No, I'm not sure because it's not in front of me to check it. If the reg/rec is the correct one and each wire is plugged into the socket with it's corresponding colour then it can only be correct, but if you want to check then, the browns and the greens only use the reg/rec box as a junction. The red only connects to the fuse, grey goes to the other side of the fuse and on to the regulator coil, blue goes to one side of the selenium plate rectifier with purple going to the other side of the rectifier and other side of the regulator.
Are you sure that it isn't simply a faulty battery as at 2v it probably is now.

yes it is faulty now its the second battery is there any way of checking the regulator i have a multi meter but upto now have only used it for voltage checks and continuity checks

if one of my grey hairs had fell out i would haved noticed i dont have many left tuby

The charging rates given for your model are approx. 0.6A at 3000rpm and 1A at 5000rpm, but for this a good battery should be fitted. If it is overcharging your electrolyte levels will drop quickly and when seriously overcharging will smell awful.
