downhill_biker Posted November 17, 2009 Share Posted November 17, 2009 So my landlord came over today to drop off some stuff and I asked her if she wanted to see the tank. She came in and I went downstairs to turn on the lights and only one was on. Then after she left I went downstairs and made sure the controller was in the right state, and that the ballast was on. The ballast makes the normal humming noise for each bulb, but I am getting no light. The bulbs are about 2 months old, but I tried another anyways, and nothing. The ballast is still humming, but nothing is coming out. Quote Link to comment Share on other sites More sharing options...
reef165 Posted November 17, 2009 Share Posted November 17, 2009 Have ya checked all the conections? Maybe one wiggled loose? Quote Link to comment Share on other sites More sharing options...
downhill_biker Posted November 17, 2009 Author Share Posted November 17, 2009 All connections are good. It is wired strait from the socket to the ballast in the basement (where it is hardwired inside of the case). FYI, this is a PFO pulse start ballast.

downhill_biker Posted November 17, 2009 Author Share Posted November 17, 2009 i turned them on, they both fired! then the one that didn't fire before turned back off... Quote Link to comment Share on other sites More sharing options...
chewie Posted November 17, 2009 Share Posted November 17, 2009 What brand of bulb? Quote Link to comment Share on other sites More sharing options...
downhill_biker Posted November 17, 2009 Author Share Posted November 17, 2009 Radium 20k, 2 months old. Lumenmax reflectors, about 4 months old. It is hardwired the whole way, no plugs all the way from the socket to the internals of the ballast. I opened the ballast just to look, and everything looked fine. Put it back together and now the other bulb is firing, and the one that was firing before, is no longer firing...this has to by symptoms for something...

chewie Posted November 17, 2009 Share Posted November 17, 2009 Did you switch the bulbs around? Quote Link to comment Share on other sites More sharing options...
downhill_biker Posted November 17, 2009 Author Share Posted November 17, 2009 no the same bulbs are in the same sockets. i did try using a couple spare bulbs that i have, but as far as the radiums, they are still the same. Quote Link to comment Share on other sites More sharing options...
chewie Posted November 17, 2009 Share Posted November 17, 2009 See if the dud will fire and stay running off the other ballast Quote Link to comment Share on other sites More sharing options...
downhill_biker Posted November 17, 2009 Author Share Posted November 17, 2009 figured out the problem. it was the controller. the first plug is wacked out and not working properly. when i opened the ballast i unplugged them, and when i plugged them back in i guess i switched plugs. that is why the one firing changed. i guess i will be contacting neptune to see why this dc8 is shorting out. thanks for the help everyone.
