ELECTRICAL SYSTEM AND TESTING

ELECTRICAL CIRCUITS

See General Warnings, Section 1, Page 1-1.
The IQ System vehicle has three distinct circuits:
• Control circuit (Figure 11-2, Page 11-6)
• Power circuit (Figure 11-4, Page 11-9)
• Charge circuit (Figure 11-5, Page 11-10).

CONTROL CIRCUIT

The control circuit consists of three individual circuits:
• Onboard computer circuit (Figure 11-1, Page 11-4)
• Solid state speed control circuit (Figure 11-2, Page 11-6)
• Tow/Run switch circuit (Figure 11-3, Page 11-8).

ONBOARD COMPUTER CIRCUIT

The onboard computer (OBC) circuit performs the following functions:
1. Powers down the electrical system during long term storage to reduce battery discharge.
2. Turns the charger on and off during the charge cycle.
3. Locks out the motor speed controller to prevent the vehicle from moving during the charge cycle.
4. Illuminates dash-mounted battery warning light if there is a problem with the batteries or battery charger.
5. Sends a signal from the dash light to the optional Communication Display Module.
