Well I found out I had a corroded connector in the wiring at T1 terminal 2 that goes to tb4-4 and then to the voltage regulator. It was corroded between the wire and the connector itself. That was a bear to find. I swapped every component in the cubicle before resolving that it was in the wiring.

Ok, I have isolated the problem to be inside the control cubicle. I have tested the components as far as I can. By swapping parts I have determined that the vr, T1, T2, R1 rheo, and the freq transducer are good. the problem is defiantly in the cubicle. I swapped the cubicle and all these parts...

Ok, I swapped the 2 vrs. The one from my 002 into the 003 and vice versa. I still get the same problem from my 003 with the 002s vr in it. so, I tested the suspect vr from the 003 in my 002 and it works 4.0. Something else in the cubicle is causing the high voltage. When I swapped cubicles...

Ok thank you. I saw something about reading the resistance on the cvt. in the tm. I will try that while I wait for another transistor from mouser. I will probably order a few this time. I also saw a tip, maybe from you, to someone else about using something under the transistor as a heat sink. I...

Before shutting me out and locking my thread, Please consider this.... I have searched and refrained from asking this until I have read everything I could find in a reasonable amount of time. Its not like I have not tried to research this. I could just simply use a little help from this very...

I have a mep-003a that works great, but has high voltage. I swapped control boxes with my 002a and everything works great. I suspect the VR is bad but before I chase my tail for a week I thought I would ask. Is there another component that could cause this problem inside the control box? At...

wow, no replies. I only have 1 002 and 1 003. These are my first generators and i am by far no expert. I would go for the lower hanging fruit first. the valve cover is right there and since uncle sam addressed it in the tsm I would go for the valves first. who knows if some e3 or below adjusted...

Very good to know. I was checking for voltage without it running. No wonder. I figured it was like an ignition switch on a car. Thanks. It probably works 4.0 and it was just my ignorance and assumptions.

Now I get to troubleshoot the battery gauge. Not getting power at A1-4 with the switch on. Should be an easy one to fix. maybe its the relay itself. I got power to A1-3.

Wow! That did it!!!!! CR5 on the bridge board! Everything looked fine on it so I pulled it out and checked it anyway. With your help I found it. Thank you so much! now I get to clean her up and play with her. I am stoked and I learned a bunch about these things.

Im still beating my head against the wall. I see the exciter field. What voltage dose it use? I checked all my wires and they rang out good. I changes the T2 and still no dice. Why does the exciter field only work when I flash it with the switch? I hope I don't have 2 bad voltage regulators.If...

I traced all the circuits from the xformers to the diodes on the vr. I even checked the diodes on the vr. all of the connections were good and all the wires ohmed out. Then I checked the t1 and t2. t1 was spot on. t2 was supposed to be 155 ohms +- 1.55 between h1 and h2. I got 138 ohms there. x1...

OK Im still stumped. I changed the voltage regulator with one from a 003a. It still doesn't work. I can get voltage at the post only when I flash the fields. Also I noticed I don't have voltage at the battery gauge. I Thought it was the gauge at first but I got nothing in the wire. Any thoughts?

Has anyone had luck replacing parts on there voltage regulator? I see a burned diode on it. I wonder if I can just replace the diode.

RESOLVED! Hey guys, Im new on the board and just picked up my first military gen, an mep-002a. I changed the filters, oil, and drained and refilled the fuel. Got the engine running but I cant seem to get the gen set to keep power going out. holding the switch to start seems to make it work as...
