First, I must say thank you for everyone who took the time to help resolve a couple of boat issues I had within the last couple of weeks. It seems like things just keep coming up here recently. Oh, the joys of boat ownership! I would like to solve the issue with my trim gauge not working. I tested the voltage to the gauge and the results are: 3.27 v between G and S connections. 8.81 v between I and S. 12.06 between G and I. I tried testing the gauge by leaving just the ignition and ground wire connected and providing power. Gauge did not respond. I then shorted the sender wire to the ground on the gauge with the ignition and ground still connected and the gauge again did nothing. I then switched my tester over to Ohms, went to the outboard, traced the sending unit wires to the motor and tested the connections. The tester kept jumping all over the place and I couldn't get a conclusive ohms reading. I pushed the sending unit in manually while testing and did get a little response, but again nothing conclusive on the number of ohms. All connections were cleaned and tightened. Prior to the gauge not working entirely, it was flickering when raises and lowering the trim. Is it possible my gauge and sending unit went out at the same time or am I doing something wrong with my testing procedures? Thanks!
