| 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.

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. See D22 (How can one find this ? On GenBoard/VerThree/Schematic at EC36/pin25 the keyword is "13.8V" , search for "13.8V" on the schematic drawing to find D22 ).
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. I have annotated its location on v3 picture here (inside yellow circle): |
