GAUGES NOT WORKING PROPER

BTW a gauge cluster that is not grounded will cause the IVR to not function, providing full battery voltage to the gauges. This can cause the gauges to read full to over full and burn out the gauges.

A faulty IVR can fail in two ways open or closed.

If it fails open no harm but the temp, oil, and fuel gauges will not work.

If it fails closed, full battery voltage will go to the 3 gauges and can / will fry the gauges.


If your temp gauge reads correctly but your oil and fuel gauge read incorrectly, that suggests either...

1. The temp gauge is not functioning correctly
2. The fuel and oil gauges are not functioning correctly
3. There are wiring / sender issues
