I have no idea what to do to next! I have a new battery, cables, alternator and voltage regulator. I have checked each wire in the harness with meter and I also have tried to make a wiring harness as well. I have checked every wire and ground on the truck. I have taken the alternator and had the parts store replace them and had them tested 3x in the store and the part is good. I am not getting anything and running off the battery. What is next after the wiring harness, grounds, battery and I checked the fusible link also. I have (field- Orange wire) going to F on regulator and (S) ( Have Gage ) going to a green & Red wire "Ignition". (A) going to bat (small yellow wire) and a Ground to alternator to ground on voltage regulator. I don't think I am getting the alternator to turn on? I have tried every wiring possibility with regulator. has anyone else had something similar happen?

 

If you look carefully, you'll notice that you didn't actually state what is wrong with the vehicle, other than that there is a "charging problem" which is an assumed cause for symptoms for which you have yet to describe. Saying that you're "not getting anything" is ambiguous. Not getting any what? Satisfaction? Saying you "checked every wire and ground" doesn't tell me what you actually did. Only numbers measured on a multimeter mean anything with electrical systems.

What's actually going on? Are you measuring a sub-standard voltage? The truck is slow to crank? Dies after driving? Please start over and fill in all the blanks. We're here to help you, so you need to make that process as straightforward as possible.

 

When did this start happening? Did the truck just not start one day?

And can you "try every wiring possibility to regulator"? I dont understand that, can you wire it more than one way?

 

Truck cranks and runs as long as I don't run head lights or heater fan
Truck alternator is not working. What I have done to fix the issue:
1. Replaced alternator
2. Replaced battery
3. New Voltage regulator
4. Checked all fuses
5. Checked continuity of each wire in harnes
6. Checked ground wires on truck and alternator
7. Checked voltage on each wire

I am only getting about 11v.

The problem:
Alternator is not working

 

I drove truck and once it was dark I cut the head lights on and it would not crank back up after I turned it off. I wired the regulator with the stator and with out stator.

 

I may be wrong, but would pulling 1 fuse at a time, checking voltage, then putting it back, pulling the next....would help isolate a draw?

 

No, the problem is that the truck won't run under electrical load, and the charge voltage is low. The alternator not working is what you suspect to be the cause. No one can know that yet. According to you, the alternator was tested on three separate occasions.

Please stop experimenting and trying random different wiring configurations, as that will only complicate the issue and add variables. We're going to walk through different points in the charging system. First off, does this truck have an ALT light, or an ammeter in the dash?

 

I know the alternator is not working. It's not turning on

 

I have the meter in dash

 

Ok, sounds like we are done...alternator is not working

 

I had the alternator tested on the truck today and it is putting out "0".

 

I don't think my point is coming across.

Disconnect the voltage regulator, and measure the following voltages:

1) Terminal on the truck-side connector that would go to the 'A' terminal of the voltage regulator, relative to ground
2) Alternator output stud, relative to ground
3) Across the battery posts

All three should be equal. Next, turn the key to RUN and measure the voltage on the truck-side connector that would go to the 'S' terminal of the voltage regulator. This should equal the previous three measurements.

Report your results. Your next response should consist of four numbers.

 

I tried that and got the same reading of 11v

 

11 volts for all four numbers?

 

Yes, there was no difference in truck running. The same as if it were off
