Rewire Ballast for MH
Hello!
I recently bought a 250w HPS/MH ballast, one 250w HPS and one 250w MH (Philips Master HPI-T Plus). The HPS worked fine out of the box, the problem is that the MH won't work and if I understand it right I have to rewire the ballast for MH. Running MH in it's current wiring I get some flickering and buzzing but even after 20 minutes, that's all it won't fully ignite.
I have enclosed two pictures of the ballast so you can see the wiring and also the two schematics I mentioned. In the first picture are both the schematics, it appears that I need to use number 2 for MH. Only I can't work out how to do so. On the second picture you see the power in and out connections.
I'll give you a quick rundown of some of the connections. Line PH goes to F on the big white box and also into the white cylinder. Line N goes into the white cylinder and also goes directly to Lamp Thread. Lamp Thread goes to N on the black box. Lamp Base goes to P on the white box and P on the black box. Finally M on the white box goes to M on the black box.
Sorry for the long post. Hope someone can help me out though, I can't start with the HPS ;)

Rewire Ballast for MH
Boy is my face red now! Just forget about my first post, it's not a rewiring issue. All I had to do was screw the bulb in properly, I guess I was a bit too gentle. But who can blame me, I didn't want to break the bulb.
