Going back OLD school. I have a Giesemann Infiniti 48" setup been in storage and prior to putting in storage, MH and T5 worked. This is 48" so has TWO 250W DE MH and Four T5 bulbs. Two ballasts (each one lights one set of T5 and 1 MH). I can get all T5s to work, but cannot get either MH to fire up. ANYONE still have an Infiniti that can help out? I do not recall if I should "hear" ignitors or a buzzing when starting up. I do not hear anything. I have BRAND new MH bulbs. I do NOT see TWO ballasts going bad. ANY ideas? Know fixture is retired from Giesemann but I did send out a request for help. Even schematics would be great and I can start reading voltages.
