Yeah, it's not a perfect fix, but it's known to work. You can also use JB Weld, which is a more common metal-loaded epoxy in many countries.

The transmission isn't under a great deal of pressure (there is an oil pump inside it) so an epoxy type repair could probably last almost indefinitely. You wouldn't want to be using it on a cracked crankcase though, as were it to crack on the transmission, it will just leak oil, but it it failed on a crankcase repair it would draw air and probably seize.

As Roy says, the longevity of the repair will depend a lot on the preparation of the surrounding area. Brake or carb cleaner is good to use, as it evaporates and leaves the alloy very "dry", which in itself is often a good key for bonding to.

As for the electrical problem, as lam.666 says, check the battery is 100% before anything else. Then do a search on "reg/rec" and have a read up on how to test it, and all the other associated recommendations like conntectors and earth (ground) points.
