Pretty sure it's an earth problem.....
.....but I'm not sure where to start.
Yesterday in boisterous conditions the dials on the boat stopped working. The engine is a Yamaha F100 and if I describe what happened maybe someone will help me with where to start my search.
The tacho stopped reading and maxed out at 7000rpm, jammed against the stopper. the multi guage (fuel, trip, battery, speed) stopped working at all and blanked out. The tilt and trim stopped working but the VHF and two GPS units were fine (thank goodness).
When we got back to the ramp i cut the engine at the ignition key, turned it back on and everything worked fine!
I'm thinking this might be either a simple earth (if so where) or could it be an iginiton key barrel issue????
Hope someone can help.
