'74 K5 with 454. Truck was running prior to beginning work. Pulled all the plug wires. Pulled the cap and noted the position of the rotor. Scribed a mark. Unloosened hold down and pulled distro up and out, noted the CCW movement of rotor and scribed that. Rebuilt distro with Summit HEI kit. Nasty inside. Sprayed some electrical cleaner inside and got all the gunk out. Replaced the weights and springs. All new module. New cap, rotor and coil. Reinstalled the distro using previous scribe marks (motor was not bumped over). Dropped right in. Plugged the three-wire connection from module to cap (red to B+). Ran new plug wires in proper order. Truck will turn over but won't fire. Now the tricky bit. Normally you'd have a tach line to out plugs on cap and a power line. I have a tach line and a line from a PO-installed kill switch. I reattached it just like it had been installed and worked previously. No start. I'm not an expert at this. Can anyone give me some guidance? Where to begin? How to test to see if I've got juice at the distro? Any help appreciated.
