Choke Circuit Test
- Disconnect stator lead at choke and connect a test light in series with stator lead wire and ground. With engine running, test light should glow.
- If light does not glow, by-pass the choke lead wire and connect light in series to choke wire terminal on oil pressure switch and ground. If light glows, service or replace choke lead wire. If no light, connect light in series with ignition switch and ground. If light glows, replace oil pressure switch.
- If no light in step 2), by-pass ignition switch wire to oil pressure switch and connect test light in series with ignition switch and ground. If light glows, service or replace ignition wire to oil pressure switch as required. If no light on any preceding test, repair or replace ignition switch and repeat choke circuit tests.
