Not sure what the problem is! Frustrated!!

Can't figure out what the heck is wrong with my truck. Prior to relocating to the East Coast, I was having issues with it seeming down as though it were starving for fuel. Thought it was the TPI system and I got tired of it and switched back to a carb. Still had the same issues, switched back to the TPI and the truck sat for several months during my relocation. Recently took it out for a drive and still having the same issues. When it dies, it's as though the alternator (new) is not charging. I had the alternator tested last night and it checked out fine so I was wondering if perhaps is wired wrong. I have the main wire from the battery hooked to the stud, of the three wires from the pig tail, the red is also hooked to the stud, brown to the guage & black capped. Is this correct? Any other thoughts as to what the issue may be???

New fuel pump. It did the same thing when I swapped back to a carb with a manual pump. The thing of it is, it will run at idle all day with no problems but will die when I try to drive it and won't start unless I jump the battery.

Check your wiring then. Gotta be something stupid like that causing the problem. Weird that it will idle fine though...

Don't know about your wire colors but..... the lg stud wire goes to the battery, might be via the starter lug, but it winds up at the pos post on the battery,

The #1 terminal on the pig tail (white) is the exciter wire and goes to the idiot light. The idiot light gets 12v from the dash side and when the alt isn't turning and producing juice, the light gets it's ground from the internal regulator/rectifier.... and lights up. When you start the car the reg/rectifier gets 12v and it removes the ground....light goes out (no ground) and the reg/rectifier tells the alt to start to produce juice.

The #2 terminal on the pig tail (red) is the sense wire and is tied into the POS side of the electrical system and tells the alt how much juice to produce depending on the demands of the elec system, now some people tie it to the lg stud on the back of the alt, but GM originally tied it well away from the alt to take advantage of the resistance of the long wire run and get a truer sense of the demand on the electrical system etc.....

As for your black wire?????? ground maybe

Think I found my problem!! The alternator wire had shorted out at the starter. A quick splice and power's restored. Hope to road test this later in the week.
