'''Problem''' Vems box is dead due to use of a old faulty battery-charger, ec36 pin25 is short to ground. (3A fused) Worked fine untill the battery-charger was connected. Melts the fuse instantly as you power on ignition key. '''Most likely Cause''' The 'old faulty battery charger' has most likely provided a much to high voltage to the ecu (>18v), there is a protection inside the ecu that trips and blows the fuse when this happens. If and large fuse was used it can permanently fuse the over voltage (transient suppression diode) device also. The rescue kit (GenBoard/VerThree/RescueKit) should have a replacement diode marked: 1.5KE18 (is 18V). If not the diode can be cut until a valid replacement has been ordered from webshop.
