Grounds! A little story for everyone. Way back when , when Electronic Ignition was a new selling point and points were banished to history; I had a car that just slowed down then stopped. At the same time I happened to notice the stock radio got quieter and quieter until it was a whisper. Bad Alternator not charging the battery. Subsequently as it's battery charge was depleted battery voltage dropped. When available volts hit about 10 the amplifier in the radio quit, at 9 volts the HEI module quit. The electronic ignition module could not work with less than 9 volts. Excessive resistance in the ground circuit(back to the battery) would have similar effects. This is why dirty/corroded/broken strands in ground wires are bad problems and wreak so much havoc! Conversely too much voltage can be just as bad. (Though sometimes useful, overclocking motherboards in computers makes the processor speed go up but they can overheat and catch fire.)
