Generator to Alternator

I'm thinking about updating to an alternator on my 55 Olds, what kind of modifications and changes will i have to make to get it to work properly? I heard that if it's not wired properly the alternator won't let the car shut off. Also, any recommendations on any certain year range for an alternator, i think i need at least 80 amps and would like to find one that doesn't require a plug to attach to my prexisting wiring.

 

you can get a one wire GM alternator, and run a big fat wire (with a fuseable line 4 # sizes smaller diameter at one end) from the alternator to the battery + terminal, and you're done.

 

Any recommended years or body styles to look for a alternator from? i work at an autoparts store so i have access to a wide range.

 

I dont know what a one wire would have come in originally, but they are available from the street rod parts places....

If you want to have a working idiot light, then get a 3 wire internal regulator alternator as used in most GM cars starting in 1973. You'll have to hook up a couple more wires this way....your store should have the plugin part.

yeah, 3 wires are pretty simple and a lot cheaper than 1 wires

 

I am looking at going back to a generator when I came across this. It is a little pricey but it looks right for the custom look! They are available for Fords and GM, Polished or Painted. and all one wire too!!!

...and you can pick an alternator bracket off a '63-'64 394.

 

If you use a Volvo Alternator its only two wires.
One to the battery and one from the ingition key thru a lampindikator so you get indikation when its charging. Bolte one into my 56 caddy, witout any problem.

 

what years Volvo?

 

WIth a one wire, you ball up your OEM wiring and put a tie around it, and stuff it somewhere, where you can use it again.

One battery wire from the alt to the battery.

So easy even a GM owner can do it!

 

how about if i want to run volt meter,HATE WIRING

 

You can also abandon in place the wiring for the voltage regulator and connect the alternator wire to the wire from the BAT terminal after disconnecting it. the new charge will follow the old circuit path through the ameter and back to the battery. And you'll be able to track you state of charge.
