Hi
I bought a used Dive Rite MR-11 canister light that was coverted by Dive Rite to an LED light head. It recently stopped working (won't light at all) and I would appreciate any help with how I might repair it myself. I realize I can always send it back to Dive Rite.
When I remove the glass lense there was a few drops of water on and behind the inner o-ring (the one behind the glass) and on the glass. Unfortunately the light was in my car 45 degrees F over night and I'm not sure if the water on the glass was condensation, but the there was a trace amount of water on and behind the inner 0-ring. There was no sign of water on the LED board or the inside of the light head beyond the inner o-ring. I couldn't see any water before removing the glass.
Attached is a photo of the LED and what I've been able to determine.
13.7 V at battery and across switch, 12.9 V at the light head measured at the white + and blue - leads on the LED board. With battery installed I took the following measurement with the negative lead of the meter on the blue wire of the LED board and moving the positive meter probe to the K and A LED leads for each LED
Lead K Lead A
LED # 1 12.7 V 8.1 V
LED #2 8.1 V 3.9 V
LED#3 3.9 V 0.1 mV
There is also continunity between the white lead (+) on the LED board and lead K on LED 3 and also continunity between the blue lead (-) and lead A on LED #1. I believe these readings indicate the three LEDs are connected in series and are all receiving power and grounded properly.
Appreciate any advise on how I can repair the problem or additional troubleshooting tips.
Thanks
