It's entirely possible that the electronic ignition no longer works--five out of six of mine have given up the ghost after twenty years or so.
The coil can be replaced with a 12V version with an internal resistor--and the points with conventional VW Type II points and condenser. These cars run fine with conventional points and coils.
