Just got my car back from a major tuneup last weekend. It was running perfectly. Went out for a drive today and wasn't even around the block before 1) the alternator light went on, 2) the voltmeter stopped working, and 3) the tachometer started bouncing between 0 and the correct value. With the brake pedal down, the tach always goes to 0. Right when this started, I heard a mysterious clicking under the passenger seat. The car still starts and runs perfectly, but I'm afraid to go anywhere now.
I looked under the passenger seat and everything appears fine. I pulled the voltmeter and found that the light bulb has fallen into the gauge (I'm working on getting it out). Any ideas on where to start troubleshooting? |

I found a post by Dave Darling who said:
QUOTE The no tach/Alt light on/etc. is a blown fuse. I think #9, but could be #8. I'm heading outside to have a look! UPDATE: Both #8 and #9 were blown. Now I remember my mechanic (Brad Mayeur) telling me that the fuse for my wipers has a short and kept blowing the fuse, so I assume that accounts for one of the blown fuses. For whatever reason the other decided to blow today too. |

Glad you found it, at times corrosion can build up on the end of the # 9 fuse and its connections in the fuse box, it causes the same problem, a little sand paper takes care of it, but in an emergency rotate the fuse to make a better connection, be careful it gets hot! Good luck, Mike |
