Magnadyne Radio

I have a Magnadyne radio cassette/disc player in a 2005 Winnebago Adventurer that is not working. I removed a panel to access the wiring and using a volt meter discovered that there was only .66 volts in the yellow power line in the harness. The manufacture believes there is an inline fuse in the wiring. However, if so, I have been unable to locate it. I checked the fuse in the main fuse box and it was ok. There is a red power wire when the select knob is placed in engine when using the radio on the road. That shows the proper voltage. Any info on the whereaabouts of an inline fuse would be appreciated. Thanks Henry D

Iwouldn't go crazy hunting it down. If necessary, just run another fused 12 volt line. I believe the Magnadyne has a fuse built into the chassis of the radio (external).

You should also know that a Magnadyne from that era had issues with the CD skipping. The problem was a bad connector at the rear of the radio. The 12 volt connector didn't make good contact and people went through dozens of these radios before Magnadyne finally figured out the problem in about 2006 or 2007.

If you do a search, you of the entire forum, you should find some info on the bad connector.

There are actually 2 +12v wires going into the connector. One is switched with the engine and the other is switched by the rado switch on the dash. Magnadye also has a fuse on the radio just under the connector.

Mine has an in-line fuse right behind the radio. Pretty easy to get to.

If yours is like mine, the red 12V line is the one that actually powers the radio. The yellow wire is the memory keep alive power which only keeps your presets alive when the radio is off.
