Didn’t want to high jack Bob’s thread;
This is what led me to the decision to not jump it with my work truck. This is from a discussion on redpowermagazine;
“You say it had a bulge on end of glow plug. That usually comes from high voltage. High voltage is generally caused by using a battery charger while cranking or even a jump start from another vehicle that is running. In fact, I never press glow plug switch while running after I have let loose of it. The glow plugs ordinarily draw enough current that if you keep them on during cranking and after it first starts, which you should do until it clears, your charging system will not be able to charge enough to cause voltage to rise above acceptable levels for the glow plugs. I have seen many glow plugs, spanking new, burned out right now when jump starting. I have no idea what make your replacement glow plugs are but even the IH factory ones are extremely high voltage sensitive. A normal charging voltage of 14.5 can and will burn out glow plugs. Now, if you happen to have an alternator on that machine, it will probably put out enough amperage, even with the glow plugs on, that the voltage can rise to high levels. Original generators were only 35 amperes and glow plugs draw more than that so voltage would not rise high enough to hurt glow plugs if you kept them on , BUT , you could burn them out if putting them back on after engine started and ran a little while. Just a suggestion.”

Although I have, on occation jumped it with the Ford 3930 which also has the alternator “detuned” to 11 volts + /-.
