2 Remove the main PCB, see "Repair procedures" [4 131]. The reactor
measuring points are ONLY reachable on the back side of the main PCB.
3 Measure the resistance of the reactor using a low ohm multi meter.
Result: The resistance MUST be as follows:
Measuring points Resistance
c 24~36mΩ
d 68~102mΩ

Is the resistance measurement correct? Action
Yes Proceed with the next step.
No Replace the reactor, see "Repair
procedures"[4169].
4 Measure the inductance of the reactor using an LCR meter.
Result: The inductance MUST be 80~100µH.
