    How does HMMWV shut down? Fuel shut off solenoid questions.

    After reading all that I have regarding this thread and IP's, here are the things I take away. 1, Stanadyne makes a LOT of IP's and they are used in many diesels. The majority of them use ETR for a reason. 2, In the PDF they show a manual override for the ETR 3, If I were ever so inclined to...

    How does HMMWV shut down? Fuel shut off solenoid questions.

    I don't think I would use that as the source 24v as it wouldn't have power if the ignition is off. I would think you would want power all the time to that switch, as Mogman said, direct from the battery. However that adds the need for a circuit breaker or fuse and if that trips, no power to...

    How does HMMWV shut down? Fuel shut off solenoid questions.

    Here's the part number Stanadyne 26922 but after a quick search, it seems to be a rare part since it isn't the standard way of doing it. Interestingly enough, you can find pictures of the part and it is the same solenoid mounted in reverse with a different lever on it. You could probably...

    How does HMMWV shut down? Fuel shut off solenoid questions.

    You would have to change the shut off circuit to be momentary or add a shut off button to apply power to shut it off. Does the alternator directly drive the ESO or would it stay running on strictly battery power?

    How does HMMWV shut down? Fuel shut off solenoid questions.

    Personally I think any quality manufacturing process is going to be equal. In my personal experience the cheap crap coming out of china is not a quality manufacturing process using quality components. A solenoids construction is pretty simple, copper wire coil, insulator, steel plunger and...

    How does HMMWV shut down? Fuel shut off solenoid questions.

    I actually looked at that one when I followed your link earlier and that one is cheap chinese crap. I did find some New OEM and some New "Made in Italy" replacement 24v 26387 solenoids on ebay between $37-95.

    How does HMMWV shut down? Fuel shut off solenoid questions.

    Thanks, I didn't recognize the M1009 number as Not a HMMWV. I don't know all the numbers of the vehicles and was assuming a HMMWV since this is the HMMWV forum. I didn't reread the thread to notice you mentioned it earlier. Sorry for the confusion.

    How does HMMWV shut down? Fuel shut off solenoid questions.

    Is yours a 12v system because that is a 12v solenoid and would be the wrong one for a HMMWV running a 24v system.

    How does HMMWV shut down? Fuel shut off solenoid questions.

    If I understand the way it works correctly, we have a ETR not a ETSO (not to be confused with a ESO). My reading of it and checking for replacement parts indicated the part to be 26387 ETR. ETR = Energize To Run ETSO = Energize To Shut Off ESO = Electrical Shut Off (both of the above)

    How does HMMWV shut down? Fuel shut off solenoid questions.

    I want to thank you for this thread, its made me learn more than I thought I ever wanted to know about my IP. It seems the thread goals have "jumped" around. ie, What if the solenoid failed? How can we start it with a failed solenoid? How can we shut it off? Can we use a valve? etc... The...

    How does HMMWV shut down? Fuel shut off solenoid questions.

    Posts with questions like these, and pictures like this, make me think of ways to solve problems that don't exist :D I downloaded the second picture and marked it up. The gist of it starts off making a new plunger OR an add on piece to the end of the plunger (the red part in the picture...
