Thanks for answering.
I was all these days trying to find a solution.
The truck all works fine except that the lights come on and falling needles gas, temperature, oil pressure, and other leaves to cool the air conditioning does not work the elevators.
It is the typical problem that truck, and I have a year looking for the solution, I have reviewed the wiring almost entirely, I invite you to watch a video I uploaded to youtube for some time.
1. I checked again all the wiring between the alternator to the battery and everything is fine.
2. I changed the alternator or generator by another exactly the same and the same no. part.
After these changes happened this week as follows:
Day 1: The first day there are no signs of failure, it seems that everything was fine, the volt pin 2 of the connector shown between 0.5 Volt and 1.5 Volt
Day 2: There is no sign of failure, volt pin 2 of the connector shown between 1.5 Volt and 2.5 Volt
Day 3: Start to turn lucer board marks between 3.5 Volt and 4.3 Volt. key light comes on, they turn on and off lights white board, then all the dash lights are lit and needles gas, volt, engine temperature, oil pressure, etc. are lowered the pin 2 Volt goes to 7.3 Volt fixed.
