Q: I am currently restoring a 1966 Suzuki T20. However, some of the parts were disassembled when I picked it up. One area in particular is battery/rectifier mounting. Where is the rectifier mounted? Also, there is a clip attached to the battery box that is made of copper or brass. What is that? Any help would be great. Thank you.

A: I had no idea where that rectifier was located, so I had a look at the schematic on cmsnl.com to see if they could help. It’s not the clearest scan, but it looks like it bolts to a lug on the left side of the top left frame tube right in front of the cross bar toward the rear. As for that clip, a couple of things on that same schematic are possible answers, either the battery holder plate, or more likely, the brake switch holder bracket.
