Cap Continuity Test (All-Electric Choke)
- With air cleaner removed and engine off, connect an ammeter in series between choke cap terminal and its lead wire. Start engine and note ammeter reading. Peak indication of approximately 15 amps, should be observed, followed by a drop to less than 1 amp. in less than 3 minutes.
- If no 15 amp. peak reading is observed, place an external heat source (100 watt light) against center of choke cap for several minutes. If current fails to peak at approximately 5 amps, and shows a steady current of approximately 0.8 amps., replace choke cap. If no current is shown, check choke circuit, fuses, relay and oil pressure sending unit.
