Many times I've check for voltage on a circuit with out load it passed, but under load it failed. It only take two or three strands of wire to pass an ohms test or pass no load voltage.<!-/quote-!><hr size=0></blockquote>
<font size="-1">Your test light will be even less useful than an multimeter in that situation. Two or three strands of wire will show continuity, just like an undamaged wire. Depending on the gauge and length of the wire, a few strands of wire may show up as a slightly higher resistance on an ohmmeter. As an example, the original ground cable on my 782 went bad; I discovered this by checking the resistance of the cable after cleaning the ends. It had continuity, but also about half an ohm of resistance, which a 10" length of 8 gauge wire should not have. That would not have been detectable with a test light, and I was not interested in randomly replacing all of the ground and positive cables until the problem was solved.
Also, any component that is supposed to have some finite amount of resistance, like a coil winding, or field/armature of a starter/generator are impossible to check with a test light, since it can't tell the difference between a small, finite resistance and a short.

It's much easier to steer without 150 lbs on the front wheels, and since I wanted the ball far enough from the front of the tractor to allow the tractor to steer the trailer tight enough to be perpendicular to it, it is far enough forward that it would probably take a lot of weight off the rear.
If it breaks, I'll add more gussets. Seems pretty stout as is. Time will tell.
