Ammeter zero level

I have approximately adjusted the ammeter zero level on your card on my car, but each car is slightly different, so we will now zero the ammeter. First make sure that no fans or A/C, lights, radio, or other loads are operating. Quickly tap the mode 1 button on the joystick. The mode 1 active led should light. This mode disables background charging. All other leds should be out, but one assist or one charge led may be on.

Adjust the Ammeter zero adjustment potentiometer until all of the amp leds go out. This is a sensitive adjustment, so turn slowly. If more red/amber leds come on while you adjust, you are going the wrong way.
