is this a ruff idel or bad grounds or maybe gm alt is a couple degrees off on mounting position it has always done this since i changed alt but sometimes runs sweet and gives a constent 13volts usally when drivin 60-70mph

 

Have the alt tested at a parts store.

Is the belt in good shape, does it slip.

 

Check the alt with the car running. " ...sometimes runs sweet and gives a constent 13volts usally... " sounds like you need to explore some better alternator solutions.

 

but the alts brand spankin new the belt dont slip plus it never squials and is also ony 3weeks old

will idel not affect the alt?

 

Not that much, and with a stronger alt it should be less so.

 

im pretty certian that its wired right aswell ill get it tested tomorro arvo

not a ground issue? my drivers headlight it dimmer than the other thats new to me
at night my cars a moving disco light

alt set a lil bit of an angle to the main pullys? im sure wouldnt cause this

 

It's not unheard of the get a bad one from the store, get it checked out, and try to fix that mounting angle, it will wear out belts leaving you stranded.

 

Alt should be putting out over 14 volts, something is wrong.

 

well thatl be pissing money into the wind if its malfunctioning*spelling*
since i grinded the mounting ears be no refund

 

Run a couple of extra ground wires from the motor to the - on battery and from the body to the - on the battery. Just rig something simple to check it out.

 

Can you swap out the housings?

 

iv only got thin 12gauge wire should i use somthin thicker
its a good idea and worth the try

 

by this what do you mean im lost on what your refferning to chief

 

The alt housing, can you swap them when you buy the replacement, if and when yours is bad.

 

ohhohh i see now smart aussie
ill find out tomorro im not sure

 

Just give me a pat on the head every now and then and I'm a happy dingo *******.

 

Using the 12 gauge wire should be good enough for a short term test. If this solves your issue then you can get something more suitable later...

 

hehe goddamn you admit it
well we gotta get the sheep out of the fence some how

 

what, did you get it from autozone? Do you have a digital volt meter? My friend just went through 3 alts trying to get ONE that works from the zone.

 

If nothing else, take it to a shop that rebuilds alts and have it done right. They can test the output too.

 

I have three bad ones here, time to learn how to DIY I think.

Yeah I'll admit it, but pickings are slim in Ohio.......lol

 

hmm thats kinda shitty do they usally get regulator faults?
last time i tryed diy i broke it and shorted it lol i couldnt get it apart wrong tools
i brought it from kehtch's autoparts i cant rember how its spelt 120bucks was good at the start
i have multi meter what should i check for excsatly?

 

I bought a brand new alternator for my Dodge, an AC Delco. It failed less than 3 months later. Sometimes you just get a lemon.

 

well today we tested with the alt things
and found it was charging but amps goin all over the place goin from 10to40to -9 all over the place
colpurt was the wire bat+ from the alt to the fuses i bypassed from the bat to alt hand got a constant 40amps the gm alt puts out 13.55 volts it surges less than before
might be idel
also discovered that my coil was bung and got a free replacement hehe they know me well at the autoparts im there major customer

 

That's cool man, glad it wasn't the alt after all. Time to go through the whole system and replace some/all of the wires, hey was that a dingo?
