I have a 1990 Bayliner Cobra fish and ski with a 120 Force on the back. All of the accessory switches work on the dash but none of the gauges or the depth finder work, does anyone have any advice, or does anyone have any information on the boat I can?t find any.

Re: Gauges

you are mostly dealing with a blown fuse.check for power and ground at gauges and depth finder, then figure out why you have no power or ground

Re: Gauges

Check under the dash to see if the wiring for the power leads to the gauges and depth finder go to a single fuse block or if they go to a power buss. If they get their power from somewhere other than the factory fuse block, more than likely it's a bad power or ground lead going to the buss panel.

Check in line for missing/blown fuses. Use a test light. Fuses can look good and be faulty.

Re: Gauges

Your gauges are powered by the engine harness, not the same power source as your switches. Check to make sure you have voltage on the purple wire that runs to the tach, then daisy-chains to the other gauges. Also check for continuity on the ground wires on the back of your gauges with a known "good" ground. The ground circuit on your boat is the same, regardless of whether it's an engine system, or a boat system.

Re: Gauges

Check by your battery, there is probably a wire that fell and wasn't hooked to the battery. Seen this happen plenty of times.
