do you have a good ground on your tach or on your car?
thats the prob.
Nope, i grounded mine behind one of the screws i used to mount it to the firewall with and some washers. The the actual gauge is grounded with the other ones inside the car. Are you sure you have the little pins inside set correctly?
what pins are talkin about? and as for the ground i have the m both under one of the strut bolts so i think that should be fine right?

did you clean the areas to be used as a ground? paint and rust don't usually make for very good conductors...

what he means is is the gauge set up for a 4 cyl. car? does the gauge just stop working after 2krpm or does it just not read any higher?

its like fine without bein in gear i can get it up to about 3k but when im in gear its like half of what it should be so i dont know what could be wrong. my gf's uncle is a mechanic and he said theirs a switch in the back that can change from 4 to 6 to 8 n he'd help me but i took off the back and theres no switch theres like a round thing in the corner but it doesnt say anything and it doesnt look like it should be mived at all its an autometer 2301 if someone wants to look that has one.
thanks

Sounds like it's set to 8cyl. That round button you mentioned on the back. Does it perhaps have numbers like 4,6,8 around it and a little line? If it's "lined" to 8, then set it to 4 and it will work.
