Good Day: You know they are OK if you can run the gen at about a full load. If the pump tangs are free individually, check the rack movement. That's why you pull only one. The rack should pull back by a spring and the side half moon looking thing so the rack comes freely towards the front of...

Good Day: Tent stuff is also in the manuals for the system. I attached manuals the TM used to derived from. Hope it helps. On the compressor, you can MIG weld that case. Then test it if it runs and they did not drill into anything to determine if a repair is worth it. They are supposed to...

Good Day: The TM says install till it bottoms on the toothed flywheel with the tip usually between 2 teeth and back out till you get 2VAC. Uh, we found if you bottom out turn it back about 4 turns, then using dead crank as you screw it in slowly obtain your AC and snug the locknut and don't...

Good Day: I remember 151s set up with a roll bar looking thing so the CG could stand while passing troops, with cushions on those rear fenders. I just saw in German TV a documentary showing IKE, Patton, and 2 other Generals in a 151 back seat with 2 of them sitting on the fenders all hanging...

Good Day: Try this; Pick a pump to play with. Pull it leaving everything else alone. Once in your hand, I usually put the spring end against something and push it in a tiny bit and I check the little side tang movement for freedom. Then do this- check rack movement in the engine by moving...

Good Day: I attached a paper that may come in handy in the future as a quick reference. Those hoses are different than the heater hoses. As I retired these hoses were a hard to get thing and units were getting them from DRS/DHS direct. $$$$ The covers were also not in the supply system so I...

The actual use was a Power Plant (called MicroGrids) that would use multiple gen sets in stand by and start one when required and put it online to provide more power when the demand was higher all automatically and the gens were an A model using a DCSa control box. It would also remove a gen...

Good day: Attached is a color coded schematic. Try these steps...(what does the SGT say; supervisor; LAR) I am a retired P&E LAR Mater Tech or STR 1. all off and open, disconnect battery negative then positive, and with a DMM, (Multimeter) measure B+ to B- resistance. Something GOOD, almost...

Sir: Seems you get a lot of responses. Overwhelming so Ill be short in my war and peace. operators manual says L1 to L3 is your 240VAC and Neutral and ground are labeled and all as house power you are used to. You can remove that link bar or not, your choice, but ground and Neutral are...

Please read the manuals. Here is one thing I reported up the chain in about 2004. A unit had 007Bs that over revved, and others that would not shut down. I showed them what I learned 2 decades earlier when CAT put these pumps out on their new engines at that time and while showing about 10...

Oh. there is a light sequence of all those LEDs inside the DCS. You need a darker room to see all of them.

They tried to show in the manual the part of the S12 that was sticking out . I was explained to that the ON is a BIT 1 in digital electronics. I explained back Gen Mech were not in no sense of the word trained in digital electronics, so the manual can be a bit foggy. Now there were PICs of...

Good Day: Manuals, please down load them, and then use them, both operators and maintenance versions. These in the forum you are allowed to have. The latest are Distro code C you are not. I am the guy who proofed the manuals. All of them. The work packages were almost not touched. Yes...

Good day: Please do not start the gen anymore until you check out the regulator TR1 and AC Voltage adjust combinations. I attached a sheet that also allows you the check the main gen as it is not rated at 500+ VAC for very long before it kinda sorta makes lots of black wires inside. Taked...

This was as i was retiring and becoming an ECU and Gen answer man. Hid away I found TM 11-4940-483-13&P dated 1 March 1989 with Change 1 March 1997, LIW PIN 063649, it is 8.94 Megabytes large. There is also a parts manual -14&P. This was a maintenance shelter usually mounted on a 2.5 Ton or 5...

I am very glad you found your issue with AC output. I attached several PDF docs. I always use the DMM to set things as the gages are only close. You can think the gen of having 2 sides. DC is usually the engine and AC is the gen. Connected by the mag pickup and S16 and the S1 provides a...

Flop open the control panel by the half turn thumb screws on the top of the control panel. If the rope is busted fix it with any rope that size handy. Helps to save control panel items. Folks sent 2 PICs of the AUX Control panel. Right side of the control box with switches on it and an CB1...

We found a no answer means 1 of 2 things. 1- All is good. Found the issue or is using the test wire. 2. he is busy with daily life and had no time to say. because of the all of a sudden thing, I will bet a bad wire or the relay, or something happened behind the AUX control panel. Found only...

Cool! THIS IS NOT A DRASH. This is a PSI system and the issued 6 different models, and it was a combined effort done for the defunct Base X system the ARMY did away with about 10 years ago. I had to try to support this with what I am sending you. Some old guy named Dave reversed engineered...

Good Day. I'm Dave. This is gonna sound funny, any way to find out what model your working with? I'll bet I have the info your looking for but everyone called a gen trailer with an ECU on it a DRASH and there are about 30 different models and they do not all have the same things in them. I...
