Hall Board Diagnostic Procedure:
DANGER
— HIGH VOLTAGE, this testing is done with the Pinnacle power ON. Care must be
taken to avoid high voltage areas of the inverter board.
This procedure will test the Hall Board on Barrel #1.
1.
Locate Connector 'J2' on the Inverter Board
• Pin 1 - Red - +5 volts
• Pin 2 - White - Hall #1
• Pin 3 - Brown - Hall #2
• Pin 4 - Green - Hall #3
• Pin 5 - Black - Ground
Using a voltmeter in the 'DC' mode, measure 5 volts between Pin 1 and Pin 5 (Red and Black). If 5 volts is
present, continue. If not, remove the connector from “J2”, and measure the same pins on the Inverter board.
If 5 volts is present, the cabling to the Hall board, or the Hall board itself, is bad. Replace it. If the 5 volts is
not present, the Inverter board is bad. Replace it.
