Good afternoon guys, i'm having a problem with a GENSET, I can apply power with my power probe to the actuator and it works like normal and sends fuel through the injection pump, however when I reconnect it to the P10 connector plug I get NOTHING. Can anyone tell me where I can trace the wiring back to find where they originate from so I can see if there are any further faults somewhere for the non voltage getting to the pump from it's actual wiring.

Screw magnetic pickup (4, Figure 4-30) into flywheel housing until pickup bottoms out on flywheel. Back magnetic pickup out 1 1/2 turns. Tighten locknut (5).

Adjust magnetic pickup (4), 4.13.3.d.

Set multimeter for VAC, and connect multimeter positive lead to terminal B of P13 and negative lead to terminal A.

Set MASTER CONTROL switch to ON and crank engine with DEAD CRANK switch. Observe
multimeter. Indication should be between 2.0 and 3.0 VAC*

If indications are not as above, back magnetic pickup out 1/4 to 1/2 turn. Retest by cranking engine and observe multimeter voltage.
