This winter, for some reason the Land-Rover wouldn't start. I could hear the solenoid, but the starter didn't engage. The infuriating thing was, it wouldn't crankstart either.
So, last weekend, I pulled the starter and found that the gear was sticking a bit on the shaft. A couple squirts of the dry garage door opener lubricant (it dries so it won't attract dirt) and the starter was spinning fine after re-install.
The truck would not fire. That meant time to troubleshoot the distributor and coil. The first thing I did was replace the condenser, since when they're wonky, they can test ok, and still not work. (I used the bit driver on the Cybertimer, because of the excellent reach). Testing the LT circuit showed that when the points were closed, the system still had 1.6 volts still going from the coil to ground (should be 0V). Before replacing the points, I decided to lightly file them to see if it was just some corrosion/dirt.
The shape of the SAK file is perfect to slip in there and lightly file. The Leatherman file is just too fat to get in there without prying on the points.
So in summary: For ignition troubleshooting, the Cybertool 41 is the clear winner.
