Cold Mixture Heater & Fuel Heater
NOTE:
Fuel heater is not equipped on all models.
- To measure resistance of CMH, unplug wiring connector. Using an ohmmeter, measure resistance between terminals. Resistance at 68°F (20°C) should be .5-2.2 ohms.
- To measure resistance of fuel heater, unplug wiring connector. Using an ohmmeter, measure resistance between terminal and float bowl. See Fig 1. Resistance at 68°F (20°C) should be 2-6 ohms.
