L-JETRONIC: TEST CHART

THERMO-TIME SWITCH

---

Measure:

Resistance between terminal "W" on thermo-time switch and ground.

Value:

0 Ohms with engine temperature below:

• 50 F (thermo-time switch 0 280 130 219)
• 56 F (thermo-time switch 0 280 130 221)
• 86 F (thermo-time switch 0 280 130 214)

Infinite resistance with engine temperature above:

• 68 F (thermo-time switch 0 280 130 219)
• 74 F (thermo-time switch 0 280 130 221)
• 104 F (thermo-time switch 0 280 130 214)

Deviation:

If resistance value lies outside of specification, thermo-time switch is defective.
