Acquired a Datsun 2000 that has been in storage for 12 years. Starts and
runs, but the battery will not charge. The battery is wired positive ground!!
The installed battery was dead beyond recognition. Installed a new battery
the same as the original was connected. Starts and runs, but how can it
possibly charge if the battery is wired backward? Didn't the auto industry
convert from positive to negative ground in 1954? So some idiot installed
the battery wrong. Interestingly, the grounded cable is RED.
OK, as I thought. It is a negative ground. Some dunderhead used a red cable for the ground and a black cable to the starter solenoid, then some other idiot installed a battery according to cable color. What is worse than one fool? Two fools! Fortunately, no electronics in this car to be fried by reversed polarity.. Starter worked because the motor doesn't care about polarity due to how it is designed. Alternator didn't notice 'kuz a mouse ate the alternator wires.
