volts at key switch closure. Adjust or replace
accelerator unit to insure that the voltage at
P3 greater than 2.5 volts before closing the
start switch.
Disconnect wire from P3. Check for short
circuit from this wire to battery negative.
Resistance should be greater than 20K ohms.
Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be 2.5 to
5.0 volts. If not, replace the control.
