Hello, tested my 3 phase regulator today as I've been have all sorts of electrical issues.

Forward bias test read 561 consistently 3 times
Backward bias read zero consistently 3 times

I just followed a YouTube video to do this can be seen here - https://www.youtube.com/watch?v=-2jWIkhy1fo

Thing is I don't know if those forward bias numbers are a good thing for that Regulator?

Also tested the battery and reading at 12.74 v does that seem like a healthy voltage?

Pics below, appreciate any knowledge, thanks for looking.

The actual numbers are not important as long as the are similar for all three phases.

Battery voltage looks fine

Give the terminals a clean and that should be good

I would put a load tester on it but as you probably don't have one don't worry, looking at the pictures of your wiring it has already had a high load on it

Personally I prefer a Yuasa battery over a Motobatt (I don't like the connections on the motobatt)

Good luck with it Dai

Cheers for the info, ok so the numbers just being consistent is a good sign, is there static unseen workings in the Regulator that could cause it to fail?

Having a right arse about with this bike at the moment, when I should be out riding it in this nice weather.

Not going down the Motobatt route just yet, hadn't considered the Connections.

Thanks.

Yes, they can do odd things under load. I'd go with a dynamic test by checking the output voltage across the battery with the engine running. Shouldn't go over 15V when revved.
