No power to dash

[Baja2dakar]

Been working for several hours to try and start my LMTV 1078 after the lights got left on in the stop/light position. Flipped the power switch on all seemed normal, went to crank it and it would not crank and the power tothe dash disappeared. No alarm buzzer, no gas gauge, no voltage meter, no green light on switch. Thought batteries were dead so got new batteries hooked up and can't get the dash to come alive.

Anyone have any insight on a relay we may have tripped? Tricks to jump start these things? Thanks for any insight.

Did you check the CBs and relays?

I have replaced a load of dash wiring harness I. The fmtv/lmtv's. They are 100% crap. Lost a few due to dash fires also. If it not a fuse/relay pop the dash and look at all the browned wired due to over heating.

Did you lose dash power when you hit the crank button, or before? Do your headlights still come on and/or the brake lights work? The manual says the light switch is the only thing that has power when the master power switch is off. I don't think that leaving the lights in the stop position had anything to do with it. I have done that on mine and left it for a couple weeks before I realized it next time I drove mine. As long as the switch is in that position and nothing is pressing the brake pedal, it shouldn't drain the batteries....as long as only that top right portion is in that position, and you did not also have the dash lights on.
