Jack causes diesel to stall?

Good morning,

2000 National Tradewinds 7371 with 300hp Cat Turbo Diesel

This morning, I went to use the jacks for the first time in several months. When the back right jack was going down, after it started to have load, and I believe before it was fully extended ... the diesel stalled under strain. This repeated when I tried again.

Any thoughts on what's going on?

"Strain" on the jacks won't kill your diesel engine, but low voltage will. I suspect that when your jack pump is under load it's dropping your chassis battery voltage and that's what is shutting your engine down.

Try bringing the idle up a bit. That will get the alternator output higher.

Yeah -- they need to be replaced. That's a great connection! Glad that's it!
