Thanks for all the advice
I’m not sure which bit of the DX light has failed, its between the battery and the charger I think, as when its plugged in the charger light goes green instantly.
The main reason for going DX again was to be able to reuse whatever components were still working as spares.
I’m hoping its the charger that has failed so that when I buy replacements I’ll have a spare light unit and battery.
It looks from the pics of the light and go site that they use the same cable fittings as the DX, can anyone confirm that?
