The purpose of the standard three-wire hookup to the Delco 12SI alternators is so actual battery voltage can be sensed AT the batteries. A one-wire regulator does not to this and senses voltage AT the alternator instead. That isn't a big deal when batteries are very close. Also, the...

NAPA tends to only carry one brand, and it's not Spicer. If you want extended life, it depends on what type of use? Some u-joints have enhanced strength, some enhanced sealing, and some both. Just about all the u-joints I've ever replaced on cars, trucks, tractors, and industrial...

Yes, and his question got well answered early on. What's confusing about further discussion beyond that? Aren't these forums about sharing information?

As I said, the plugs themselves used in HUMVEEs are designed to work properly at 11 volts, NEVER at 24 volts. I just checked my GM-Military wiring manuals for the HUMVEE. The 24 volt sytem uses a resistor that works with an 18-26 volt input, and a 12 volt output to the glow plugs when it...

Yeah? What Wellmans? Cite some actual specs and numbers. Not all Wellman or Delco plugs are self-limiting dual-coil design. Depends on part # and application. I've had more glow-plug failures from Delco and Champion built plugs then anything else. When I say Delco, I mean plugs that...

Why on earth would I call some chump behind a telephone when I have full data sheets for glow plug specs from - Beru, Denso, NGK, Delphi, May, Wellman etc.? Do you think the companies that design and build these plugs are are lying? By the way, in a 24 volt system, hardly anyting operates...

The Stanadyne injection pump does not need any other fuel pump and on some applications, there is none used. On the 6.2 used in trucks, the mechanical pump maxes at around 4 PSi and electric around 15 PSI. Anything over 20 PSI can make the pump work incorrrectly since timing advance inside...

Glow plug specs: HDS800 specs used in CUCV, also Delco 13G, Wellman G070, GM 5613939, etc. V1 - vehicle system voltage - 24 volts V2 - voltage marked on glow plug body - 11 volts A - current draw at working temperature - not given V3 - preheat system voltage - not given T3- time to working...

You are confusing "system voltage marking" with "glow plug operating voltage." They are two different things. All the companies that make those plugs post all those specs. All the 6.2 military plugs are designed to work at 11 volts, but some are marked "24" to indicate they are used in a...

All the single-coil plugs will swell and sometimes burst if used more then 9-12 seconds at a time. The dual-coil plugs have built-in protection and are what should be used for a manual setup with no controller. The Beru AC60Gs sold by Delco, and the Wellman GO50s - are dual-coil with burnout...

Yes, "506" is a later 6.5 only block.

According to the specs from all the companies that make those glow plugs, they are all designed to operate at 11 volts, regardless if civilian, HUMVEE, or CUCV. The AC60Gs are not made by Delco. They are special plugs made by Beru in Germany, and Delco and Motorcraft rebox them. 6.2 Civilian...

Here are some factory details on fuel heaters on early 6.2a, later 6.2s, and even on the Chevette 1.8 liter diesel.

Most have factory heaters I've never had a civilian diesel car or truck that did NOT have a factory-installed fuel heater. Then came standard on 6.2 and 6.5 diesel Chevys and GMCs. Same for Fords with International-Harvester diesels. They even came with the crappy Chevys with 350 Oldsmobile...

Here is the ID on the front of the engine that will read "6.2" or "6.5."

I don't recall exactly what filter-systems the military spec rigs all used, but . . . Civilian 6.2 diesel trucks to mid 1984 use the Stanadyne Model 50 twin filter system, along with a separate 100 watt fuel line heater. 1st filter has 400 square inches of filter surface at 10 microns, and...

Nope. Some 6.2s have the same block casting # as 6.5s. The only way to tell by looking on the outside is if it has "6.2" or "6.5" in the casting, on top near the intake manifold. Model year 1982 to 1991 6.2s are casting # 14022660. They use a two-piece rear main seal. The 1982 block is red...

What exactly do you want to use the AC power on? I've got several trucks with inverter systems, and my entire house and farm runs off of inverters. There are a lot of things to know, and . . . many cheap inverters are absolute junk. That being said, I bought a few Harbor Freight 2000/4000...

You're probably asking for trouble and it probably will not work except for small loads. I've got inverters in all my trucks, but . . . with all I have separate batteries with isolators. My 86 diesel Blazer has 6000 watts worth of inverters, along with an AC refrigerator that can run 3 days...

Our weather here in central NY is worse then any of the lower peninsula of Michigan. We're about even with the UP for lousiness, cold, lack of sun, snow, etc. I've got a farm in northern Michigan near the big Mac Bridge, so I get there fairly often. Like the other poster already stated...
