This is what helped me understand how a diode works http://electronics.stackexchange.com/questions/54977/how-does-a-diode-work
I've been doing a lot of electrical and suspension work lately. 2011 F-350 with inop work lights... An hour of following wire harnesses later I found the fuse block under the rear seat. I kind of like the setup and may do something similar with the wiring in my own truck. Keep all the relays and fuses out of the weather that way.
Also worked on a Kenworth with a tach that wasn't working. The fleet had replaced the tach and the sensor but it still wasn't working. Unplugged the gauge and had 12v power and ground with a 0.2v AC signal. Plugged the gauge back in and back probed it. The signal voltage dropped off completely as soon as you plugged the gauge in so I knew I had a wiring problem. I ended up finding the wires worn almost all the way through on the back of the engine block behind the exhaust. That was interesting trying to reach in with all my wiring tools behind the exhaust.
Did an alignment for the first time this week. Pretty easy actually. Also did all the boards this week with Travis again.
Week: 50
