On the side of the wire should be a wire number stenciled on it. It should read "100xxx". What is the wire number? The first x is the wire number. The next two x's are the wire gauge. " tb4 9 through the power connector and then on the 8 " What do you mean by "the 8"? What terminal is the...

I see the admin approved your account :) The OP switch is closed when there is no oil pressure and open when there is adequate oil pressure. K20 works like this... When you have S1 in START K15 closes and the oil pressure builds and the OP switch opens. K12 the Fault relay provides 24 volts...

Wires that are on A1-1 & A1-3 are the wires that lead to the exciter. The resistance you should read between those two wire when removed from A1 should be ~ 28 to 39 ohms. Getting a megaohm reading could indicate a couple of problems. 1) Bad Exciter winding 2) Problem with wiring as is goes from...

Guyfang meant... Still holding S1 in the START position. Not in the UP position

Are the panel light bulbs good? Is the Emergency Stop button pulled out? Does the fuel pump run with S1 in Prime/Run? Is the Dead Crank switch in Normal?

With the battery(s) connected and you move S1 to Run but not START do you hear the fuel pump running? The sound in the video, was that with S1 in RUN or START? I guessing START based on the movement of the actuator arm. Correct?

Forgot the CT's are in parallel with those resistors so the resistance measured at R10 and R11 may be right. The wire that fell off was probably the problem! Bad solder joint or it was vibrating and gradually breaking the strands of the wire over time.

Did you have loads connected when you closed the contactor? If so what and how much load? Did you have a chance to check the resistance of R10, R11 and R12 with the set OFF?

Does the engine bog down indicating a heavy load before it throws the fault? With the set OFF you could try measuring the resistance of the 3 resistors. They should be 7.5 ohms.

The voltages at the burden resistors look good. The K8 Overload / Short Circuit module monitors these 3 voltages to determine if there is either an overload or short circuit condition. Overload starts to occur if any one of the 3 voltages is 7.5 volts AC or higher (133% rated load). Short...

See post #10

Get the set properly grounded first as Ray indicated. An overload occurs when the set "thinks" it sees a load of 425% on any output leg. Poor contact inside the AM/VM switch and the Voltage/Phase reconnection switch can cause false Overload and Short Circuit faults. With the set OFF I'd...

A long shot but maybe check if the MPU is adjusted properly.

Does the audible RPM jump up at the same time?

Have you monitored the output frequency while doing this? Use an external meter and don't rely on the sets frequency meter. Does the RPM stay steady? Does the frequency stay steady?

Be sure the sets have the Fuse Mod installed in them. A copy of TM 5-6115-624-BD BATTLEFIELD DAMAGE ASSESSMENT AND REPAIR How to repair and jury rig a set to get it working is a pinch. Some good info in the thread about spares Spare Parts Also if not mentioned in that thread A set of...

You ought to be able to leave a jumper across CR1 as long as needed. It's there to prevent damage to the set in case the batteries get hooked up backwards. The solar diodes will work.
