Hello from South Dakota!
In my van I keep a folder full of troublshooting guides that I have colected over the years for quick reference.
One of those guides gives the voltage at the socket for each kind of metal halide, and murcury vapor lamps. If I feel a ballast is bad I look up the wattage of the lamp and it tells me the voltage at the socket.
I have several new JW's that have a hard time troublshooting HID fixtures and would like to find this chart again.
I looked online, but am drawing a blank. can someone point me in the right direction for a web site that has this.
I found it once before, but have since lost my mind!
