use the following diagram ----------------------------------------------- | + - - - | | B6 B4 | rear | - + B2 B1 | front | + - | | B5 B3 | | - + + + | ----------------------------------------------
B5+, B6- leads to zero volts when measured to frame. B6+ has 6 volts, B5- has -6 volts.
Weird, hm? I'm going to sit down this weekend and have a long look thru it. Chris
