Help required ASAP please ! Planning to buy a solar powered trickle charger to address a parasitic battery draw issue on a 5 year old IS220D, but have concerns over the practicalities of using same. Most connect to the cigarette lighter, but this won't work because it's deactivated once the ignition is off. Some have an OBD connector (or, more specifically, is it an OBD2 ?), but as far as I know the only OBD connection is under the dashboard in the middle of a fuse panel, which is far from ideal and likely to result in problems if used regularly. The only other alternative is to use the crocodile clips, but if I want/need to keep the solar charger inside the car there'll be issues regarding the 'crushing' of the cables with the car door. Any suggestions or advice would be gratefully received, as I need to do something ASAP to overcome the frequent flat battery syndrome i'm experiencing. Many thanks.
