I have a Ranger RX Speed AS and one of my heads has stopped firing. Instead of firing, it will arc from the wire around the tube to the metal reflector with a small snapping sound. I'm guessing that either the bulb has went bad or a connection has come loose.....I'm leaning towards a loose connection as I travel with the unit frequently and it gets bounced around the car and set-up/torn down quite a bit (although I am careful with it and always transport it in a padded case).
Anyhow, considering that a new bulb is priced in the $300 range, I would like to know for sure that the bulb is bad before laying down the money for a new one. I figured that I would simply swap out the bulb with a known good unit to see if the problem followed the bulb or stayed with the head. Seems simple enough but I can't figure out how to remove the flash tube nor can I find any instructions on how to remove it. Can anyone give me some insight on how this is done? I initially thought that it would just pull out but pulling doesn't seem to work (and I'm reluctant to pull too hard when I'm not even sure if that's how it's supposed to be removed).
I would certainly appreciate any insight.....Thanks!
