I am not an electrical guy myself. My background is mechanical and knuckle dragging. That burned out item looks like a film capacitor to me. Those are also film capacitors up on the back side of the connector. If you are lucky the markings for the burned out capacitor is on the side that is...

Thank you. I just wish it was that easy. I have been studying Section 1-19 (Electrical System) of the TM 9-2320-272-10. I have found a lot of good information but not the answers to my questions. I.E. Box IDs, Circuit board, no circuit board, which vehicle uses which? etc. I have completely...

Kendelrio- Thank you for the information. That is exactly what I was looking for. My unit is not in the "coffin" box but the layout and design appears to be the same as that pictured. I have rebuilt the unit: new solenoids, new resistors, some new diodes. Post rebuild, in truck testing was...

I have seen several posting stating that The 9xx series vehicle PCB can be used on a 8xx series vehicles but the 8xx PCB can't be used on the 9xx vehicle. My problem has been that there is never any discussion on the identifying features of the two different boxes. I.E. I have several PCB on...

The truck I am interested in using this particular PCB on is a 925A2 series unit. Here are some pics of the rebuilt unit. As found condition of the unit before rebuild was the solenoid coils were frozen and had low impedance. The 48.5 K ohm resistor was reading 4.74 K ohm. One IN4005 diode...

Is this PCB a M939 vehicle box? Understanding is that a 939 box can be used on a 800 series vehicles but a 800 series can not be used on the 939. Trying to figure out if this is a 939 box. Some other 939 boxes that I have seen had a CB in the box, This one does not. It has the two...
