So my 02's tach quit working, don't know why, when you turn it on it sets at 0 but when you start it it doesn't move. when you rev it it kind of jiggles a lil bit (could just be from vibration) but that's all. Any idea on where to start? Thanks.

 

Do you own a service manual for the quad? If not....get one. Thats always the best first step .

 

Yeah I need to break down and just buy one, haven't needed one for going on 8yrs but at the moment I don't have one so im hoping someone will chime in on a hopefully simple fix.

 

i think you have 3 or 4 wires coming from the tach one is positive ,one ground,. one tach signal wire goes to the coil on the left side as your sitting down, you might have a fourt wire that is the light
make sure your gound is clean and secure then check the wire from the coil is not broken the positive is fine cause the tach moves the bad news is the tach probly faulty you could send the tach to autometer and they could check it for you

 

Alright thanks ill check the wires if not ill call auto meter about maybe fixing the one ive got. Any ideas on where to buy a new one? Thanks again.
