[Should I save it or move on?]

Agreed. If the passion still there for this kind of car, then make it as a project. But you have some hesitation as due to the condition needed to work in the car, then i must say... move on as the passion is not the same.

Why not try to consult an auto electrical services. Anyway, have you tried to check the connectivity directly to the battery or you may use tester device by checking it connection from end to end.

[The E-Charger. What do you think?]

Interesting.. Less fuel and provide more power as the normal gasoline engine. The question i have in my does it will take longer as the normal engine? meaning the life of this echarger in terms of cost wisely in long run and can we still have the option to use the normal gasoline in case of out of charge while driving? Those questions i have in mind right now.
