The onboard computer (OBC) circuit performs the following functions:
1. Provides power to the solenoids, Forward/Reverse switch, controller capacitors and reverse buzzer.
2. Powers down the electrical system during long term storage to reduce battery discharge.
3. Activates regenerative braking when the batteries can accept a regenerative charge.
4. Turns the charger ON and OFF during the charge cycle.
5. Locks out the motor speed controller to prevent the vehicle from moving during the charge cycle.
6. Illuminates the dash warning light if there is a problem with the batteries.
7. Sends a signal from the dash light to the optional Communication Display Module.
