Author Message   Jerry (Discovery1) Posted on Friday, February 07, 2003 - 12:24 am:    Hi: Has anyone ever had a problem with the tach needle jumping around? I have already changed the plugs and wires...any suggestions   OLIVER CLOTHSOFF (Everythingleaks) Posted on Friday, February 07, 2003 - 12:31 am:    If it is a series 1 replace the alternator. Common problem. Vehicle recieves the tach signal from the alt so it is kind of a early warning device.   Jerry (Discovery1) Posted on Friday, February 07, 2003 - 12:36 am:    Hi: Yes it is a Discovery 1. Anyone have a good used alternator for sale? Thanks   OLIVER CLOTHSOFF (Everythingleaks) Posted on Friday, February 07, 2003 - 12:41 am:    They would have had to have made a good new one first   perroneford Posted on Friday, February 07, 2003 - 07:14 am:    Alternators are typically easily rebuilt. I had mine rebuilt for under $50 over 3 years ago. Still works perfectly. -P   gp (Garrett) Posted on Friday, February 07, 2003 - 07:50 am:    as a side note. did you have the serp belt replaced? if someone else installed it check the routing. improperly routed it will show a dead tach and low #'s on your alt.   trevor griffiths (Trevorgriffiths) Posted on Friday, February 07, 2003 - 10:14 am:    I have had a few roll through the shop with a poor connection on the back of the alt for the tach signal. Even cheaper to fix than a $50 rebuild!   Leslie N. Bright (Leslie) Posted on Friday, February 07, 2003 - 10:23 am:    LISTEN TO GARRETT! The belt can be put back on wrong, which will "almost" work, but cause jumpy tach-needles and "failing alternator" or "failiing battery" symptoms.... Check your routing first! -L   Leslie N.

It turns out that the alternator was bad. Luckily I was able to get one and get back on the road...
