Power cuts out

[edsmax]

While cleaning up my 2002 240DA last night, I turned on the radio to listen to the ball game. Everytime I turned on the interior lights or even the deck lights, the radio would abruptly lose power for a few seconds and then come back on. Also noticed my dash mounted GPS would also do this. Ideas?

Sounds like a poor ground some where. Perform a voltage drop test on all of your grounds.

Thanks, I will try this. Since it seems helm related, I will start there.
