Electrical problems?

Ok so in the past 8 months I have had to change the alternator 5 times. This last time when I started the truck a noise arose and the volts droped. I drove home from work when I got home and turned the truck off smoke came from the alternator for a few mins. I replaced it all seems to be fine. Has anyone had the same prob? And does this sound normal? I'm at a loss about it. I also have the 5.9 136 amp alternaator.

That doesn't sound normal at all. Start with the easy things. Check the condition of the bat, grounds, power cables, alt harness, etc. Make sure the power has a good clean path to follow.

toasting that many alternators is a sign of wiring problems somewhere. Are the wires heavily corroded? what is the condition of the grounds? Do you have some sort of draw overworking the alternator like an amp and sub, or using a crazy amount of lights or something? Something is definitely overworking the alternator... it's possible the computer is having the alt locked on full open, but that would probably fry any battery after a single 30 min drive or two. Only other thing that comes to mind is belt related but you'd probably have killed everything else and destroyed dozens of belts if it was tightened down that much.

Ok so I changed the wires and put it all back together. Now when I turn the key to on position there's a clicking noise. When I go to start it it just cranks. No Gas smell so I don't think I'm getting fuel to the engine.

What wires did you replace? Something to do with the alternator or the sparkplug wires? I'm kinda confused by the story your posts are telling. What exactly is your problem now?

edit: I see you ninja posted. The only thing I can say is make sure you have good crimps or solder joints at the eyes of the 4 gauge wires and also make sure you haven't shorted anything out.

Lmao Sry for the ninja post. Ok I replaces the ground wire that runs from battery to body. I also did the ground that runs from the bak of alt to the battery. (It's the black box behind the alt.) And I replaced the power wires that run from the alt to the connector under the fuse box. Cut the stock connector out and put a screw down connector.

When I put the key in and turn it everything seems to get power.

Glad to hear you got it figured out. Chrysler grounds strike again, huh?
