Yes, there is an alternator fuse for a 1992 Saturn SL2. It is easy to replace and is found in the fuse box of this car.
I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.
The voltage regulator is in the alternator on that model vehicle
How do I replace the water pump in my 1994 Saturn SL2 series standard twin cam.
yes
13.5 to 16 volts.
Replace the alternator. Utilize a Hane's Manual.
bad connection from the battery or alternator
The Saturn sl2 does not have a timing belt, it has a timing chain. And under most conditions it does not need replacing.
