will do so when i can get it charged. reg/rec looks fine though, no burnt terminals or anythin. can it be stuffed without lookin so?

It doesn't often appear to be knackered, you have to test it to find out.

ive tested it when connected to the harness plug but isnt there a way to test it on its own disconnected?

19 volts is way too much, thought you measure 14.2 volts in an earlier post. Battery voltage should never exceed 15 volts.

I would recommend you not run the engine again until you replace the rect/reg, otherwise you could damage the ignition control unit. It has probably already damaged the battery which is why it will not hold a charge and possibly why the battery cap blew off. A rect/reg that has a failed output control section will not usually show any outward signs of damage. They can be tested but it is a complicated process and they cannot be repaired if faulty anyway.

i did test 14.2 previously, is obviously gettin worse

14.2 volts is ok, a maximum any wear between 14 and 15 volts is normal but over 15 volts is a problem. Is the rect/reg single 5 pin plug oem type?

5pin yes

Best suggestion is to replace the rect/reg.

This is overcharging.

Dont run the bike, the battey is most likely knackered too. Also replace the reg/rec.

After a new battery and reg/rec check the stator fully.

Member on here reently had the same and didnt replace the battery, killed the new reg/rec and the ignition box

just went for a 30km ride and stopped to put some juice, bike was off for 2min and when i tried to start it just buzzed. pomp joggie push started me an when i got home i tested the alternator and the reading was 1.6ohms. haynes says healthy it should be 0.1-1.0 ohms. what would be the cause of this?
