I just got thru modifying a set of WebElectrics for my Challenger
so I know the circuit well.
The output transistor for that bulb is toast on one
of your sequencer modules.
WebElectric should be able to repair the unit for you.

He has been very helpful in getting me what I want and not just what they sell.
He reprogrammed my Challenger sequentials for me for free to exclude
some of the ?time-out? features......

It was a nice laid out kit but lacked the current carrying capability
of the 4 added bulb filiments. A couple of 30A lighting relays took
the added load off of the Challengers Vehicle Interface Module.
I have the CDCs in my stang and WebElectrics in my Challenger.
CDCs seem to be made by WebElectric. Or vice-versa.
Or they both have the same source for circuit boards and
vehicle specific connectors.
