What does the plug for the internal regulator look like. If it is a mid 90's and up, the best thing to do is get the long Delco number off of the alternator (if it is not a rebuilt unit) and I can look up how that particular unit is wired. GM used several different regulators that look alike but they are not wired the same.
I used a Honda 5 hp to spin a 105 amp GM alternator to run a 1000 watt inverter for the first 10 hours of Hurricane Ike. It worked great to power up a couple of lights, computer and the TV.

Some of the 22SI Delco's were self-energizing if I remember correctly. You may have to manually accelerate the engine above the governor setting to get it to start charging. If it is self-energizing, you will only need to upgrade the output wire going to the battery and disconnect the input wire to the old external regulator. I would upgrade to 6 gauge wire to keep the voltage drop within reason when you load the inverter.

Some good advice on Mad Electrical site tech section. There are pros and cons to using 1 or 3 wire alternator depending on what accessories you want to run off it.

Couple more places to look or ask:

Can you post the 7 or 8 digit number that is on the alternator. I should be able to look it up in some catalogs that I still have from when I used to rebuild alternators. I didn't see many of the 22SI as I did almost 100% passenger car and light truck alternators.

You will also have to bypass the original ammeter or upgrade to a higher amperage ammeter that uses a shunt.

I don't know what size inverter you plan on using, but if it is in the 1000 watt range, I would use a smaller case alternator such as a Delco CS130 series. It would make the installation a lot easier. Millions of them were made and are readily available at any salvage yard or parts store.

The pulley selection is a lot better for the CS-130, wich uses the standard 17mm shaft, which is the size that most domestic auto makers have used for the last 40 years. I believe the 22SI may use a taper lock system on the pulley or it at least has a shaft larger in diameter than 17mm, which would limit the selection of pulleys.

The water pump bearings may not like the amount of tension on the belt that will be require to keep the belt from slipping. Most of the industrial equipment now uses a serpentine belt or two belts to handle the load.

You need to take a look at the amperage rating on the drill and the band saw you will be using. I have personally run a Milwaukee band saw with a 1000w Vanner inverter hooked up to a '85 Ford PU with the 6.9 diesel. I made one cut on a 4" sch.40 pipe, but I did not put a volt or amp meter on it to see what it did with the load. I bought a 40 foot stick at an auction and it wouldn't fit too well on the 16' trailer I was pulling. It would be best to find out what loads you will have and then find a inverter with enough capacity to start and run the load. Will you be using the tools for extended periods? The stock alternator and battery may handle the load, if they are infrequent.
