38 tiara open electronics issue
Can someone please assistant me with voltage gauges they don’t read anything, but boat is running fine. I have had problems in the past month with the oil gauges. We did do the manual gauges and now the oil pressure is fine according to the manual gauges.  Why don’t I have a reading on my voltage gauges? Any help would be great.

First step is the check the pins on the back of the gauge with a voltmeter. Just pull the dash back to access. the volt gauges are easy. The wires at the top are for the backlighting, the two on the bottom are positive and negative. If you have voltage on the back then the gauges are bust, otherwise you need to keep tracing the wires back to find the problem. Many times its a grounding problem.
