Hello All!!!

I just left my alternator builder, I am about to install a CS130 unit so I can play my music as I cruise up to Hot August Nights. In speaking with him on the install, his advice was to just to use one wire from alternator to battery??? Disconnect all the wire from the rear of the alternator or just tie them off close to the voltage regulator. Is this correct? By all the information that I have seen on the net and some wire diagrams of what others have done, I left scratching my head and wondering if he knows what he is talking about. That may be good on a Chevy, but a Caddy..... Easy is good, I'm thinking right would be better in the long run. Give me your thoughts.

The new alternator should have a built in regulator
A newer model design


So then he is correct?? One wire from the post on rear of alternator to battery. Nothing from the internal regulator to anything else??

I would not use a 1 wire alternator. You will not be able to get the GEN light to work.  Use a late model GM alternator and you can get a ext regulator bypass kit to get everything to plug right up.

Just got the new alt home. Thanks Russ, what you just said is more along the lines of what I have been reading. didn't wasn't to take anything away from the car, Gen Light. I will look at Rock Auto or American Wire and see if they have the kit you suggested.

Thanks much,


I put in a one wire alternator that also had the side plug. I bought the update kit from one of our suppliers that still allows the generator light to work but the voltage regulator is gone. No more room for it anyways after all my upgrades. It's a 150 amp powerhouse unit.

Very interesting indeed.

I run the SI series alternator, but wish I has run the CS series alternator. The clearance for the wire plug is in a better spot.

Lectric imited is where I got my kit from. They have excellent quality products.

Went with Lectric Limited as you Gents suggested, order is on the way as we speak. Russ it is a little bit of a pain but you can spin the rear of the alt housing to get the plug in the position you prefer.

Thanks Ron, I will have to look into that.

I can't remember but I think when I was looking for mine they could be had in most clock positions. Depended on how it was coded or serial numbered, brain fart!

They can be set for 12 o'clock, 3 o'clock, 6 o'clock, or 9 o'clock. Take the four screws off the back of the housing cover lift it and spin it to the position. It is an easier job with an extra set of hands to get all he internal contacts back in place around the armature. I would imagine there is a tool for it out there somewhere. Yes you are right about the coding, sold parts in my high school days. forgot most of what I learned. lol
