volts. Adjust or replace accelerator unit to
insure that the voltage at P7 is more than 3.0
volts before depressing pedal.
Short circuit between battery negative and P7 in
accelerator input circuit.
· Disconnect wire from P7. Check for short
circuit from wire to battery negative.
Resistance should be greater than 4.7K ohms.
Defective control.
· Disconnect wire from P7. Measure voltage
from P7 to negative. Voltage should be greater
than 4.5 volts, if not, replace control.
