The hot battery could be caused by a lack of electrolyte.. so if your battery electrolyte was so low that you can see the plates exposed, then the first job is to top up the battery with ionised water (though frankly any water is better than nothing).
The plates should be fully covered, plus about 1cm of water, if your battery doesn't have marks or dipstick type "legs" on the cell covers.
You ideally need a multimeter. Measure the voltage across the battery terminals at rest (engine off) and at a fast idle.
The voltage at rest should be 12.6v. At fast idle (2000rpm) it should be 14.6. Anything more than 14.6 means that the regulator/rectifier isn't working.
If you don't have a multimeter... switch the lights on with the engine running and increase the revs a bit. If the lights get brighter, then that's not good news. The voltage should be consistent so the lights should not dim or get brighter depending on the engine speed.
Reg/Rec is part of the alternator. You can get just that part.. but they occasionally cost (new, AR part) more than a whole reconditioned alternator so compare the prices... It's an alternator-off job, so for the trouble/expense I'd fit a recon'd alternator (which will come with new windings and new reg/rec etc.) and have done with it.
No bullets for Chaingun..
