Subject: Re: <E30> Blowing Fuse #23 After DIY Stereo Installation

Did you figure this one out? I did the same thing on my '84 318i.
You've grounded your wire from the dash lights going to the stereo.
To figure out which wire it is, get a multimeter, and disconnect the
radio, check all wires for voltage that varies with the brightness
of the dash lights.
Be sure to check your headlight switch, I fried mine doing this.
Get an '86 or newer switch as a replacement, it's an improved design.
The circuit board has traces on both sides instead of just one.

[...] I did
get it fixed. A couple of responses properly identified the problem; one
even said which wire to disconnect and cap (gray w/red). Thanks for the
note, and thanks for setting up the homepage--I have had it bookmarked for
about a year!
