Mode Control Motor Test

Mode Control Motor Test




1. Connect battery power to the (1) terminal of the mode control motor and ground to the (2) terminal.
2. Using a jumper wire, short the (2) terminal individually to the (3), (4), (5), (6), and (7) terminals, in that order.
The motor should run each time the short circuit is made.

NOTE: If the mode control motor does not run when shorting the first terminal, short that terminal again after shorting the other terminals.

The mode control motor is normal if it runs when shorting the first terminal again.
