We seem to be experiencing some kind of electrical problem when connected to shore power only ( with the red wire (+) to the battery disconnected) when we turn on any 12 volt power source (15amp) the radio (Kenwood) will turn off and then a second or two later it will turn back on this happens with any 12volt circuit you choose the best I can tell is that the original radio harness which is located under the TV cabinet behind the pull out drawer is connect to the two 30amp “Polarity” fuses along with the propone and carbon monoxide sensors but if I reconnect the battery wire and turn on the battery disconnect switch while still being connected to the shore power the problem does not exist or just being on battery power alone the problem does not exist. I think my problem may be with the PARALLAX 7300 series model 7345 converter. Any help you can give would be greatly appreciated.

I guess I'm not understanding the problem, as it does not seem like a problem.Connect your battery and turn on the battery switch and it works fine as it should?Why would you be disconnecting your battery wire?

Sounds like you have an slow auto transfer switchtransfer switch link

Yes i can use the battery disconnect switch each time but never did before.

Not sure I follow what you are doing. What exactly do you do when you turn on a 15 A 12 volt source? My unit has circuit breakers on the 115 VAC and fuses on the 12 vdc. If you are switching 115 VAC circuit breakers, it is possible that you have a source voltage dip. If you are plugging and unplugging fuses, it could be a loose connection. If this occurs when you turn on any 12 vdc lamp or whatever, it could be a loose wire or a failing converter. My first step would be to disconnect all power sources, and tighten connections. If you meant it happens when you switch any 15 a 115 VAC circuit breaker, also check your source. The problem sounds like a momentary dip or loss of voltage to the radio.
