I posted a week or so ago that I broke down on the highway because of a crapped-out battery. I finally got around to testing the charging system today with a new battery (an 11AH Motobatt AGM, which, BTW, fits the battery bracket nicely), and I find that the charging system is working just fine.

I also noticed that the bottom of the battery bracket wags fore and aft violently at idle speed. I don't think anything is broken or worn; it has probably always done this. Note that my '67 has a flat frame member running across beneath the battery bracket to stabilize it, but the '70 frame does not. This has always puzzled me - how could BSA have ever decided that this extra brace was a bad idea or unnecessary? Without it, the bracket merely hangs from the top, depending on the rigidity of 1/16" flat stock for stability.

So it looks like I may have simply shaken the other battery to death, and I certainly don't want to do that to my shiny new Motobatt. For today I'll wedge a chunk of rubber between the bottom of the battery bracket and the frame tubing, and then think about removing the bracket and welding on some gussets to keep the bracket from flexing at the 90-degree bends.

My OIF batt carrier hangs from 2 rubber mounts fore and aft, i pad out the battery all round and have a strap over it, lasted 4 years so far . The solid frame beneath might date back to the early 2 x 6 volt , 12 volt system that had two 6 volters in series.

A piece of hose around the frame worked the trick. Works so well this may be the permanent fix.
