I considered that option, not sure how comprehensive the wiring guide is that presumably comes with the kit.

If you're thinking of this make sure it's one that uses Mosfets, I think the Electrex one does but ask first before buying.

That's the same unit DSS sells - though both Electrex and DSS are out of stock on them at the moment.
I had thought about replacing my rectifier/regulator with one of these back when I first bought my 400F several years ago but since the OEM units were working fine (and still are) I decided to wait until they quit! :)

I fitted one of the new DSS combined units 10 years ago after a charging fault, just about limped home, thank Gawd for the kickstart!! I am not an electrician, especially when it comes to charging/rectifier systems. After making a mounting plate from an old brass window hinge, (yes, really!), the new 'potted' unit was fitted where the old regulator was sited under the left side=cover. There was just enough slack in the wiring to the old rectifier to reach across to the left side. So far, so good.
