Is there an ABC type "Idiot's Guide" to bypassing the Ballast Resistor wire?? (Eg.: A/Wake up. B/Put trousers on. C/Bypass Ballast Resistor.)
The person I bought my car from used one of those lovely little scotch block things to splice into the original wire, close to the fusebox (the other side of the ballast resistor). He ran the A&R power amp from this wire, then spliced another wire with another scotch block to run the coil. It ran like a bag of nails, and the general state of the electrics was how Sparky got his name
I removed this and did the job properly.
I had a look at the wiring diagram for my car, and found where the coil wire came out of the fusebox. Then disconnected the battery and removed the fusebox. Then pulled the fuse out, and wiggled the wire with its spade free from the back. After carefully removing the spade, I found a new piece of wire of the same size, and crimped it back in. Then replaced the spade into the fusebox and reinserted the fuse. Then I pushed the new wire through the grommet into the engine compartment, running it forwards and connecting it to the coil. Taped up the old wire with the ballast resistor in it, refitted the fusebox, and reconnected the battery.
This gave me a coil feed of 12V, from the place it was designed to come from.
Bit of a faff, but the best way to do it, IMHO
