AGRON80, the relay is behind the battery, yes? When you remove the battery all devices that have memory will be lost. Have no fear, EL CHEAPO is here. Do as I and a great number on the MBCA forum. From Radio Shack or where ever, get a cigarette lighter plug and a 9 volt battery snap connecter. Solder the 2 leads from each together keeping the polarity correct. The center nose of the plug is positive. After you've finished this advanced electronics device and have a battery plugged on, plug it into your lighter recepticle. Remove the battery. Turn the ignition switch to the acc. postion. This little Jim-Dangy Gadget will be to your rescue. Happy Trails Beep Beep from Houston, home of a few "EL CHEAPOS"

try me for a pressure brake Bleeder that is the spitting image of the $45.00+ advertised in the STAR. How about less than 15 bucks.
