Thanks for all the input on this minor, but interesting subject. After reading all the posts with interest, I removed the ugly little brass and green knob, replaced the nut on the positive ground post cable end bolt with a wing nut, installed those little red and green felt anti-corrosion washers, rigorously cleaned the posts and cable end clamp internals, slipped grandpa?s old ½? open-end wrench in the battery tray next to the battery and snugged everything up. The felt washer elevated the cable-end clamp just enough to spin the wing nut after I had relieved part of the lead cable clamp with a wood rasp. Tomorrow, I?ll try and find some of that Kopr-Shield stuff. If I remember, I?ll change out the wing nut for a hex nut at the next concours judging. In the mean time, I feel I have a safe, reliable, cheap, easy to operate and effective solution, although it has no anti-theft protection. I?m also reporting/repeating an excellent 6-Volt battery for the ?55 C300. It is the Workaholic by Interstate Battery, a Group 2 with the proper dimensions and top post locations. Model 2XHD. 600 CCA, 750 CA. A black battery with three black plastic stoppers-friction fit. Any suggestions for proper color of the stoppers? Red, green or ??? By removing the vinyl warning tags, it looks fairly authentic and innocuous. I think I heard there is no judging penalty for a black battery and I?ve not heard any good reports about the longevity of the reproduction batteries. Onward to bigger and better things. Thanks for the input.

How about that for Keeping it Simple? Was wondering about that while reading all the complex suggestions for simply removing the cable. I have done so for at least 30 years. I make use of Kopr-Shield conductive and anti-corrosive surface compound wiped on both the battery posts and terminal clamps. That way a mere twist of the battery cable end either disconnects or connects and you are good to park or go. The material is, if I remember, available from Eastwood. I use it on all electrical connections as well. 300ly, Gil C. In a message dated 6/13/2010 10:30:26 A.M.

What I've been doing for years is to never quite tighten up the negative clamp and then I can easily twist it ON or OFF without use of tools. I always disconnect the negative cable whenever I park the car at either a car show or it's storage area. My theory is that it's hard to have an electrical fire if you don't have a dc loop in the vehicle. Just my 2 cents worth.
