While installing my new Retrosound radio I found out, that the yellow wire for the radio does not show 12V in ACC-position, only in Run-position. I tried to adjust the position of the switch, but w/o luck. So I disassembled the switch to see whats going on inside. Here are the pics showing the position of the keys in Lock-, ACC.-, Run- and Start-Position. I do not see how the ACC. position can work at all. The other positions make sense to me. Am I confused, or are there different versions of ignition switches available? Need your help to shed some light on this. THX Lock: ACC.: RUN: Start:
The radio should work in the accessory position. If you manually put the switch in accessory, you have no power to that spade?
So the #10 brown wire off the accessory spade should power the radio. If you have a power probe, you can supply the brown wire with 12v and see if the radio turn on. That will test the curcuit
Thanks, I used a ohmmeter at the terminals of the switch to check if battery and acc terminals are connected when in ACC position. Thats why I opened the switch. What is confusing to me, is that mechanicaly there is no connection inside the switch. Either I am wrong, or the switch . Nevertheless, as the contacts inside the switch show some wear, I decided to order a new one from Rockauto. Should be arriving at my doorstep latest in one week.
First: Rockauto rocks! Ordered the switch on Monday this week and it arrived today. Second: Where can I get the application for fool of the months? I checked the new switch with my ohmmeter and oh sh... the same behaviour as the old one. Fortunately the new switch came with a manual and a illustration of the different modes of the switch. Turns out that even after almost 5 years of driving the Buick I was to stupid to know where the ACC position of the ignition lock is. I found it out tonight . Here is my excuse (believe it or not): The cars I know here in Europe have a different setup. From Lock clockwise you get to ACC and from there to On and then to Start. So I didn't think for a second that in my Buick I would have to go counterclockwise past Lock to get to ACC. Mystery solved and the Buick has a new ignition switch for reliable operation for many years to come.
