I think this thread just answered my most pressing question prior to bench testing the vintage Chevy radio I received in a box with my nicely restored 1948 one ton. There is only one wire coming from the inside of the radio,and I assumed that was power since it had half a fuse fixture attached to the end of it. Meanwhile I have been looking for and trying to understand why there was no ground wire.
So, the original intent, which I just saw in Stan's reply was; grounding via just bolting to the dash frame, am I reading that correctly? Ensuring a more reliable ground seems good advice, so anywhere on the radio frame next to the transformer should work? I have not had a lot of experience electrical bench testing something like this radio so any advice would be helpful, e.g. just hook it to the 6 volt battery in the truck (with an in-line fuse of course) or??
The exterior of the radio looks great! Inside, not so much, very dirty, appears some capacitors have been changed, lots of lumpy, cold looking soldering, and a Radio Shack speaker. Still worth a bench test first I think. I have no idea how long this radio has been setting in this box. The PO who had this truck restored and included in his collection of really nice restored vehicles passed away before having it installed, so it was just included when the family put the truck up for sale.
