Could be the tach is set for 6 cylinders?
You should hook up the wires for a tach on a 1985 Chevrolet s10 blazer to the negative side of the coil. You should be sure to identify the positive and negative sides of the coil.Ê
Chevrolet Firing Order 18436572
at the tach it is white-pink green at coil
green
negative side of the coil
hook your green wire from the tach to the white wire from the coil PAC it should be a white and a yellow wire coming from the coil. the tach should have a white wire that will be your light inside the tach a red wire for power and a black for ground.. good luck
white if its tbi
check the fuse panel
tachometer quit working - all else on the fuse works. where is the tach sender? Is it possible to check the tach and sender without removing the instrument cluster? where do I find the wiring diagram for the tach and sender? auto: MB300TE, 1991 GASOLINE
You need a wiring diagram for that answer. each vehicle is different.
