I have a 70 RR with Rallye dash and the Tach stays pined all the time Is it a bad Tach?
It's redlined to 8 grandDefine pined? A picture?
Does it do it when the switch is turned on or after the car is started? I would start by removing the tach wire from the negative side of the coil and see if it goes back to 0.It's redlined to 8 grand
NoDo you have a "modern" speaker mounted in the dash? Magnet will do funky things with gauges.
If it goes back to 0 what next?Does it do it when the switch is turned on or after the car is started? I would start by removing the tach wire from the negative side of the coil and see if it goes back to 0.
Wiring error or defective tachometer. Check your battery and ground on the back of the tachometer. Also check that the tachometer wire to the coil is not grounded somewhere.If it goes back to 0 what next?
