Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially and on "...is there MASTER CIRCUIT BREAKER AND IF SO WHERE IS IT...", I don't recall a 95 to still have a circuit breaker but if it would, it would be behind/near the fuse box. A way to determine if indeed no circuit breaker on your version would be the existence of a 25 or 30 Amp fuse in the fuse box. And the alternative would also hold true; no 25 or 30 A fuse, then there would likely be a circuit breaker.
Have you tried starting with the side stand folded up and the clutch lever pulled in?
Still, proposed preliminary checks (if have not been tried):
Additionally (and again if have not been done), re-inspect the battery, its ground lines and/or re-check and re-clean the battery cables + terminals, connectors and wiring. In some instances, it may be an advantage to hardwire a secondary ground BUS; i.e. from the battery's - terminal to the frame, to the engine and to the harness' black wires.
