Diagnostic procedure for fuel/ temp / and alarm buzzer on Komatsu PC40-7

Green40 ยท 2012-12-05 18:27

As posted earlier I had a short in my wiring harness that required me to remove and repair the harness. All functions now work correctly with the exception of my temp , fuel gauge and warning/start up buzzer. I have verified that each item is receiving power to from the harness yet they do not function. Does anyone have the diagnostic procedure to verify if the gauges and buzzer are functional? At the time of failure the buzzer was going on and off and the gauges were flickering. I suspect they may have been damaged, but would like to verify. Any help is sincerely appreciated.
