looken to get one of these for my second gen, new motor + trans goin in, trien to keep the engine compartment clean and basic. my question is where does the one wire go? straight to the battery im assuming?

 

You can, but I wouldn't. Your question is a lot like an old folks home-- lots of depends in there. What other elect system changes are you making? Don't jump the gun and run out and buy a 1 wire alt without knowing the elect demands you will need. There are a few different size 1 wire alts. 1 wire work good but 3 wire work better and don't take much to hook up.

 

When my external voltage regulator crapped out on me, I upgraded my old charging system to a 1-wire alternator since it was easiest, and it allowed me to get rid of some clutter. I also put my battery in the trunk, and installed a remote solenoid on the inner fender. I use the solenoid as a junction for all the engine compartment hot-lead electrical hookups. The alternator jumps to the solenoid, then goes back to the battery. Works fine, and I have no regrets.

 

You can certainly run the wire direct to the battery if you want. But if you trunk mount the battery it is way better to connect to the starter.

The older style GM delco 10SI alternators are what most people use. They are plentiful and reasonably priced. However, I would not recommend using that model if your amperage requirements exceed 80 amps. The 10SI tends to build up heat and the interior components will not last as long. If your car has A/C and maybe a potent stereo system plus things like electric fuel pump or cooling fan, you should have a higher output unit. The later model GM CS130 alternators are now available in a one-wire configuration. These are rated at much higher amperage than the older alts. They are more expensive but much more reliable.

We have been buying from them for a few years now. The prices are quite good and they have an excellent warranty. Very easy to deal with.
