No looses wires noted and I don't see any significant corrosion. Thanks for the suggestion on the bilge ground-I checked it. They tend to corrode and low voltage stuff suffers first. 3-21 in the manual), which makes me suspect of the panel power supply but I can't sort through the rat maze of wiring bundles in the cramped spaces behind the helm panel to figure how or if the "Accessory" button gets power from a separate routing compared to the other instrument gauges and switches.īefore you start tearing into it check the main ground on the bus bar in the bilge. The Accessory button seems to share a common ground lead with the adjacent "Horn" and "Docking" light buttons (see p. The Accessory button is not connected to anything.

I've checked the ignition switch which seems to be working properly (good continuity) but I'm not getting power to the instrument panel except for 1) Bilge Pump (hot lead to battery) 2) radio and 3) the "Accessory" button on the right side.

I have that manual but as you note it's not detailed enough to help. Sounds like one of those things that might be hard to diagnose without opening up the panel behind the front seat and wiggling a few wires to see what works. I wonder if it's a faulty ignition switch or loose ground wire someplace. Not quite a detailed wiring diagram, but enough to tell you what plugs are where and what they run to.

Download the manual at, and check out the wiring harness on page 4-2, or see below.
