Hi All
As you all know I have couple of running threads about mt 120 FOWLR build along with a bunch of DIY Projects. I received 1 of three ballasts I ordered (T5HO) from Ballast wise (the people over there are completely useless) the MH250's are MIA. Anyhow I installed it and powered up my T5's only to find one bulb not lit, quadruple checked everything including changing the bulb that refused to light and found the problrm to still exist. I called ballast wise and their first response was are you a certified electrician which I replied yes, this seemed to get him upset, then his response was to go online to obtain an RMA, didn't even attempt to help with any troubleshooting and just wanted to get off the phone, so I let him. I went back to investigate further and eventually tore the ballast apart powered it and traced out the circuiting with a scope and drew out what the output circuiting should be. Guess what, it didn't match the wiring diagram on the ballast, I rewired the output wiring, put the bulbs in and VIOLA everything lit up. Here comes the messed up part, I went to the web site and downloaded the PDF and reviwed it and found the wiring discrepancy right in front of my face (should of done this first it would of saved me 2hrs of my time). By the way the ballast is model #DXE4HO5U 4 lamp T5HO 232watt output. Trying to do the right thing and called Ballast wise back to inform them of my findings (the wiring diagram depicted on the ballast is incorrect), the only response I got from them was we never got a call like this and that they would email the boss. You cant make this stuff up.
Anyway here is the link to the online PDF, see if you can spot the discrepancy. Good luck. If you get stuck I will give you a couple of clues.
