Sounds like your regulator / rectifier has gone. or the 2nd one your garage blokey put on is as f*cked as your first one was.

Personally I wouldnt bother with ebay, I know it sounds cheaper but how do you know that the one you are buying is working.

Bite the bullet and buy a new one... do a search as suggestion this has come up loads of times, theres a thread somewhere from Sid Squid that advises how to check if the bikes charging properly.

I doubt its the indicators that are causing your problem. Mind you it might be worth getting the wiring checked by somebody who does know what they are doing.
