wonder if anyone can have a look at what i found when i was cleaning up the wiring loom on the gs550..

Regulator seems to be non standard? it has 6 wires coming out of it, 3 yellow, one red, one green, and one black, branded on the side with ''Shindengen'' 12v regulator rectifier SU232-12 0 3.

Seems like the previous owner fancied himself as an electrician.. now still faced with the same issues as i had previously i am looking at the reg/rec as a primary concern, as it doesnt look like original or wired correctly!

I have attached some pictures, it seems to have a power feed direct from the battery, and the green cable runs straight back onto the regulator itself!

have a look and let me know what you think! Many thanks in advance.
