I bought one of these cheap as chips (under a fiver) rectifiers off fleabay a couple of years ago and fitted it to my 550 after my old original one fried. Just thought I would let folk know I am now approx 1200mls covered and all wiring and unit looks brand new. I would recommend if your not too annal about what goes behind your near side cover. I must add it was someone on here that recommended it to me.
