I was riding the Saturday and all the sudden everything died. ZERO power. Checked the fuses and they were fine. So I changed the battery, becasue this happened to me once before. The battery had a dead cell. Put the new battery in and it started and ran fine. Looked at my tach and nothing. It wasnt working. When the battery went bad, did something fry in the tach? What wires can I look at to make sure its still hooked up? The light still works in the tach so I think its getting power. Help me trouble shoot this thing. Thanks.

 

Look at the Big Black wire (I think there is actually a small green wire inside of the black) But that wire comes out of the tach and goes down to some little box (That is where it reads the rpm's)

I have a pic that i can send to you if you want (Home drawn!!![img]i/expressions/face-icon-small-smile.gif[/img]) That's why it looks like crap

 

I will try to look at it tonight. If you dont mind, send me that drawing. Email it to mabt@hotmail.com. Thanks.

 

Sorry dude, but from some reason it says that I cant send it has permeated fatal errors?

So if you cant figure it out your self tell me and i will try to help you out.

 

Same thing. I replaced the batttery and now the tach just goes around in circles. Why is it doing that?

 

Hurycne, check the ground wire on the tach. Mine came loose and the thing went crazy.
