Test 4: confirm battery amp monitor connections
|Move the negative lead of the DVM to pin 11 batter sensor negative. Connect the positive lead of the DVM to confirm that pin 10 measures the +24V.
positive lead to pin 9 to confirm that the amp signal is ~12V. The voltage of this pin will be 12V 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.
0.02 Volts per amp, + for assist, - for charge. That would be 14V for full assist, and 11V 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.
