140 AMP alternator UPGRADE! | Chevy OBS

[@jackcobbiii1797]

How do I find the square connector mine is like yours. Is it off another truck in the junkyard of an Amazon link. Thanks

[@Projekt1]

Got it from the scrap yard

[@genelenzen]

I have 1986 Buick gn 140 amp alt 4pinsi was moving the wire on the alt and it came out of the plug now I don’t no what pin it gos to I tried the L but the volt light is not coming on should I try the s

[@Projekt1]

With the L connected, the light shouldn’t lit if its charging.

[@fallenone6]

So the bracket piece you removed is not needed? I thought it holds one of the 3 bolts in?

[@Projekt1]

No need for it.

[@fallenone6]

@@Projekt1 thank you

[@fallenone6]

So I ran into a problem. My stock alternator harness only has 1 wire going to the harness itself and the aftermarket harness I ordered has 4 wires to it. Did I order the wrong harness?

[@Projekt1]

@@fallenone6 if it plugs to your new alternator, you ordered the right one, u will just use 1 of them , the (L)

[@SilverBulletStreaming]

what slot does the old wire hook up to the new harness. is it the same pin spot on both? i didnt get one from a junkyard and the new harness has 4 wires coming off it and i know i only need to hook it to one of them.

[@Projekt1]

Connect the pin with an “L” label

[@SilverBulletStreaming]

@@Projekt1 I don't quite understand. If plugged in the old harness has 4 pins amd the wire in is pin number 2 if you count down from the top. It the only wire. The aftermarket plug i got to match the new alt has 4 wires coming out the back since its universal one. Which pin do I solder the old wire to the new harness. Pin Spot 1 2 3 or 4 if you count down from the top. Yours was direct fit with only 1 wire on both sides you just had to connect them. I got to figure out which pin to connect to.

[@SilverBulletStreaming]

Do you mean connect the wire to the pin with the "L" shape on the end. The other 3 pins and straight.

[@HODMEChannel]

@@SilverBulletStreaming Did you figure out what pin to connect to the new plug?

[@SilverBulletStreaming]

@@HODMEChannel yea it works. i dont remember what it was off hand now but the Alt is working just fine

[@hectorhuerta6436]

What year

[@Projekt1]

1996

[@tonyp3354]

what year is that? and did you have to change mounting bracket? i have a 98 tahoe and the bolts didn't match

[@Projekt1]

1996 , bolt on, didn’t change a thing.

[@tmoore4356]

What high output alternator fits lt1 ?

[@Projekt1]

Sorry I have no idea, i just look at rockauto. If your truck model was used in law enforcement , there will be a 230. What truck do you have

[@tmoore4356]

I have a 1995 z28 camaro

[@SilverBulletStreaming]

did you have any issues with the alt running since removing the rear bracket? they do have a different style you can get from the junkyard or GM but i heard it wasnt needed from reading different forums

[@Projekt1]

It has held on well since i Installed it, considering it has done alot of offroading

[@johnnymack8442]

That second battery install is cool. I assume it's a custom job you did?

[@Projekt1]

Thanks, yes custom made it

Im going to try and depin and pin the wire into the correct plug.

[@jesserousseau2481]

They really have a battery sitting on its side in the rear of vehicle?? That's so unsafe for so many reasons

[@Projekt1]

Its AGM battery yellow top, which are design to be installed in any position, even upsidedown. Been using them for decade and hasn’t had any issues

[@jamesm568]

The only modification you had to do to the 140 alternator was buy the electrical adapter and a belt.

[@Projekt1]

The belt fitted on mine

[@jamesm568]

​@@Projekt1 I've heard of people using the original belt that wasn't made for 140 amp alternator, but they usually say the pulleys end up burning up.

[@Projekt1]

@@jamesm568 I have mine for two years now. So far no issues.

[@robmora2703]

What truck did you get the wire from?

[@fallenone6]

You can buy it at most auto stores

[@Projekt1]

It was just a wire lying around at the junkshop , sorry
