It IS putting out a charging voltage, about 15V for a few seconds then it sees the battery as full and goes into standby.

thanks
sorry, forgot to mention...
its about a year old, used it to charge the battery of my old 525tdi BMW and it worked a treat...
its been in the back of my van for a while though and might have got a bit bashed about... doesn't look damaged though.
thanks
