When I disassembled my '55 Speedster, I found a short piece of flat braided wire (like the braided cable that is used as ground between engine and frame) attached to the lower mounting screw on the Windshield wiper motor. The wiper motor mounts in the upper center part of the firewall just above the metal lip. This screw is the one that attaches through this lip near the top of the firewall. This flat cable was about 4" long and 1/4" wide flat braided wire. Does anyone know what that 'ground' cable may have been attached to? When I found it, it was attached to the wiper motor screw, but the other end was just loose.

Thanks,

Sounds like the sort of grounding strap that was affixed from the body to the hood on some cars. May have been an aftermarket addition. This was to help suppress radio noise.
In your case, it's certainly not a "factory" part.;)

Some of the radio installation instructions show a small copper braided strap attached to (wrapped around) the oil pressure guage tube. Does it look like it would reach there?

The wiper assy is on rubber grommets for noise/vib and I bet that ground cable is to ground the motor? My '53 had a copper strap on the lower center screw for what I surmised was that reason. I was formed special and not a loose cable tho. Also had a star washer under that screw but not the others to dig into the metal. I wonder if its not hooked up where the motor is getting a ground? Maybe through the linkage pivots (and probably not a good thing if it is!).

All that style wiper motor have a ground tab on one screw, like you talk of. Of course, the strap COULD be there to replace a broken tab.:D
