Hi Ronmar, I'm wondering about the batteries- will need to spend some time with them at some point, as to the scope- the noise varied and I should have done a better job at logging my tests. There is something making noise with the alternator and regulator 100% out of circuit. The biggest...

Thank you!

News! I scoped the balanced pair at the transfer case and saw lots of noise on the line when in drive. I appeared that perhaps there was an intermittent open in the output speed sensor or associated wiring. I drained the transfer case and opened the inspection plate- inside I couldn't...

Output speed sensor is around 300, it's new, Have not checked the engine speed sensor- maybe that's the problem? Also when running the TM test between the passenger side transmission speed sensor connector A&B to the connector on the xfer case 6 or 8 pin- I get no continuity, Not sure if...

I changed to original oil to full synthetic Delvac 2 years ago, filters at the same time. Cracked a cooling line this summer and lost about 2 gallons or so but it never gave me trouble after and I've driven it hundreds of miles since. I did notice that it's now hanging in 3rd when down...

Hi Ronmar, you must be as old as me! Divisions? Check out the digital results on the right for 12VDC- 4 volts peak to peak, that's AC on the DC- but also a min max- this is at an idle- the event may be fast and not on the display. I cleared the codes and they came back- 22-11, 25-16...

Hi Ronmar- I pulled the relay earlier and took a ride, it still locked out but I then had low voltage code 13-13 son it wasn't a great test. I have 3 volts of AC on the DC, the scope was at the posts in the "glove box" I ordered a new voltage regulator hoping that's the issue but it might be...

Hello Troopers! My M1078 A0 has been pretty good, 12K mi, but has developed a transmission problem. Starting out or downshifting to 2nd it will often stay in 2nd- the left range indicator blank. Shutting off the main power resets it and it will often be ok for a while. I have had codes...

Thanks for the post, I put in the two stage thermostat yesterday- works perfect. At about 75 degrees outside I drove about 10 miles before the low speed came on. Only at one point did it switch to high speed. Once off the highway and on back roads it cooled low enough that the fan turned off...

Hello Troopers! After buying my 2nd NOS, (New Old S#$t) pneumatic fan clutch that arrived missing parts from one of the military parts boneyards I started experimenting with electric fans. The first attempt failed, it was a 15" Flex a Lite rated 3,300 CFM. Too small as was the hole I cut in...

Hello coachgeo, Thanks for the tip, I called and spoke with Fred in customer / tech support. Sent him photos and a flow schematic. He's checking to see if they have a suitable replacement. I think he said they made the hand pumps for these. One thing I did learn, these system are double...

Thanks Ronmar! This is exactly what I needed- :)

Hi Suprnan, any idea of the normal pressure or volume? The one I'm looking at is 1500 or 3200 psi and 3 gal per min. I figure use the 1500 port and it would be 3/4 gal in 15 seconds. Wonder how much fluid is in those pistons. Thanks for the help. :)

Hi Ronmar. I understand the capacity, was nothing that the oem has gallons of empty tank. :)

Hello all, I'm looking at replacing the problematic pneumatic powered hydraulic pump on my M1078 with an electric powered hydraulic pump. There are reasonably priced pump/tank combos out there- It would seem a single port unit with gravity return would bolt right in, abandon the present air...
