Hoping someone out there can help me as I am completely at a loss for what to do!
'48 Ferguson TE-20, 12V negative ground system with a newly installed alternator, new wiring, new points, new condenser, new distributor cap, new plug wires, new coil. I cannot figure out why it is not firing. Here's what I've tried so far:
1. verified the points are opening properly and I have current through the points as it will spark when the points open, also verified the gap setting and as noted above the points are new
2. pulled the primary ignition wire from the center of the distributor and held it close to a ground on the engine while cranking the engine....no spark from the coil
3. verified I have a full 12V at the positive side of the coil before cranking the engine
4. verified that the current flow through the coil primary windings is interrupted by the opening points so that seems to be working correctly
5. noticed a considerable voltage drop at the positive side of the coil while cranking so I tested the impact of that with a direct wire to the positive side of the battery to the positive side of the coil to get full battery voltage to the coil while cranking the engine....still no spark
6. replaced the coil (iternal resistor type, no ballast resistor).....3 times......still no spark
6. battery has a solid 12V and is not weak
I'm completely out of ideas of things to check as to why I have no spark. Any help or ideas of what to do would be greatly appreciated!

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
