Sure sounds like fuel starvation as you are describing. You mentioned priming and opening a tubing connection. Do you mean at the priming button on the filter at the right (engine rear) as you look in from the drivers side? That pre-filter water separator is followed by the real filter...

Your guess about freezing is probably correct. My guess is a master cylinder with some water in it. The 419 is a dual brake system with front and rear circuits separate. As you postulated, the boost system is ahead of the master cylinder and is probably fine. The booster simply assists in...

The easiest and in my opinion best load test for a battery is in the vehicle. Simply starting it. Start the vehicle while measuring voltage. Nothing to buy except a voltmeter, provides a quick load of the amperage needed to test the battery for typical use, and is usually a harder test than a...

Exactly what I needed, thanks Ron.

On the newer FMTV trucks with exhaust brakes, does the Allison lock up when the exhaust brake is applied? I have two trucks with Pacbrakes and they are great, but with manual transmissions. How effective will adding a Pacbrake work with an unlocked Allison?

A few questions for your very interesting experiment: what are road speeds at the shift points? Does the truck get into both overdrive ratios? Not having to trash a set of reduction gears has big benefits. I am interested for an LMTV I use as a daily runabout. Hardly ever loaded on only...

Fun! Makes me want to find a hamfest.

The G15000 is an awesome battery maintenance tool. Regrettably mine got hit by lightning (it was at the end of a long extension cord) and I can't find another. Does anyone know a source? My present setup is the NOCO Gen5x2, maintaining the two 12 v banks independently.

Sounds like you have some dirt in one of the two sections of the treadle valve. More details here, and how to test for the failure spot. https://steelsoldiers.com/threads/air-brake-info-and-troubleshooting.140345/#post-1900624 Post 7.

Count me in, 2 kits, if this works out. Thanks for your efforts!!!!

I remember that shack power-up trick. Might have been a Hints and Kinks from L O N G ago. Back then transmitter power might be exposed on a terminal block on the back of the chassis, the chassis might not be at ground potential (no-transformer or auto-transformer type power supply), plate...

Thank you Patracy for all the time and effort to keep this forum the best I read.

Keep up the original thinking!

Suggestion, if the "oil" looks ok, run it. Draw a sample (petcock provided for that purpose mid-engine right side frame) and have it tested (I like Blackstone). Test will probably show good to go. Saved yourself hundreds$$ !! I run one LMTV with synthetic trans lube because it was my first...

Has anyone suggested checking voltage at the fuel solenoid? Assuming this engine, 3126? Has one. Fuel can be circulating back to the tank but a defunct or stuck fuel solenoid won't feed the engine.

What I use for a second set of hands: - Need power from battery to some place? Just unroll what you need to reach, up to 30 ft. - need to activate a remote relay/solenoid, add a switch. - need to monitor voltage somewhere, attach your meter . - need an audible of when power becomes...

Well written story too! That's rare these days.

George had a great idea to listen: how about a pair of cheap FRS handitalkies, one in the truck wired to be energized in transmit when you turn on the green switch (remotely). Or slave it to the start signal but with a delayed cut-off.

Awesome work!
