Both my trip + radio memory only work for about a minute after the key is turned off. Recently the cigar lighter power got touched to grd while the console was out. Didn't blow the fuse and not sure if it's on the same circuit. I have both batt power and ground at the proper location on both connectors. I'm wondering if the memories are kept alive by a compositor that could have been fried ? I'm too broke to replace ethier and besides that I like fixing my own sh!t.
