A fully charged battery cell should have 2.1 volts. 6 cells in a battery makes 12.6 volts in a fully charged battery. Most alternators have internal regulators in them that limit charging to 14.4-14.6 volts maximum. Anything below 14.4 with the engine running and no load put on the system...

I just went through a 27MT (direct drive) rebuild last month. $125. Others have posted that buying a new 28MT (gear reduction) on ebay, the solenoid, the new bolts and the new rear mount and getting everything shipped to their house comes to about $175 or so total. Look around for a good...

Yep, everything seems to be working good. The volt meter will be right at the yellow/green line or a little below at start up cold because the glow plugs stay on for 5-30 seconds after start up depening on how cold the engine is. Then, you will hear the glow plug relay kick off and the needle...

The M35 came with 9.00-20 tires. The M34 came with 11.00-20 tires. All the major components were the same except for the tire size. So, two different tire sizes were accounted for by different speedometer reduction boxes on the transfer case. If you have 9.00-20 tires and your speedo is...

The thing to remember about a M715 compared to a FSJ vehicle is that the frame for the M715 was purpose built to be a 1-1/14 ton truck. The FSJ frames were basically for a 1/2 ton truck. Yes, I know the J30 is a 1 ton. Wagoneers and Gladiator trucks were 1/2 ton. Looking at a M715 frame and...

I have been reading about people who think a M1009 is noisy inside for years. Not understanding the problem. Could be that I think it is the less noisy Mv I have ever been in because I started out with a stock NP200 equiped M715 and moved up to a Whistler M35a2 and have the boiler room...

Colton is still home sick with a fever. It is below 100° at least now. We still plan to be there. Since Scott and White is our doctor, being 5 miles away at the Rally is better than being 60 miles away with him home for the weekend. Out of respect for others though, if he still has a fever...

The air system in the brakes only provides assist to stopping. If you have enough leg strength and your brakes are properly adjusted. You should be able to stop fine. It is just how much you can leg press. The water cooled Gasser air compressor was replaced by the two cylinder air cooled...

Are you planning to flat tow or trailer anything heavy? I loved how solid the truck felt on 9.00-20 duals pulling and flat towing. I put on XL 11.00-20's and now it is not near as stable to flat tow other M35's or a loaded trailer. That is the only draw back I have found with singles. Now...

The fuel gauge is just an Ohm meter with the sender in the tank a variable resistor. The needle going way past the F means the circuit is open. It could be the 3 legs of the gauge in the cluster, a break in the wire going back to the sender, the sender itself or the ground for the sender...

Yes, they are heavy. Figure a normal shop engine hoist will not be able to pick it up either.

You have several problems not really related to each other happening at the same time. Glow plug card issues, glow plug relay issues and then the charging system issues which cause your low batteries. Theory wise, your volt meter being lower meant all or at least more of your glow plugs were...

To put it simply, the big wire that bolts to the alternator should be 24V hot at all times. The small wire that plugs in with the Packard connector should come on and off with the power switch on the dash. If you have that, then the alternator is bad.

Go to the front of the truck and look under the bumper at the end of the steering box. The wire coming out of it is the horn ground. Move it around some. You will probably get sparks. I have had several trucks with old wiring and the horn ground wire seems to always be raw at this point. Be...

The fiber washer is all that makes the military 27Si alternator isolated ground. There is also the extra ground lug on the back of the military alternators. That make sense? If you are starting with a known isolated ground alternator, just put everything back in the way you took it apart...

Boxcar, Pistolnut and my self should be at the gate between 1800 and 1830 or at least real close to that time. For anybody coming from the Austin area, Boxcar will be whistling his way out of Red Rock around 1600 on FM 20 to 71. Then TX-21. Whichever one of us gets to the road side park on...

I figured that out after writing the above. "How did he ride in my truck when we were watching him lead the way all afternoon?"

You need to unplug the plug from the alternator. The purpose of testing with it un plugged is to determine if the problem is with the alternator or with the truck. That 3.5 volts could be from a short in the alternator or a broken wire on the truck. We don't know which at this point. Yes...

Probably the best advice is to find the -20 manual for the CUCV trucks. Click the tab that says "resources" at the top of this page. Then select TM's from the drop down box. Follow it until you find TM 9-2320-289-20. Down load it for sure and print it if you can. There is a huge 70 some odd...

May 1st until now I put: 800 miles on the M35A2 going to air shows, parades and just driving around. 200 miles on the M35 Gasser doing parades and just driving around. 1000 miles on the M715 making parts runs and just driving around. After driving 800 miles round trip to get the M1009...
