Troops.......As some of you suggested, the electricity "leak" that has been
driving me nuts is in the new Kenwood KRC-2007 radio. Even though it is
installed correctly, the memory side of the radio will pull down the
battery in about three to four days. Now I see the Fantastic fan will do
the same thing. I have the stock fan, but I'd sure appreciate some
suggestions on curing the radio problem before I have to go though the
agony of changing it again......Jim Davis on the Oregon Coast
 
Ouch! That's gotta' be either a bad radio or a bad battery. There's no way
that a properly installed radio should draw down a good battery in 96 hours
or less. Check out the battery condition testing information at:

I had a similar situation last winter with my Jeep Cherokee. If it sat more
than a few days, the battery would discharge enough that it wouldn't start.
Worse still, if the security system was armed, on a cold night the voltage
would drop low enough to set the alarm off. The flashing lights and blowing
horn would quickly kill the remaining charge. A new battery from WalMart
fixed it.

Good luck!

Jim--
Why not put in a genuine separate "off" switch in the line to the radio?. You
would loose the memory but when traveling the memory is not much good anyway.

I installed the radio connected to the coach battery and not engine
battery. Then I also put a switch inline to turn off the radio completely.
You lose the time but not channel presets on most modern radios.

station presets or clock. On the positive side, this allows us to play
the radio / CD player without having the key turned to "accessory". When
I turn off the engine, I next turn off the radio toggle switch.

When we put our new radio in, there were two power hookups for it. One
power hookup allowed it to keep the memory but draw very little
power. This power hookup is meant to always be "hot" which is what we
did. The second hookup was supposed to be switched so that it was only
"hot" when the ignition switch was on. We installed a separate switch so
that we could manually switch this one on and off and used diodes so that
we could also have the ignition switch turn it on and off. When this
switched hookup is "hot", the radio seems to draw a decent amount of
current as it gets warm to the touch. If this second one was switched on
all the time, I could see it drawing down the batteries. If I recall
correctly, all the major current ends up being drawn from the first, always
hot, hookup. The switched hookup just acts as a signal to tell the radio
to turn on and start drawing more current.
