i am looking for a new alternator i am going for a one wire right now i have a stock vw alt. with the external regulator my question is i found some on jcwhitney the have a one wire 80 amp alt for $90 and a 100 amp for $129 would the 80 amp be enough do you think all i have hooked up is a cd player and headlights with my light gauges or should i go with the 100 amp thanks

yes ,,80 amps would be plenty

80 amp alternator will be all the power you need unless you are going to use a winch on your buggy.

You need to know how many watts you will have on at one time to figure out what amp alternator you will need.

I have a 55amp alternator running 6 55watt lights 3led brake lights and a 4000lb winch. I don

Hell, PM me and I will give you my number to use the warrantee and get a free one.
Just make sure you have the old one for the core.

I agree with hillaholic, it depends on your battery, you will need a good battery, junk batteries will not cut it, buy Optima. By the way,this is ohm's law, get a book on electrical engineering or look it up on the internet under ohm's law, and it will show you the memory wheel of equations, just use a calculator and you will find useful answers for your questions, not only just for buggies, but other things as well.
Here is some useful tips E=voltage, I=current (amps), R=resistance, and P=power (watts). It will also show you how voltage and current works when you wire lights up in parallel and/or series. You will see what I mean.

yeah i have to get an alt too i was looking at auto zone and they have warrantys on them so i guess ill go that rout they are around $80 or so

i am getting a new battery probably the six pack one and probably the 80 watt alt from autozone, i am going to just buy one for the warranty in the future and i can then help friends out the same way brad helps his out

Keep it clean! If there is mud on it they cancle the warranty
