This is a direct comparision - with a test light - clamp the wire to the neg of the battery - then tougch the probe to the + the light lights. Then touch the probe to the neg - no light.

Same thing... -Curt Date: Wed, 25 Jun 2008 12:43:34 -0400 From: "LarryT" <[EMAIL PROTECTED]> Subject: Re: [MBZ] Strange Radio Connections To: "Mercedes Discussion List" <mercedes@okiebenz.com> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original I decided to rewire the subject radio to see if I could get things working properly. There are 2 sets of wires - one set for the speakers, another set for power and accessories like cell phone mute and power antenna. The only wires I used were the battery Positive, ignition and ground. I rand a new wire from the bat + to the Yellow wire on the radio - per the picture on the radio, then found the ign on hot wire using my test light and hooked that to the red wire. Only thing left was the black wire which showed it going to battery negative in the picture. I ran it to a chassis ground - when I saw the spark I used my test light to see how 'hot' it was - lit the light completely! But the radio will not work without that black wire attached to ground! I never saw anythng like this before, hence my concern. Nothing seems to get hot and everything works - no fuses blown and the correct size fuses are in place. I'll leave it like this until some smokes gets out I guess - Thx for the help - very appreciated - Larry T (66 MGB, 74 911, 91 300D) www.youroil.net for Oil Analysis and Weber Parts Test Results http://members.rennlist.com/oil PORSCHE POSTERS! youroil.net 800-583-8601 Weber Carb Info http://members.rennlist.com/webercarbs _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
