Yeah cool. I have ordered the three phase regulator/rectifier and believe that comes with wiring instructions. In my mind it makes sense that it'll just have one extra wire. If it doesn't come with a diagram I'm sure there'll be one online somewhere
When I took the magnet off it was REALLY difficult because of how strong it was! I'll double check with the screwdriver but I think that's what I did when it first came off. Cheers for the info!
