New alternator, new battery ,wire to battery . the van charges when first started and charges for about 10 minutes then stops. found that if i remove the plug with the small wire on it then plug it back in the alternator will start charging again. need a wiring diagram for this truck to see were the brown wire goes or any ideas of what it could be?

Well you hit all the major ones, could be crank position sensor, ignition module, a bad coil pack (it should have 3), you need to check that you have spark to each plug while the engine is turning over (!!!be careful as this will hurt if you get shocked!!!), this will rule out coil packs. if you have no spark to any plug your looking at a bad ingnition module (which is what the coil packs bolt to). Hope this gets you on the right track!

new test just done took the brown wire ran direct to a switched 12v Conection same results. if i remove the brown wire from the 12v conection and place it back on it starts charging again
also the old alternator did the same thing. 124 amp
is the regulator controlled by cpu?
FOUND THE PROBLEM A BAD REBUILD ALTERNATOR
