[QUOTE="ProDave, post: 470021, member: 6969"] Thanks Yes I did get it apart. It was the transistors "stuck" to the extruded case/ heatsink. An engineers steel rule slid down the narrow gap between the case and the board and a gentle tap on each freed it. This is the second time I have had this in. The first time I sat it on test for 2 weeks and it worked perfectly so went back to it's owner where it worked perfectly again for another 2 months. This time it showed the fault (alarm chirping and battery low voltage flashing) when I got it, but now it is in bits it works perfectly, so I am having fun re soldering lots of poor looking soldered joints in the hope I hit the right one and fix it.
