1998 Cobalt 220 wiring schematic

[Crbear2]

I’m looking for a wiring schematic for the 1998 cobalt 220 that I just bought. Does anyone know where I can find one?

Cobalt is usually happy to provide one if you reach out, but I don't know of any that have been posted here yet. Boats that old didn't have basic schematics in the owner's manuals either, so the manual on the Cobalt website isn't likely to help you much.

If you have a specific question, someone here might have experience with that, too. Sorry not to be of more help,

John

PS - if Cobalt does provide one, please feel free to post it to this thread!

I’m trying to troubleshoot a couple of gauges that are not reading (voltmeter and engine temp). Luckily I verified that the alternator is producing good power and the engine temp at idle sits around 140-150 degrees F. It has the VP 7.4Gi with the duo prop. I really want the temp to read before I take it out on the water for a workout. I’m wondering if there is a fuse inline with these gauges.

So glad you found us Crb2...I'm not aware of any fuses in line with these gauges. You can check the circuit breaker panel for any popped breakers. Most likely a sensor or gauge grounding issues. Be sure to check all connections on the back of the gauge.

And welcome aboard mate.

Last year I replaced all the gauges in our boat, as most of them were in various stages of failing. You can get OEM Faria Beede replacements on Amazon, they're very easy to swap out. Agree with AsLan7 that there are no CBs or fuses in line with the gauges.

You can try checking out Boatinfo or the Cobalt Owners forum; they often have wiring diagrams and manuals shared by other members. I found some great resources there when I was looking for info on my boat. Also, eBay might have some printed manuals if you’re interested in that.
