There will always be differing circumstances, but the constant should be your operating voltage. Just like on a Amp, the switch on is just for that, it's a relay. I'd bet your problem may be solved if you ran a dedicated feed to the battery instead of through the fuse box. Just leave the key on where it is now Travis '66 Fastback -----Original Message----- From: type3@vwtype3.org [mailto:type3@vwtype3.org]On Behalf Of Mark Healey Sent: Wednesday, August 07, 2002 1:06 PM To: type3@vwtype3.org Subject: Re: [T3] Not enough power for radio On Wed, 07 Aug 2002 10:10:46 -0700, Brian Schlepp wrote: >I have had similar problems with other accessories, but never the >radio. >Have you checked all the grounds?

I just found a constant and a switched 12V on the fuse box and connected. One thing I've never been able to find out about car radios is whether the swithced 12V is the main operating voltage and the constant 12V is just a trickle to hold the presets or if the constant 12V is the operating voltage and the switched 12V is just a control signal.
