Dash radio died

Hopefully just a power issue?
Our in dash magnadyne is completely dead. No light! Wiring diagram shows a "constant" and a "switched" 12 volt power. I checked both fuses (one in the front run bay, second in the back closet) and they are good. There is a radio switch in the dash that kills the light in the radio when off. Assume the constant for the memory is different since the dash switch doesn't lose the memory.

Wiring diagram seems to indicate an inline fuse, can't find it.

Will pull dash panels to access the radio tomorrow, any tips welcome.
  • Thanks guys. I'll try the paper clip trick, verify the power, check the connector. Hopefully today, we pull out tomorrow for the nascar race.

    I removed the fuses and tested each is a tester, it lit up. Thought about pulling the meter out and actually verifying voltage, but thinking was it for then.

    Never had a lick of trouble with this thing, and actually kinda like it. It has MX, and the buttons and display are big enough that I can see them without my reading glasses!

    Yep, that's exactly what I was going to prescribe. A few on here and, IRV2 have described the same exact symptoms and I suggested the "reset" procedure and, it worked for many. No guaranties here but, may be worth a try. There's tiny hole in the front of the radio, I'd have to re-look at mine to tell you exactly where it's at but, you'll figure it out and, just get something like a paper clip end that will be small enough to poke into that little hole and reset the system. If that does not work, then your problem may be bigger and might have to dive into the rear plug, as has been suggested. Good luck and, please report back if you find the remedy.

  • JimM68.....I don't know if you're aware that Magnadyne went through a period where many owners wanted to throw them through the front windows of Magnadyne's offices. They would work fine and then start skipping, especially with a CD, and then work again. After about a year or so of issues, it was finally determined that the connector on the back of the radio had a bad design/connection at the hot lead. It wasn't supplying a constant/good connection.

    Make sure you have power and then check the connector. Make sure it's solidly attached to the wire and inserted correctly into the plug, There was a post a long time ago regarding this issue.
  • Is there actually 12 volt power to both fuses? Also check for an in-line fuse close to the radio, on the radio harness.
  • Our's has a fuse located right at the coach battery presumably so that when all the battery disconnect switches are off this will still provide a direct link to a 12V source and therefore maintain the memory. I know this because I removed this fuse once and the radio went dumb.
