Instrument problems
Hello!
I'm having troubles with the instruments on my 1989 F-250 7.3 XLT Lariat Supercab. Speedo and tach works fine, but temp, oilpressure, volts and fuel level all show far less than they should. Have tried to swap the whole instrument cluster, but still the same problem.
Anyone got a wiring diagram that could be helpful, or a good idea for troubleshooting?
Thanks,
Simen
