'84 911 Cab, 48K miles. Battery was low and I tried to charge it and boost it (dumb.) I think I may have damaged the "brain." No spark at coil wire. Should I have the coil checked? How do you check the DME? Is it under the driver's seat? I think that one is fuel injection.

 

Checked the coil with a Sperry meter. It was okay. So I rotated all of the fuses. Not sure if what I did was the fix but it started.
