Hi guys,
sorry I don't know German language, hope english is not a problem (you can still reply in german, I can use google translator).
A friend give me faulty Led Lenser M17R flashlight and I am now trying to repair it,
I didn't expect that the electronic will be so complicated (have so many contacts with the battery).
When I test the battery with button on the "tailcap" (charging port) it shows all indicators blue and then turn off after 1-2 seconds.
XML2 led I also checked and it is OK but I do not get a light !
I tested the battery and between this two contacts that I marked with + and - I measured 6,6V, every other measurement on other contacts shows value in mV or 0V!? I did managed to measure voltage of one cell using contacts under the blue wrap (3,3V) but not the other cell, I asume it is OK because first measurements (6,6V).
Second photo shows battery contacts that go towards the switch/LED, I am not sure if I should have 6,6V on this side? I can only measure 3,02V between contact marked with - and center contact and the same voltage between - and second to center contact? If someone with good battery can measure this I would appreciate it.
Next 3 photos show pcb board with the switch (I unsoldered the switch because it was looking suspicious to me),
The side with 8 pogo-pins goas to the battery and the side with 5 pogo-pins goas to the driver side.
Everithing looks fine here, all components "sound" finde, nothing is burned.
Two photos of the driver, also everithing looks fine, no signs of burning.
I forgot to take a photo of the bottom side but there are no components there, only 3 contact pads.
I unsoldered the switch because it was looking suspicious, it has 4 legs, 2 were looking normal and other 2 were shorter as if cut off slightly.
If you have this switch I would appreciate If you could let me know what continuity pattern do you get in each of 2 positions, I measured this:
Position 1: pin 1 and pin 4 are in continuity (shorted), no short between any other pins combination.
Position 2: pin 1 and pin 3 are in continuity (shorted), no short between any other pins combination.
It looks like pin 2 is not used, strange! or the switch is faulty?
Sorry if photos are too large and thanks for any hellp you can provide.
