Brief Description: troubleshoot AUX battery not showing on VP
A summary as of now:
Both A & B contactors operate....A when VP gets to BEFORE START mode and B when the AUX switch on the panel is thrown.
AUX shows .3-.4 volts on VP; A shows A voltage
When AUX switch is thrown, A voltage goes up but B still shows only .3 v or so, Looks like B is tying in to the circuit but not showing up on VP. Metered all lugs...look good except no voltage sense for AUX (B) battery.
Voltage at starter contactor is OK.
E-mail pics 5126,5125,5129,5131,5132,5133 to Jeff at Aerotronics. He suggests metering out to J5- (pin 11) at VP. Passes through P1-pin 29...may check that first as it is easier to get to.
Bad pin in P1 or J5? diode direction? resistor value on sense line? continuity of aux voltage sense wire?
