stock tach wont work
 

Its a 86 GT. The damn stock tach wont work. Ive checked for loose/broken wires and havent found anything. The wiring harness on the back of the cluster is in all the way. From the shematics I see 2 wires go to the tach. Can anyone point me in the right direction as to where they go? I know one goes to the coil, but I cant see it anywhere...Thanks

Hi,
I dunno if this helps, or if my answer is stupid, but could it be the needle is broken?

Bye!

If you have the instrument panel removed trace printed circut from tach to plug, should be green wire I believe if my memory hasn't failed me. Connect a volt meter to it and ground or test light it will cause a volt meter show voltage or cause your test light to flash, if you don't have the light or volt meter,you can run your finger accross the terminal running and it will give you a slight shock if your other hand is touching metal, it bites a bit but nothing dangerous, unless maybe you got a pace maker,HAHA. If you no their is current their then replace or send your tach out for repair. If you have MSD on the car sometimes you need a adapter to make it work, I've seen cars that need it mine did't however. Good Luck.

Ive got the ACCEL 300+ actually... and it does have the green wire on it to hook up a tach, but Ill troubleshoot the cluster and get back to you.
