The R8500 has two ways to feed it power. There is the 4 pin connector
and the coaxial connector. I'm assuming for bench use, you attach a
13.8V to the coaxial connector. For gel cell use, you use the 4 pin
connector. However, the OPC-023C power connector, designed for mobile
use, goes to the 4 pin connector. So is it OK to feed 13.8V to the 4
pin connector?
