Where is the starter located on a Yamaha srx 250 motorcycle,(1986)?

SOURCE: ring gear spins freely in both directions when starter is remove

Very unlikely that ring gear has separated from clutch. If this model has clutch dogs on ring gear ( ring gear not permanently fixed to housing) then one or all of the tension springs have weakened and don't allow ring gear to lock in one direction.

ok now first check if you have power to the coil with a volt metre

Generally for old bikes, removal of any loom connections in FRONT of ignition coil will do it. But beware. you have no way of turning the bike off except swift removal off the plug lead. High rev use will also damage rectifier/regulator and cdi units as correct source coils have been wrongly circuited with no lights.
