I am about beside myself. Yesterday, I was trouble shooting a vans oil temp gauge in my RV-9 that had been giving me readings I did not believe. After checking the connections, removing the sender unit and inspecting , cleaning and reinstalling the wire, and checking the ground connections. I attempted to start..being cold, and the battery a bit low, it would not start..I hooked a small portable battery booster to the battery, and started the engine. While waiting for the engine to warm up, and see if it was going to register temps, with the engine at idle of about 1000 rpms, I switched the alt field off, and then back on, at which time all the vans stock steam gauges promptly fell to zero. This includes the oil pressure, tach, volt meter, amp meter, both fuel gauges and even cht ..which were just begining to register. and fuel pressure. ARGHHH.. IN other words..ALL the gauges, with the exception of my Garmin G-5, and the gps (which is powered by cigar plug)..These two soldiered on uneffected.
NO Circuit breakers were popped. After cussing myself for this obviously dumb move, I shut the engine off and began to examine behind the panel.
This panel is fairly standard in the old school way, and wired according to the manual I received when I bought the machine.(I didnt build it).
To my consternation, I can find nothing wrong behind the panel..12 vlts on all the gauges with the master on..grounds all good..I have even made jumpers and grounded to alternate spots, think with 12 volts on the gauge..I must have lost a ground..nothing helped.
Did I fry all those vans gauges? ALL at the exact same time..with nothing else affected? Seems a far reach to me..but what do I know?..Less every day it feels like! Any suggestions welcome, including chastising!
Help!
