my tach went out, and i tried a differant tach and it didnt work either. is there a sending unit? if so where is it? how much do they run? and how hard is it to change?


thanks,
ryan

 

are you talking about the stock tach or an aftermarket one.

i helped my friend install a aftermarket tach in his car, the connections were a +12volt, a ground, interior light, and a connection on the negative side on the coil. i guess inside the tach might have stuff in it.

you might need to do a search on here, i dont have any experience with the factory tachs sorry.

 

yeah im tlakin bout factory tach. im getting a aftermarket from a friend, them are easy to put in.

 

No the Tach has a brain and can give you the RPM by guessing. ?Yes there is a sending unit.
It pugs into the coil

 

The factory tach gets fed from the pulse side of the ignition coil. It has it's own internal circuitry so in fact the sender or processor is internal to the tach.

 

ehh new coil, i jsut got a broke *** tach. ohh well new one will be here today.
