Hello,
I've got a 1979 daily driver 280zx. Recently when I went to crank the engine over, as usual I did not hold it long enough and it did not start. So like normal I went to start it over again. This time as I cycled the key from Off -> Acc -> On, my voltage dropped (to roughly 3-4 volts) and lights dimmed. I ended up rotating the key all the way through the cycle and at the start position the situation remained the same.
From what I can gather, I have a component that gets power from the IGN wire on my tumbler, and then is having a major voltage drop, sucking up all the power.
Does this sound correct? I need to track this electrical problem down and if anyone has any ideas, please share them.

This maybe an avenue worth investigating. I've noticed at night, with the lights on and the car running. At idle the car will not be at 10-12 volts. Once I raise the rpm to 1000-1200 the voltage builds up to around 14+ volts.
Would that be a case of the battery not accepting the low amperage because of a high resistance or a low current producing alternator? Both are fairly new, within the last two years.
