L-JETRONIC: TEST CHART

INJECTORS

---

Measure:

Resistance of coil winding in injector.

Value:

2-3 Ohms between terminals on each injector.

Deviation:

If winding is open (infinite resistance) or shorted (no resistance), replace injector.

Check resistance of series resistors for injection valves: 5-7 Ohms each. With ignition on, supply voltage of 11-12.5 Volts must be present from terminal 43/1 and terminal 43/2 of series resistors to ground.
