Theory of Operation

Test 4: confirm battery amp monitor connections

Leave the negative lead of the DVM connected to pin 3 Logic ground. Connect the positive lead of the DVM to confirm that pin 11 measures the -12V.

Next measure pin 10, to confirm that the +12V is ok.

Finally measure pin 9 to confirm that the amp signal is working. The voltage of this pin will be 0 if no amps are being put into or removed from the battery, so you may need to take a short ride to confirm that this voltage changes with the assist and charge bar graphs. 0.02Volts per amp, + for assist, - for charge. That would be 2V for full assist, and 1V for full charge. All we need to do here is confirm that this voltage changes when the bar graphs change.

Drive to charge the battery to at least 3-5 bars, as we will need to try the assist during the operational test.
