QuestionMy ranger started smelling burned and stopped smelling found all gauges on cluster not working. replaced burned fuse after that fuel and temp gauges were not working. Remouved cluster and found small PC board smelled like burned. What may have cause such thing to have happened? Are the gauges no good or the Little PC board (ampliphier) no good?
AnswerHi Wesley,
Ford uses a tiny module called a CVVR (Constant Variable Voltage Regulator) to interpret the data received from the various sensors that show usable data that you can understand in the form of a gauge. When this module goes belly-up, it sometimes cooks the whole cluster.
Replacement of the cluster will probably be the only thing that will get you working instrumentation again.
Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).
Thanks for the question, I hope this information was helpful to you.
