My dash randomly stops working why?

wfletche

I have a 2003 232 Captiva with a 350 MPI Mercruiser. Randomly my gauges stop working. Some freeze where they are. Some go to full. If I keep driving they start working but can randomly fail again. All the connections look good. No loose wires. I have 12 volts at the gauges when they fail. Any ideas? Where can I get a wiring diagram?

Hey, welcome to the forum and sorry you're having that problem.  What gauges do you have?  Faria analog gauges are the most common.  In theory, you could have SmartCraft gauges, but they are rare.

Here's a set of schematics for a 280 that might help you figure it out.
