Hi all,
Recently rebuilt a 1961 C15, as part of the rebuild meant making a new harness I converted the bike to 12v system, no problem running the bike or with the lights etc, but when I connect the stator out put wires to the rectifier it immediately begins to heat up (bike not running ) after a minute or so its too hot to handle any ideas greatfuly accepted.

check here for the wiring, as it would seem you are shorting out on the loom.

On the last link check the wiring re diodes as it is very easy to be out if it the old Lucas type.

If the engine's not running but the rect overheats only when you connect the battery across it I'd say the rect is shagged. Did you fit a nice new solid-state rect or reuse the old selenium jobbie?
