1975 308GT4 I've got about 10.5V at the "+" side of my coils. A study of the wiring diagram reveals the following current path: Battery --> ign sw --> fuse box --> coil. Note that it doesn't go *thru* the fuse box, but busses with a couple of other connections on the top. These connections have been soldered. However, this is irrelevant, because: Voltage is fine where it *leaves* the fusebox, but drops by a couple volts at the coil. I see three possibilities: 1. Corroded wire connector somewhere between here and there. However, such a connector doesn't show on the wiring diagram. 2. Voltage drop over wires that are of insufficient size. 3. Designed resistance in the circuit. Many American cars have a designed in resistance in the "+" lead, but such resistance is not noted in the GT4 wiring diagram. A resistor IS shown attached to the "-" side of the coil, tho. Ideas?
