How do I test this before installing it on the bike. i am replacing the electrosport regulator that I bought 15 years ago.

Don't know how to test it, but if it really is an SH775, it is a series regulator, not mosfet. Series is what you want though.

Yep
The SH-775 is SERIES based on an SCR design.
The Compufire is SERIES based on a MOSFET design
What people call "MOSFET" is SHUNT based on MOSFET design.

Modern regulators such as MOSFET and SERIES R/R's have a micro controller built in to make the R/R operate. It is hard to test without having the 3 phase AC excitation.

The tests in the manual are only for old style (SCR SHUNT) regulators(including Electrosport, Ricks, Honda, most of the chinese stuff you see) and do not apply to anything new.

Yep, that's the good series R/R.

check the partnumber to be sure; it should say SH775XX

My GS1000 has a 15 A main fuse. would it be safe for me to wire this to my battery using 12 gauge wire and a 20A circuit breaker?

If by "safe" you mean, will not melt any wires? Then yes you are OK, but I would not recommend it.

Hmmm.... did you buy it from a pukka Polaris dealer, or just some seller on ebay who quoted the Polaris OEM part number?
If the latter, it's probably a fake.
<edit>
I just noticed you said in another post you bought if from Motosport.com - in which case it should be genuine.

If you are blowing fuses you probably need to clean the ignition switch and then stay with your factory fuse size.

Best to stick with original layout- study this explanation to understand why.
