When I purchased my 1985, I was unimpressed
with its starting ability. A bit weak, especially when hot. I replaced the
battery and it was better, but not great. I would often leave the
bike on a battery charger to be sure it was ready to go.
It was mentioned on a tech list there was a factory
crimp splice in the stock wiring harness. This connection
needs to be soldered making it more conductive. This connection supplies
voltage directly from the Regulator/Rectifier to charge the battery.
I soldered the connection and voltage at the battery
increased by over one full volt. This is important to allow your
charging system to keep up with the electrical demands of the Vmax.
