Right, here we go. An update on my reg/rec saga. I went for an RR88 Mosfet reg/rec from Electrex World. The wiring loom plugs directly into the body of the reg/rec, which comes as a kit with the necessary plugs, crimps and seals. It's not really bike specific, but the mounting holes lined up perfectly with the Fazer bracket. However, the addition of the plugs make the body too long, so it had to be rotated through 90°. After making a cornflakes box template, it became evident that the reg/rec would need spacing away from the adaptor plate due to the shape of the Fazer bracket.
This done it was all quite straightforward. I used 14 gauge wire to extend the stator wiring, and after crimping and soldering the crimps, the colour coded plug was assembled after adding the neoprene weatherproof seals. I'd wanted to directly wire the output to the battery, so used 12 gauge twin for this, fitting a fuse holder in the positive, and soldered the ring crimps for the battery. The plug for this being put together the same as the plug from the stator.
I was quite generous with the length of wire used for extending the stator, so that if any "work" was required in the future, there'd be plenty of cable to play with.
The cheap voltage display, which although useful, was too much of a distraction, and will be replaced at the weekend, by a simple led set up, that monitors the battery performance when the engine is running or idle. This is made by a UK firm called Gammatronix and has twice been featured in Ride magazine. Although the breakers yard replacement reg/rec was working fine, at the end of the day it was sixteen years old, I think a brand new guaranteed item is more confidence inspiring.
