Maybe your battery is about to fall out? You never know. Assume the unassumable.

You know it's rural people, who probably don't know 90 from 180, in a warehouse in Asia. Certainly no robots.

COVID-19
College Greek life...how could they be so irresponsible?! Completely unexpected! Who could have foreseen this? (Irony). https://apnews.com/66745a09e003a27b6c13e4578636d300 Same topic. They tried to get past the cancellation deadline but didn't make it. Lock that money in. Also learned a new word - "de-densification". It is incumbent on all of to de-densify until the virus is controlled. https://indyweek.com/news/orange/unc-chapel-hill-calls-off-in-person-classes/ https://www.unc.edu/posts/2020/08/17/shift-to-remote-cm/?utm_campaign=081720+Message+from+University+leaders+on+changes+in+the+Fall+2020+Roadmap&utm_medium=bitly&utm_source=Twitter "Given the number of positive cases, we are making two important changes to de-densify our campus."

Perplexing "FUEL" light malfunction
Not sure what you're showing. You showed a bare bulb, and the Charge warning light. The Fuel light is down lower. Here's 1976, they give more detail than 78 but it's in the same spot.

Interesting that Delphi and Spectra are out of stock. Sometimes that means discontinued.

Weren't the fuel pump companies looking in to this? Whatever happened with that? And how about those pictures? Probably got disappeared when Mike went back to the old format, whenever that was. They gotta be on a server somewhere. @Mike There's a lot of value in this thread, stopping Z cars from dying dead.

1977 280z AC -- issue # xx of yy
It might be. Worth checking. When the whole issue of the ozone layer and R12 started, some countries banned certain refrigerants and others didn't. There was and has been a lot of research going on to find new chemistries. Maybe there is a simple replacement available now that doesn't get much press, because the cars that needed it have all grown old and decrepit. The market is smaller. Also, wouldn't be a surprise to find that R12 is now legal in the US, considering the last three years. Ozone layer? Just use more sunscreen. (That's sarcasm, not my real opinion). https://www.epa.gov/ozone-layer-protection/ozone-depleting-substances https://www.epa.gov/ozone-layer-protection/international-treaties-and-cooperation-about-protection-stratospheric-ozone

Perplexing "FUEL" light malfunction
Could it be a cold gasoline/warm gasoline situation? Was it cold out when it worked right and went bad when the weather changed?

72 240Z question and mechanic in North Dallas needed
Do you think it's an engine problem or a transmission problem? Leave it in 1 or 2 and you should be able to rev it up and accelerate, without it shifting at low RPM.

AS jonbill describes, it's not what your engine wants but what will survive and stay clean in the engine. The engine will run exactly the same until the plug fouls or burns up.

Sounds like your kick-down is not kicking down. Could be at the transmission or it could be at the gas pedal.

Kyosan Denki issue
I think it might be an intentional cut to allow a bend. Looks like somebody bent the tip to get more travel.

1977 280z AC -- issue # xx of yy
I used a common cheap aftermarket radiator from OReilly Auto and it worked great. I had to mess with the mounting brackets, they weren't perfect, but once it was installed it was much better than the old factory radiator. On the AC, as I understand things, it's the lubricating oil that is the problem with changing refrigerants. You have to purge the whole system of refrigerant and oil before adding the new stuff. I knew a guy at an import shop that said he had had good results draining systems and leaving them on a vacuum pump overnight before refilling with new material. But, the system still has to be leak free for it to work. If you opened it and didn't hear the whoosh of refrigerant escaping it's probably had moisture inside and corrosion, I'd guess. Odds are against you. Funny story (now, maybe) - I was looking under the hood of my grandfather's truck many years ago when I was a kid and noticed the sight glass for the AC system. I started pressing on it to see if it would move while my grandfather was telling me I shouldn't do that, leave it alone, .... then whoosh, I got a blast of refrigerant in the face as I managed to push the sight glass off its seat. He said he didn't really use it anyway.

Are you using florescent blue coolant? Maybe your camera took some Viagra. That is a common area for a coolant leak.

You made the mistake of calling them incandescent light bulbs, instead of variable luminosity hot filament synchronization components.

1977 280Z Bouncing speedometer
You can adjust idle speed with the idle speed adjustment screw on the the throttle body. The AAR is there to hold the idle speed up just long enough for the engine to get warm enough to raise the idle speed. It's a convenience. Back in the old days we used to sit in our cars (any car) and rev the engine until it would idle on its own. If it was extra cold out we'd remove the air cleaner and hold our hand over the carburetor to get more fuel pull while someone else cranked the engine in order to start it. If we flooded it, we'd hold the throttle wide open and crank until the battery died. Then we'd get some friends or strangers in the vicinity to give us a push for a jump start.

1977 280Z Bouncing speedometer
It's very common for them to get stuck or only move a smaller amount than they are supposed to. Your symptoms match a stuck AAR. Many people just remove it and use their eye to see if it's working correctly. You can connect a battery to the terminals and watch it close.

1977 280Z Bouncing speedometer
I don't see where you tested to see if the AAR was open when it was cold. That is what will give you a high idle when cold. Open when cold, then closed when hot. The AAR also has an internal heater to heat it up.
