belt will cause premature wear of output shaft bearings. Instead use a grip compound or replace the worn belt. Here's a rule of thumb: Push down on the belt halfway between pulleys with a force of about 24 lbs. The belt should deflect 12-17mm. >> Yes, this is exactly the description of a loose alternator >> belt: Squeals on first startup, then quiets down.

If you have AC and your alternator belt is common to the AC compressor and it was reinstalled tighter than when you brought it in, it could be the compressor clutch that is making the high pitched squeal from the excessive side load. This happened on my '90. belt never was slipping. Frank |
