Check the wire connections to the power socket on the rear of, and inside, the T41. Ours had a broken solder joint, hidden under a heatshrink sleeve, caused by the connector being loose.

I assume that you have checked the DC output of the mains adaptor.

I hope that this helps you solve your problem.

Ok.
I checked the solderjoints at Plug (male) J13 . I checked the 10 A fuse as well.

2.nd. The T41 is working from a full Akkumulator (as well as from AC Adapter)

That means "the way out is working .... but not the way in" !! (Charging).
Thats what turns me crazy.
See you --- Mirka ---

Welcome to the forums!

The circuit diagram you want is already on the forum in this thread, in post #5.

Also in my signature grab the How To's and Info doc and from there download the fuses doc. Check the two battery fuses.
