Title: Best location for rectifier
Post by: doughobbs on January 07, 2022, 10:55:37 PM
Where is the preferred/generally accepted location when adding in a rectifier (the square jobbies as sold by villiersservices etc.)?

I've no idea where the original would have been mounted on my SUN as all sorting in missing from it but I can see various potential places (some better than others! ) such as under the seat / up under the tank / in a tool box / in the headlight / bolted to the battery carrier somehow?

Does it need to be isolated electrically from the bolt/frame that goes through the middle of it when it's mounted (guessing not but after confirmation)?

Thanks!

Did they supply you with a wiring diagram, as they say they can. ?
The centre there is surely earth, but the diagram would confirm.

You can hide it away anywhere you like as the heat generated in use is negligable.
The centre mounting hole isn't internally electrically connected to any of the four terminals though many use the mounting screw as a convenient earthing point.
