Thank you everyone for the help. So funny I haven't read anywhere how these can be tested in their place. Seems to me this would save a lot of trouble LOL.
My thread from a couple of years ago... Goes hand in hand with easy and simple and CHEAP and stated above by
spankybear and here it is......
> Lots of new... well old Hmmwv sales and ALL the problems (FUN) that goes with them.
Electrical issues can be a bit to chase down. Can't see them little excited electron running around. Your excited too, with a new and NOW DEAD HumV in the driveway.
To help one see them electrons and the parts energizing or not, I present this simple tester.
There's no need to stand around scratching your head and second guessing those pesky electrons and then getting sideways with fuel and pumps and filters and injectors and schrader valves on tires.
Eliminate the easy stuff with a GO-NO GO light. Good to have in your fix kit too.
Easy and simple to build. Need a light, socket for light, 9 + feet of wire (16 ga), couple of roach clips (alligator) and tape, (shrink sleeve optional). Parts right out of the junk box and a little time. See the pictures and fill in the blanks.
Socket, contact shell and pin from old tail light.
A 28 volt bulb, some wire and roach clips Ah alligator. The big red one is for Kurt. Just kidding.
The easy build, solder, splice, shrink sleeve, but no hot glue.
Now that you have it built, double check. Then the first test across the batteries. Bright light...Ya got it right.
Important note: Humv is a strong
truck... So you NEED strong batteries (both of them) and GOOD connections (all of them) to start with. (no PUN here)
Now jump ahead of the class and start answering those questions??
Do I have power to the ??? IP, glow plugs, starter, lights, heater, valve stems? Are the glow plugs in circuit or blown open. Once you get the hang of it (remember simple and easy) at home or on the trail, no more guessing.
No alligators were hurt in the building of this handy tester, CAMO
