I got in my car this morning and now all of a sudden my tach does not work. I mean it works but only after a certain time. there is no real set time. it comes on when it thinks it should come on. do you guys have any wisdom to share?

 

mazdaboy, some of the RX7's tachs seem to have a problem with solder joints breaking.

I just sent you an e-mail with a write-up I did on a DIY tach repair. Your situation sounds a little diferent, but maybe it'll help.

Good luck.

 

did not get the e-mail. bump

 

mazdaboy, e-mail bounced with a fatal non-delivery message saying it couldn't find the name. I used the address listed in your profile, so maybe there's a typo? Send me a PM or e-mail with correct and I'll try again.

 

Dave,
Can you post the fix? My tach is out and Im thinking it has to do with a bad ground somewhere, maybe the ignition.

thanks man, hope all is well!

 

My tach is also acting up, but I got used to it. I listen to the BEEEEEP
