when I bought the car it had a painless wireing kit installed except the guy who wired it obivously did not have a clue so I went thru and basicly rewired everything to where it suppost to be, everything works now... except one problem on the instrument cluster all gauges work untill I turn the park or headlights on then the tach, volts, and oil press drop to zero???

I've been at this for 2weeks and still can see the problem as the old saying goes... once you been trying to fix a problem for awhile you could stare at it for ever and not see the problem.. So Just looking for some ideas

Thanks, Tim

 

Check all the Ground wires from the lights and dash. Make sure they are separated. Could be "back feeding" though one.
