costakarl Posted October 11, 2012 Share #1 Â Posted October 11, 2012 Advertisement (gone after registration) I picked up a unit about 6 months ago but only caught up with it very recently due to a lot of travel. Condition was almost new except it was completely dead. I had anticipated battery failure and was ready to rebuild the 'akku-pack' as described earlier in this forum, but now faced a problem in the charger. Â I am no electronics technician but I am not afraid of opening things up-which I did. First discovery: a voltage regulator had sheared from its soldering and fallen out completely. With this part back in place a normal discharge/recharge was possible. unfortunately I could only get 1 red led to light. Forgetting that the thing was still plugged in an exploration with a voltage meter resulted in a plume of bright blue smoke. Curses I've cooked something. So I decided to change the capacitors in the vicinity of the smoke and lo-and-behold everything works by the book an I even have 3 red leds. Cost--about $2.

dkCambridgeshire Posted October 13, 2012 Share #2  Posted October 13, 2012 I recall that when I bought my new R8 motordrive I sent back two chargers and batteries to Leica UK via my dealer before finally receiving a third set which charged correctly. And six years on it is still working fine.  Best wishes  dunk Link to post Share on other sites More sharing options...
