Tach Acting Up
Hey guys, was towing home wood last night when i noticed the tach was messed up, i was doing 120km/h and it said i was sitting at 1000RPM. I knew this was not right. thought maby a computer glitch, when i got home turned the truck off, then restarted it, the tach worked properly.
So today when i was driving it was working like it should, i went to pass a car, when i looked down the tach didn't move, got like stuck, i took my foot off the accelerator pedal, it dropped like it should, when i stepped on it again it shot up like it should, works for a bit then starts acting up again.
I replaced my alternator a month or two ago as it was shot, donno if they still run the tach off the alternator anymore?
Any Help Appreciated!!! Thanks in advance!!!!
