wire diagram

Postby kevinstro » Fri May 21, 2021 1:38 pm

Hey guys! new to the forum here. So I got a 1994 eclipse 236 sc sport with a 7.4L for free, and I'm looking for a wiring diagram for the boat. It's definitely a fixer upper, but hey it was free lol. I'm a mechanic by trade and pretty handy when it comes to fixing things so i thought a boat in need of some TLC would be fun. I'm looking for the wire diagram because none of my gauges are responding when i have my battery connected and the selector switch on. I'm confident the that the gauges are at least receiving power because my horn, bilge pump, nav lights, courtesy lights, and trim motor all work. Though the trim gauge does not work. The only gauge that does work is the depth finder. I'm assuming they all share a ground? A wire diagram would be a very useful tool for me with this project.

Power to gauges usually run through the ignition switch first, while all the other stuff come right off a fuse block.

Try for a manual for your boat at Manuallib.com . i found the manual for my '88 Gran Sport on there.
