I had my dash out & now its back in & the gas guage goes down past empty & past full no matter amount of gas ???, which wire cap - green or yellow goes on which side of the guage & can the guage be ajuster ??? (getting oud is hell) :unitedstates: :icon_bigsmurf: :005:
Hi I'll take awhile guess that your gauge voltage regulator could be bad they have them at o rileys
Thats my guess too...takes about 5 or 10 minutes to change..
OK, what & where is my guage voltage regulator :icon_bigsmurf: :unitedstates: :iamwithstupid:
It is a rectangular box screwed to the back of the instrument cluster, two wires. It drops the voltage to the gauges.
If the regulator was bad, you would think that it would affect the temperature gauge.
Sorry, I have a modern underdash temp guage :icon_bigsmurf:
Testing the regulator is just like testing to determine gauge and sender performance. Unplug the sender and ground it. If the gauge is working correctly, it should go to full. If the regulator is working correctly, the gauge will go from E to F moving slow and fast. If the gauge goes quickly to full with NO surge, the regulator is not working. If the gauge stays on E, bad gauge or no power to the gauge...power comes directly from the regulator so regulator would have no power or bad.
