Just got a 2nd hand rectifier, and at a very cheap price! Although this bothers me... i was told it works fine but at such a low price paid im starting to wonder if it works at all.

Its a rectifier for a CBR 929 (not sure wether thats relevant or not).

Would anybody be able to tell me how i can actually test it without putting it into my bike which is currently registered off the road?

any help appreciated!
