Alternator-Powered Choke
- Disconnect electrical lead from choke cap. Turn ignition switch "OFF". Connect one test lamp lead to positive battery terminal. Attach other lead to choke cap terminal. Test lamp should light. If test lamp lights, proceed to step 3). If test lamp does not light, use a jumper wire to connect one end to choke clamp shroud and other end to battery negative terminal.
- Test lamp should glow. If not, connect jumper wire directly to choke cap ground pin; if lamp glows, correct poor connections between choke clamp shroud and choke cap ground pin. If lamp does not glow, replace choke cap.
- Leave test lamp connected and remove jumper wire. Test lamp should glow. If not, locate and repair open in ground circuit. Reconnect electrical lead to choke cap.
- Connect test lamp between choke cap shroud and battery negative terminal. Start engine. Test lamp should glow. If not, locate and repair open circuit between choke cap and alternator stator terminal. If no open circuit is found, check alternator output and service as required. Stop engine and remove test equipment.
