[DT 175 MX 12volt conversion]

Thanks NE0. The 12v AC I was getting was using the earth wire of the bulb holder but I’ll try again in the morning. I’ve tested the bulb using 12v DC from the battery and that worked ok so the bulb itself isn’t broken. As an additional test I’m going to put the 6v bulb in and test on idle, from my understanding it should light up as my readings see about 5.8v there. I’ll keep testing!

One more question from me. I’ve wired everything in and all seems to be working apart from the headlight. I can see I have 12v AC going to the bulb holder when the bike is running however the bulb I have is not working. 
 

This is the bulb I ordered: https://yambits.co.uk/12v-3535w-ba20d-headlight-bulb-p-137616.html

Does anyone have a part number or details I can use to try another bulb?

You're correct, my apologies! The forum made it look like the image links where dead but actually worked fine when I clicked.

Thanks!

Apologies for bringing up an old topic but I'm attempting this change on my DT125 MX shortly and wondered if anyone had a copy of the wiring diagram for the new rectifier / regulator? The links for me seem to be dead.

Thanks!
