You need a wiring diagram for that answer. each vehicle is different.
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 could possibly have some common wiring or computer problems that affect the tach and transmission. Run a code check on the computer to see if any problems. show up.
I need the pinout for a 1968 Pontiac Firebird hood tachometer. Specifically, the tach side connector. I have three wires coming from the engine side and seven off the tach. One broke off and can't immediately see where it was. Help?
how do you hook up a alternator on a 175 Massey Ferguson tractor with tach drive on it the plug has been cut off..
Tach is driven by a motor signal, speedo is from the trans the sensor is bad on the transmission
Yes, a disconnected or broken TACH wire from the HEI distributor cap can cause a '79 trans to fail to start.
negative side of the coil
At the dist there should be one to power the dist. & one for tach signal. Unplug one & see if car starts or if tach still works. Can't really remember for sure as its been a while lol. My 1972 tach wire is brown and it has a inline fuse from the factory. Your tach wire will be connected to the negative side of your terminal witch is labeled "tach".
You do need a switched live to the bat terminal, but not to the tach terminal. The tach terminal is the negative side of the coil, the bat terminal is the positive side of the coil. Normally the tach terminal is for the green wire from the tach.
possibly a bad ground check your wiring
Buy an instrument panel with a tach from a junkyard. The wiring is in place and is plug and play.
