Just purchased a M998 HMMWV, not new to military vehicles, but this will be our first modern-ish vehicle. These were previously owned and used, bought by the previous owner who parked them. Working on trying to get them started and having some issues.
First, I have read the owner's guide, the General TM, the Electrical TM, and the troubleshooting video and I am at a loss what I have going on.
I have civilian batteries with 750 CCA wired correctly. I have low resistance across the shunt. I have 24V to the Start Box Pins and no continuity between the light switch pin and start box pin, so according to the video I should be good to go. What I have is a solenoid and button on the dash which I thought ran a siren, but when we go to start it, the wait light is not blinking at all. I have bad ground to the screws, but when I ground the light nothing changes. I can't get the plug off to see if the bulb is bad, and I can't figure out how to get to the darn bulb. (That's problem 1)
Problem two is I have a wire marked 575A. I can't find reference to a 575 A in any of the manuals, it starts at B. Is this a ground or a hot? 575 is the start box circuit so I assume it may be related to my problem. I have the ground octupus and am installing that as I type this. I have read about a start box bypass, but this being a military tagged wire, I wouldn't think this is a bypass. Does anyone have any idea where this should go?
Thanks for the help.
