Post by chevrolux »

went and got a tacho for the lux. made sure it was a v8 one. hooked it up like i thought it should be. took the signal wire from the tacho to the negative side of the coil. except when i rev it up its telling me im only doing 2500-3000 revs when i know its revving its ring out! anyone know what i did wrong?

check the back of the rev counter, sometimes there is a switch with a selectable 4-6-8, although if it was was on 4 it would be doing about 12k rpm,
if it is a small pod rev counther the switch is some times hidden under acover, the instruction should tell you where it is
