Coolant Temperature THERMO Time Switch Test
NOTE:
When testing resistance or voltage values, a high impedance (digital) volt-ohm meter must be used.
- Check resistance values between listed switch terminals and from each terminal to ground. Checks should be made with coolant temperature below 85°F (30°C) and again with coolant temperature above 105°F (40°C).
- Compare results to values given in Thermo Time Switch Resistance Values table. If resistance is incorrect, replace switch.
THERMO TIME SWITCH RESISTANCE VALUES (OHMS)
| Terminals | Below 85°F (30 °C) | Above 105°F (40°C) |
|---|---|---|
| G and W | 25-40 | 50-80 |
| G and Ground | 25-40 | 50-80 |
| W and Ground | 0 | 100-160 |
