Geoff, The brads that hold the contacts to the board are 2 different kinds of metal as well as the brad it self. It takes a special way to solder the 3 dis-similar metals, so if you try it don't hold the heat to long on the brad or the trace on the board will turn loose. I practiced on several boards till I got it right and it is worked out good so be careful. On the contacts, don't sand except with something like a 400 grit emery strip. Contacts have a small amount of silver on them to help prevent rust and to enhance the contact connection. If you sand them you will take off all the silver.

My tail light boards seem to be in good condition, it's just the connectors that seem a bit dirty/oxidized and perhaps a bit loose. I was hoping a good cleaning would improve things a bit. A friend suggested trying to sand the metal contacts a bit to remove what's ever on the surface. Might give this a try if cleaning alone doesn't work. - Geoff To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
