I can't help you other than to say I have a nice green junk yard that would accept the 1010.

Is that what that meant?
He is taking it to the yard.
No user "k" here.

-> O.P. : Can you correct that message, re-send and stand by?

In the meantime, use a digital meter if you have one, and with the truck having run for 10 min. or so, check the 14V at the batteries with:

1. lights off
2. lights on

And report the readings. this is the key to finding the trouble.

I would gladly take it off your hand if that is the ONLY thing wong wit it.....

sunday25 what does the light look like when its on.... boths lights on make a difference?

is it WHITE light or BLUE light.... could be a problem with the accumulator switch near the rear battery switch.......
I'm thinking its OP error....
anybody else??

check voltage at both alternators running and not running, check voltage at both batteries running ang not running

Oh yea the TM has all the CORRECT procedures to diagnose and correct electrical issues........

did you check the cigarette lighter voltage?

I have looked at alot of your posts on here and it seems that you have all sorts of electrical grimlins on your truck. these trucks are very simple and basic... take your time READ the TM's they will tell you all you need to know

could be a bunch of bad connections, but they are easily fixed.
