So I got in my car this morning, it was a really rainy/humid day, like 50*.

Put the key in ready position, I heard the fans turn on, the fuel pump came on, my radio came on etc. I went to start the car, and everything just cut out.

My tach went to like 5500 and sat there.

I jiggled my battery posts and when I got back in the car the interior lights worked again. So I put the key back in the ready position and everything starts working like normal, EXCEPT, my tach is now maxed out at 7000RPM.

When I shut the engine off, it drops to 6500, when I put the key into the ready position it goes to 7000.

Did my tach break? I'm really pissed....no idea what is up with that. I sorta need my tach.

 

When you turn the key on before starting, the tach is trying to go to 0 by the shortest route it can. You may need to remove the front part of the cluster and manually move the needle back around the lefthand side of the dial. The only other way would be to rev the snot out of your engine, and hope it revved high enough to 'catch' the axle shaft and pull it back around .

 

Do tach's break... hmm.. well if your dash has cracked atleast once, that should answer your question.

 

EDIT:

Pete: Thanks, I took the guage panels off and just used my finger to turn it back to 0, started the car and it worked like good again. Thanks
