Hi Crownie,
I have the a 20MT that I just bought off craigs list. It had all new batteries. It worked when I picked it up...all functions. Then I brought it home and plugged in the charger...and BBBZZZZZT. The cord discentigrated into a smoldering mess. I think the guys that sold it knew the charger was crap. Now Im stuck with a mess. Does anyone out there have a wiring digram? The SN is 30130...it was built in 09-79. Thanks for any help. I can be reached at nvannatter @ hotmail dot com. or at 8505026660 (cell) Thank you
