Does anyone know what this switch does and, more importantly, the technical side of how it works/is wired?
When I first bought my Berk, I jumped to the conclusion that the dash radio (Magnadyne MC4-LCD) would not play unless the ignition key was in the ACC position. Thinking that was a silly situation where I couldn't listen to the radio while parked at a campsite, I immediately went into "mod mode" and ran a continuous power source to the radio. I also installed the Magnadyne subwoofer, which only turns on when the radio is actually turned on (supposedly).
I have a sneaking suspicion that, had I asked the above question a year ago, I would have learned that the Radio Switch allows for the use of the radio without the ACC being on (or maybe switching to house batteries?).
The reason all this is now an issue is that I have now discovered that I have a rather substantial parasitic draw on my chassis batteries and I'm thinking it has to do with the continuous power to the radio and/or sub woofer. The parasitic draw is much more than a typical draw to maintain memory/clock/etc.
Any help on the Radio Switch and how to reconfigure my "mod" (or "configure it back to they way it was, if that accomplished what I needed it to) would be appreciated.
