inside humvee HMMWV start box eess humvee

The protective control box has been a point of contention for over 50 year. Just about all Army wheeled vehicles had a version of this box on-board. Back in the day they were manufactured by Leece-Neville. My Fuel & Electric guys took one apart 40 some years ago. The only thing serviceable was the relay. The logic PCB's and terminal boards had no NSN's assigned and the Army Tank-Automotive Command never provisioned repair parts. The entire box was designed as a line replaceable unit. The Protective Control Box was designed to protect the cranking and charging systems from catastrophic failure.

Thanks for this … can you just make a new harness and connect directly to 24v. LeAve the original boots for the flow plugs unplugged? I hate to spend $1000 on a box for it to crap out again.
