stock tach wont work

[Darkside]

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.
