So this is all regarding my '70 240Z's wiring. Although most of what I'm going to ask is just going to be universal Datsun knowledge. My turn signals don't work on my 240. Hazards work very weirdly. Flash very fast, then slow down slightly. Then fast, then slow. ALL bulbs are working with no corrosion in the sockets. After running the flashers for a moment, the flasher gets HOT along with the wiring and starts to smoke slightly. Seems like a short, but no obvious wiring issues that I've found. Now something I'm not used to is this style flasher. It's a Signal stat 175 flasher two prong, similar to the canister ones I've found on later Dattos. Not sure if it's stock or not, but the car is pretty much 100% original.
Rather then having a plastic 2 prong plug like every other Datto/car I've ever owned it's got two female spades. Is it possible that this flasher could be connected backwards causing a short? Or the 44 year old flasher could just be shot? Seems to me that if there was a short in the vehicle harness it would simply just flash SLOW (since the flashers are load based) rather then fast which typically happens at low load, like when a bulb is burned out.
