Testing neutral battery cable, crank and camshaft sensors for ground, wire connectivity, etc.?
After changing my timing belt, key won't crank the engine, dash lights flicker sporadically and positive battery terminal warms significantlly. Also, fully charged battery drops from 13.5 to 12.4 volts. How can I use my digital multimeter to test the Neutral ground, camshaft and crankshaft sensors?

Put it on the Ohms reading, lowest setting. Touch the leads from the negative side of the battery to the engine and also the body.. Should have less than 5 ohms. To test the positive side you have to go to the starter and battery. To test the sensors your meter has to be able to read hertz. Put the leads to the positive and signal return. Tap the end of the sensor with a piece of metal(screwdriver, wrench) rapidly. It it reads any numbers, it is good.
