J1 controls polarity of the Master Switch input.
J2-J8 control the polarity of output T1 through T7
J9 controls whether T12 is tied to the Master Switch input T10 or independent for an
Isolated Battery Input.
<=-CAUTION-=>
When J9 is in the MASTER SWITCH position T12 is tied directly to T10. A direct short
circuit will occur if an Isolated Battery Input is at T12 and a ground Master Switch input
is at T10.
