Hello,
I am really hoping someone can help ne with this. I am working on this skid steer for a family member and I have ran into an issue that I cant figure out. I cant get spark to the plugs. I don't know the exact year but I believe it is early to mid 70's since it had points ignition. From what I can determine, the engine is a Wisconsin 4H4D or VG4D. It wouldn't spark from the beginning when I started.

Here is what I've done so far:
1. Changed the coil with a new one.
2. Installed a pertronix electronic ignition conversion in the points distributor.
3. Replaced the distributor with a pertronix 009b
4. Wired the coil and the distributor directly to the battery, just to bypass the wires from the switch to make sure it wasn't a wiring issue.
5. Tested the coil for power and ohms.
6. Tested the distributor with a multimeter by turning it over and checking for voltage spikes and drops.

I am at a loss as to why I cant get spark to the plugs. The wires look new to me and I have put in a spark tester to eliminate that its the plugs even though they look in very good shape. Does anyone have a clue as to what it could be?
