Re: a couple boat rewiring ? tack/fuel gage

Most tachs have a separate feed for the light. Have you determined that there is actually a light in yours? If you post a picture of the back, we may be able to suggest how to separate the light from the main power.

On some tachs the internal light is on any time the key is on. No big deal. The instrument lights are normally wired to ths NAV side of the NAV/ANC switch.

You are going to be very limited as far as finding another tach is concerned. Your motor has a 20-pole stator, and not many tachs are compatible. When I was looking for one, I had to get a used one from eBay; I couldn't find a new one that would work.

Sorry you didn't find the troubleshooting thread helpful for your fuel gauge problem. Most people don't have an extra gauge handy to swap in, so you had one up on them.
