For no apparent reason the switch on my D2 stopped makind contact.
Replaced it and all was back to normal.
What I did find was that when the light did not shine there seemed to ber a difference in TC. Was it all in my mind or somthing else?:o
Possibly, I haven't felt any difference in my TC when the light wasn't working, I have replaced my switch a few times, the're a pain and stop working often:mad:
