I plugged in my JTL Versalite J-160 strobe last night. Modeling light came on fine and everything appeared to be in order until i pressed the test button. NOTHING. of the three lights on top the Indicator Recharge Ready Light is not lit. NOrmally I would think maybe the main flash tube is dead, but just a day or two ago it was working fine and the unit is only a couple of months old. Maybe 100 flashes on it. Checked the fuse and it's fine too. Anyone with similar strobe problems? Any ideas? THe obvious is to replace the flash tube but i'm rather new to these strobes and was hoping maybe it's just something i'm not doing quite right.
