Title: Switched vs. Unswitched Radio Power
Post by: tdun824259 on January 29, 2005, 15:30:52

I'm replacing (but keeping) my becker radio.  For those of you who have done this what is the best and most conveinent sources for switched and unswitched power.  I've also added a new power Hirschmann antenna that I've connected to the glove box compartment. That seems to work fine.  I can't find an unswitched power source for the new receiver to retain it's memory.  I've tried the clock (should have constant power) but no luck.  Any ideas from the group would be appreciated.

Fuse #1 is always powered.

Hi Tim,  Your car should have a small fuse box located in the engine compartment along the passenger side fender near the radiator over flow tank.  I think the box has two fuses at least one of which is specifically for the radio.  Most power antenna that I have seen have a ground and two power inputs.  One input is always +12V and the other is switched power from the radio.  I think the second fuse in this box could be used for the antenna.
