Everything else worked fine off of the house battery except the C-80. No previous problems then the last time out it would power up & then shut off after a minute or so. At times it wouldn't even turn on. Thought it was the unit or a low battery. Before hauling the unit to a marine electronic service thought I would try connecting to one of the starter batteries but I noticed when disconnecting the house battery cables & terminals a little dirty & some small corrosion. Cleaned all, reconnected & works fine. Got lucky. Strange every thing else on that battery worked except the C-80. Read it was voltage sensitive, guess they weren't kidding. Just a note if anyone else ever has the same problem. ;)

I gave a Ray 65 with the exact same problem. I have replaced the power cord and the batteries with no luck so far. Will try cleaning the cables.

Thanks for the post.

I have a c-80 that did the same exact thing. all the folks on here told me the same thing as well. The display needs a good ground and a good clean positive connection with very low voltage drops. I checked all my connections and it has been ok. That being said, If you need to send it in to be checked out, the folks at raymarine up in NH are top shelf. you wont get better customer service.

I had same problem with my C80 DSM300, I ran a much heavier gauge wire from my battery selector to my console and it solved the problem.
