Cyber not striking / Transformer issue

[quote=stephenwyker;39285]I have this annoying cyber that's driving me nuts; it won't even attempt to strike. I've changed the lamp, psb, ignitor, even tried connecting a known good logic board with new 14pin to the psb, so see if that was it. I am getting 120v ac on when i meter the circuit leaving the psb. Does it (or should it) jump up when it tries to fire the lamp circuit (i'm metering pre-ignitor) -- and if so, what should it be? I didn't swap the ballest or cap since it hasn't even made the bulb strike, let along not douse. :aargh4: Any ideas what I'm missing?

It is worth looking at the Power Factor Cap. If it is at all disfigured it needs to be replaced (usually they bulge out at the bottom near the connectors when they go).

If the ballast is bad the lamp will not fire.

I would also meter for connectivity the wires leading into and out of the ignitor from the PSB and to the lamp base to make sure you don't have a short or broken wire. (Obviously do this with the fixture completely unplugged).

[quote=stephenwyker;39285]Also, on another fixture, what does it mean when the green light on the psb is not lit? Usually fuses, but what if it's not that? ... Is that surely a transformer issue? I've always swapped the psb and it's usually solved the issue but this other fixture is just being difficult. I doubt its a 14 pin harness issue (as others light without that connected). Bad power2logic harness would cause a no-motor LED correct?

Generally speaking of you are missing one of the voltage indicator lights on the PSB it means that the transformer has gone bad. With the possible exception of the one for the fans which is usually the fuse or a bad fan that will keep blowing the fuse.

Which one of the three are you missing?

Hope this helps. :)
