93 Ls 400 Electrical Puzzle

[MISSION VEIJO LS400 OWNER]

Radio crackles and goes out when Brake pedal is depressed ONLY while idleing!

Goes back on when I step on gas! This happens only occasionally.

HELP! :(

yes, that sounds like a trunk wiring problem. I haven't experienced it myself but from what I've read, odd electrical issues can be traced back to this issue.

Do a search here and you'll find out more details.

I had the same problem. In my case I had a burned out break light. The contacts on the bulb had melted and when I stepped on the break the bulb would short and overload the system. Replaced the bulb and all was well.

possibly a bad alternator as well/.
