The 2 feeds off the ignition switch are.
1. power feed to ignition switch has a wire coming off and goes directly to the radio - I suspect this is to keep the time & station settings when car turned off. This has power on it all the time.
2. The other wire off the ignition switch is the one that powers the radio heater & acc switch when key is in the 1st position.
This is the only wire that supply these components and so should work when the ignition switch is in the 2nd position (ignition on) but doesn't.
I think this brings me back to the ignition switch being the problem.
The way I see it I have 2 solutions.
1. try and source and buy another ignition switch - does this mean I have to do something with the alarm security system/ central locking? where would I get one that is any good - car being 20 years old.
2. buy a $10 12v on /off switch & take a feed off the power wire & wire it into wire that supplies heater ,radio, acc switch, windows up/down & mount it in the dash. Then when I want to run these items when the car is running I just turn it on.
By rights it shouldn't have any adverse affect on anything else as the power is meant to be on these items anyway
