tach doesnt work?!?!
ok, ive got the green wire going to the TACH port on the HEI, ive got the black grounded to a bolt (good ground, got another gauge grounded there and it works) white slid in above panel lights, and red hooked up to a hot spot on the fuse block (hooked a wire up to that spot and sparked it on the door to make sure it was hot), but my tach will not move for anything...what gives?
oh yeah, autometer 3 3/4 inch tach

Double check all your connections. I know I have messed up on the green one more than once. (it felt like it was in)
If all checks out good...sounds like a bum tach. |

damn Josh, get a volt meter. Sparking a wire against the door probably blew the fuse.

it's still stupid IMHO to arc a wire to see if there's juice.....

hehe, yeah, it is but i didnt know how that voltmeter worked....and i didnt think it did because it wouldnt show any volts, found out that one was a bad ground. now it reads 16 once the truck gets running, according to my book though it should only have 14-15?
