non working tach

Post by 92tank »

so i got another one of my projects running, but the tach only reads 1100 rpm all the time. when you turn the key on it jumps up to the 1100 mark and stays there. also the oil pressure gauge pegs the high side (new sensor allready put in) did i get the wrong one?

Don't know about the tach, but IIRC the oil psi pegged means its grounded/shorted. Pull the wire from the sensor n see if it changes, you may have just gotten a bad sensor.

i think its was the wrong sensor, it was for the light not the gauge, but the one for the gauge was not right either. it had the wrong style plug.
