I had the same problem with a Trophy a while ago, the problem that you are having is the preliminary issue, after a while it will just jkeep shorting out the main 30A fuse to the whole bike.
The reg is in the top of the altenator case, you only need to unbolt the 3 nuts from the top of the case and remove the top, the reg is then in the top facing you.
You will struggle to get an original one unless it is from a dealer at a stupid cost!
Best bet is to speak to "electrex world" who do aftermarket regulators at a fraction of the cost!
The new reg will come with instructions on how to fit it.
I ordered mine and it was with me the next day!
