My guess is that something isn't making good contact, and that's where to start. When something isn't making good contact, picture a spark across a gap. When there's a gap, some of the voltage is lost across that gap. And the voltage on the other end would fluctuate wildly, which kicked on all of the other stuff and sent pulses of voltage throughout your car's computer system.

Whenever you have a bad ground, DC systems will bleed out. Check the voltage in your battery with a meter. If that's good, go from there and check your battery connections at their terminus.

Test the battery while the engine's not running, then test it when it is. If there's a voltage drop when the car's running, you have a charging problem. If not, you have a wiring problem.
