MSD Rookie Question
I'm a guy who's pretty comfortable with wiring but no knowledge expert with MSD. Getting ready to give our 383 its first go at a fire up, break cam in, etc within a few days. This car has an MSD 6AL box. We ran some preliminary checks today and found no power at the blaster 2 coil using a test light when we flipped the IGN toggle switch. Did a little reading on MSD and found this:
Quote: One common question in regards to MSD Ignition controls is “Why isn’t 12V power on the orange (COIL +) wire?”
The main reason 12V won’t be present at coil + is because your MSD ignition is a Capacitive Discharge Ignition. Like all CD ignitions they use a large capacitor to discharge 420-480 Volts to coil + and coil – will normally be connected to ground. (That’s why you wont see +12V on coil +)
Most all stock ignitions are Inductive Ignitions, these will normally be connected to the + 12V ignition switch to coil + and coil – is connected to Points or the Factory Electronic Module. (That’s why you’ll see +12V on coil +)
So does that sound right? I should not be showing hot at the coil with test light, due to running MSD? Thanks1972 Z28 Camaro, Full Drag Car, 383 CID

on small cars yes. but fat fender cars are pretty much the same in size and weight as the donor car. i found s10 brakes work great on fat fender and pickups. a deuce will just need manual brakes...
Time for brakes
