Power Circuit Checks

Connect a voltmeter between ignition ECU pin No. 5 (Red wire on 240 Series or Brown wire on 740 and 940 Series) and ground. Voltmeter should indicate 12 volts. If voltage is not present, check wire from ignition ECU connector to in-line fuse located on left shock tower (240 Series) or check circuit between ignition ECU pin No. 5 and fuse box (740 and 940 Series).
