Alternator Upgrade

Isn't there a OEM higher amperage alternator that is direct bolt-on, plug-in for a '94 Chevy w/ 350?

Thanks,
Joey

Re: Alternator Upgrade

I think so. I think there is an 85 and a 105, actually those are both guesses. Go to AutoZone.com and type in your info and it will give you your choices.

Re: Alternator Upgrade

Yeah 85 and 105 are the stock replacement alt

You could go get a mean green or powermaster, both will do something near the 140 range or higher, also could check out a guy that goes by Dominik Irragi I think on http://www.fullsizechevy.com and see there, he does build custom ones that the users on that board seem to be pleased with.

Also it depends on what you are doing. DO you need higher amps for lights etc...while driving? DO the amps have to be high at idle for a stereo of some sort? What about winching ideas? That also plays a part in the choice of an altenator as you might also want to figure out what the current draw from accessories will be. Dual batteries + high output altenator might be what you are looking for.

Let these guys know, I know some (not alot) but enough to pass. [img]images/graemlins/smile.gif[/img]

Re: Alternator Upgrade

I do have a winch. My stereo has an amp. The stereo is not a problem. I was thinking along the winching lines.

Re: Alternator Upgrade

I'd do the dual yellow tops or red tops optima, with 1/0 wire in the mix and a min 140 altenator. Winching draws alot and I am guessing 2 batteries helps with the draw more than 1. Optima's or any deep cycle is what you want though from the sounds of it.

Just make sure the battery isolator is rated for the correct amps, and then use 1/0 battery wire to connect them up. That should be the fix

Re: Alternator Upgrade

I just upgraded my '95 Hoe to a CS-144 140 amp from this place

and it is working great. My voltmeter is back up to 14 when first started.

Re: Alternator Upgrade

Hold the phone.. There was no 85 amp option in a 1994 K truck. The options are 100, 105, and 124 amp. If you have an 85, then it does not belong in there. Post your VIN number and when I go into work tomorrow (Friday) I will let you know what you have in yours. If you have a 100, you can go to a 105. Or vice versa. The 124 has a much larger case, and is held on by bolts opposite of each other. You would need a completely different bracket to hold it on... If you need a bigger alt. go aftermarket. Its the only way to get a GOOD increase in amps.

Re: Alternator Upgrade

Why go aftermarket when you can get 140 amps from a Delco?

Re: Alternator Upgrade

I'd say spend $120 on a couple extra batteries. That will keep your winch spinning along fine. The stock alternator will charge em back up when you are back on the road. My truck has two plus I keep one in the back for the inverter or whatever. Most alt's dont produce much amps at idle which is what you are generally at when winching, ie the battery is doing most of the work. That mean green alt sounds great but at $300 or so, I prefer my $35 lifetime warranty stock alt. Its strange that the mean green only comes with a year warranty. -Greg
