HumV's are like a new
spelling word... (hang with me a second on this)
One as to see it, say it, learn it correctly, remember it and when the time comes... spell it correctly.
Learn it wrong and likely to spell it wrong, but that can be fixed.
Never learn it, don't care to, or keep trying till it looks write ahh right might work too.
Spell check I guess is the equivalent to
Steel Soldiers. Ask someone to look it up for you.
And I am not that guy to mess (different word four letters) with my buds here on SS. OK might give a little poke here in the old shop.
BUT please tell a little more of the story. "Went outside and now it won't start" isn't very helpful.
Doesn't have to read like a Dragnet scrip. Leaving out details turns into a guessing game and it not a crime, but does take up time. ( bear's a poet too)
Having fun with papakb, tobash, a tired horse, a bear and the whole gang. Now there's a story, CAMO
*****************************************************************************
OK back from a commercial break.
Still confused here.
So I have questions for YOU.
What is a dimmer in your world? I am guessing the foot switch. Not likely the problem. "FOOT SWITCH DIMMER"
Can you run the lights on the work bench? A little work, but important to know.
Does truck start and run with Lighting switch OFF?
Do you know which breaker is popping?
When adding, replacing or screwing stuff back ... any chance one pinched a wire behind a something or another part. Had to ask
There are three circuits breakers in a basic HumV rig. Two behind the gauges, one in the lighting switch (and you can't get to it easy)
At this point... they are saving your bacon
I would do the following.........
Did you remove the hood to engine harness connector and test, then report back. Didn't see a response.
Remove the light switch connector. That will clear up a lot of circuits. Maybe shorted internal somehow?? (never know)
Part of me not clear... are other systems affected or just lighting. Didn't say or I missed that part... me bad.
My last response to this was to break it down. Jump in, stick you nose in there
Sectionalizing by remove circuits so you can to ISOLATE the problem. Voltmeter in hand is handy and knowing how to use it. At least a test light probe. (not meant to be hard words
)
Schematic on bench is the road map to success.
Where I am looking to go is down a lighting circuit or engine control / run or accessories. That all for now, CAMO
Double spaced so I can think. Keep the light on papakb
directly to the 91 ground lead in one headlight.
