Is it an automatic or manual? Might not matter but good to know. If I had your problem I'd probably try to lever the starter away from the ring gear while I tightened the starter bolts. Crude, but it seems like the starter gear teeth aren't fully engaging with the ring gear. Maybe the wear on the ring gear teeth is enough to finally cause binding, from what was a tight tolerance. Actually, an even simpler quicker test is to loosen the starter bolts slightly so that the starter can move away when actuated and let the teeth mesh. It should be fine for a few starts as a test. If it works you'll know that you have gear meshing problem. Edit - do you still have the old starter? Take a close look at the teeth on the drive gear. You might find that they've not been fully engaging in the past. Might be a clue.

It's a 75 280Z. I wonder if the rest of the car is similar. That is not a typical rust area, to that degree. Might be best off to find a new shell and move all of the good parts over. https://www.classiczcars.com/profile/35466-ennisdavis/

Has it ever worked for you or did you just buy someone else's problem?

Facts only mean so much but here are some. https://www.cdc.gov/flu/about/burden/past-seasons.html Looks like 510,000 for the first full year of COVID-19. We're at 127,000 already at about 6 months in to the second year. https://ourworldindata.org/covid-cases

Found a web site. Who knows? 436 Euros for the top piece. http://www.autospares.eu/search.html?search=search&article=66300-N4700&term=0&sort___search_results_by=final_price&chk_smode=on&smode=A http://www.autospares.eu/price-lists/nissan/2568/

I didn't narrow it down, just found the part shown and posted a starting point. But, since you brought it up... http://www.carpartsmanual.com/datsun/Z-1969-1978/body-260z-280z/2-seater/cowl-top-grille

Use this to figure out which wrecking yard cars to chop up. http://www.carpartsmanual.com/datsun/Z-1969-1978/body-240z/cowl-top-grille

If you go with ground control then any short circuit in the wire between the device and the control relay will power the device. If you have power supply control a short will blow the circuit's fuse instead.

Type A definitely looks different than type B. I really don't know much about either. I did find your part number under the Sports pages though. You probably did too. You might see if there's another old Datsun forum out there somewhere. Your idea of trying a 1.0 mm shim makes sense. Can't hurt. Might be the guy before you was in a hurry or just didn't have the tools to do it right. https://www.carpartsmanual.com/datsun/sports-1965-1970/power-train/transmission-shaft-gear/5-speed-(warner)/20 Here's the link that you copied the numbers from. http://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/transmission-gears/4-speed/to-aug-71 And for those who want to see the change... http://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/transmission-gears/4-speed

I've wondered if the broken magnet was a show stopper. Apparently not. Make sure the blue wire is connected to the negative terminal. It's Pin 1 trigger to the ECU for the injectors. Counts sparks then opens them up.

Lots of good stuff on this page, linked below. Menu down and to the right. Not many ZX's here. @dutchzcarguy has one. https://www.classiczcars.com/files/

What are the issues? Might just be the module. You can wire in a GM HEI module for about $25. Or buy a ZX module for $134 (ouch). The HEI module will work as well or better. You could also convert to a 280Z distributor if you happen to find one. https://www.rockauto.com/en/catalog/nissan,1981,280zx,2.8l+l6,1209338,ignition,ignition+control+module+(icm),7172 Here's a detailed, make-it-look-right example, but you can also just extend the wires out to the fenderwell.

Here is that recent thread.

Which ones? There are six. Here is the info from the Nissan Factory Service Manual book. There are shops that know how to make the propeller shaft joints replaceable but it's not standard practice. somebody just posted about it.

Really seems like the guy is just having general problems running his business. All signs say avoid Whitehead Performance. It's been going on for a few months. Go to April 10 in this thread if the link doesn't get you there. https://forums.hybridz.org/topic/113706-whitehead-performance/?do=findComment&comment=1228704

This would make a good addition to the Wiring Diagrams Downloads page, and a few other places. Documents can exist in more than one place, I assume.

Bad bleeders bud. Bummer. New MC maybe? Yours seems oddly shaped. Where did it come from? Looks it might even have ports, or the bosses for ports, on the other side. Are they drilled and tapped? Maybe just swap them.

Any chance you have a motor mount problem? I like to browse around the BAT site to compare to other cars. They take a lot of pictures. I took a few looks and it does seem like they have more room than you do. Here's a 71. https://bringatrailer.com/listing/1971-datsun-240z-187/ https://bringatrailer.com/datsun/240z/?q=240z

Sounds like your L wire is not providing power to the windings. Check for voltage at the L wire with the key on. A good alternator with no L power will not charge. Actually with an external alternator, it's the F terminal. No F power, No F'ing charging. Check inside the plug with the key on. sometimes the connection canget loose too, so if you find power make usre it's a solid connection to the F terminal. Check your grounds also. The alternator case should have a ground through the monuts but it also has a dedicated ground wire. No ground no charge.

He's getting inexpensive publicity for his art stuff. The Pitchfork headline was funny, I thought. Nirvana sued by baby... The guy should have a baby chasing a dollar tattooed on his chest. And how about a new headline - "Baby still chasing dollar".

Use your door buzzer circuit and switch as a "headlight on" buzzer.

The only draw on the battery would be the clock. And that is so small that it won't drain a battery for months. Still not really clear what problem you're trying to solve. You showed that the alternator is discharging while the engine is running, which means the alternator is not working. That will drain a battery pretty fast, with spark and fuel pump and various relays drawing power. A super simple check for a key-off draw is to watch and listen for a spark when you connect the last battery cable. I had a single relay active after a wiring change (alternator modification) and it created a significant spark, it was a clue that I had a problem (along with the battery dying overnight). I think it was drawing 0.3 amps. Once I fixed the draw even the clock didn't produce a significant spark even though it worked just fine.
