Thermo Time Switch: Testing and Inspection

INSPECTION OF COLD START INJECTOR TIME SWITCH





Using an ohmmeter, measure the resistance between each terminal.

Resistance:
STA - STJ 30 - 50 ohms below 10°C (50°F)
70 - 90 ohms above 25°C (77°F)
STA - Ground 30 - 90 ohms

If the resistance is not as specified, replace the switch.
