Duffy's 1/71 Series 1 240z build
Well the headlights should be drawing less than 10A total (probably around 8-ish), and all the running lights should be at less than that. I'm thinking you should have been around 15A plus whatever the battery was pulling. Maybe the battery was pulling a bunch? I'm thinking maybe the batter was partially discharged since it's not getting a lot of running time? You running the heater fan and defroster too maybe? Just seems odd to me... Most times I don't see an alternator needle swung that far over. Now of course, I've got the voltmeter on my later 280, so what do I know? What say you 240 guys? Does it seem odd to see the alternator needle swung over that far?

Work looks great and I'm no engine expert, but I wouldn't be too concerned with that range on the compression results. Certainly nothing that you would need to address in any hurry. I do have a question about your alternator output though. That looks like a lot of charging... Does it make sense for your alternator to be pumping out 35A under whatever the drive conditions were at the time? Seems like a lot to me.

Haha! Not intentionally. I don't think I've ever seen it. Is there a line like that in there?

1973 Rebuild
Here's a pic of what happens when you try to press a bearing in at an angle. You can see the semi-circular mark on the far side where they gouged the cylinder wall that is supposed to locate the bearing. That raised bump was pushing the bearing to one side and not letting it seat square. I used a hand file to dress the high spots back level. This pic is about halfway done. I considered using a dremel with a small grinding wheel, but last thing I wanted to do was slip. It took way longer doing it by hand, but I wanted the control that I could not achieve with a power tool:

1973 Rebuild
My pleasure. Glad to help. So did you see the pic of the aftermath of the party? https://www.classiczcars.com/forums/topic/60026-friends-over-for-a-party-in-the-shop-yesterday/ So to provide a little more info about Matthew's bearings... The shop that had previously worked on the car really screwed things up. They had forced the spindle pin tapered retainer pins into place without having the spindle pin located properly. This not only ruined the taper pin, but raised a huge burr on the (brand new) spindle pin and we had to use the hydraulic press just to get the spindle pin out. And the problem that Matthew originally noticed when he got the parts back from the shop was that the stub axle didn't spin freely, and had significant tight and loose spots when it spun. We traced this issue to a huge burr kicked up inside the strut housing on the bearing surface from them pressing the bearing in cockked at an angle. In other words... It wasn't straight, wouldn't go in, and they just kept applying more force instead of stopping to figure out what the problem was. We dressed the upset material (high spots) off the inside of the strut housing and cleaned and inspected everything to make sure there weren't any other surprises. Once the burrs were removed, the new bearings went in fine and everything spun perfect. We dressed the burrs off the spindle pins, and after that, they went back into the housings OK as well. And if that's not enough... They had ground down one of his distance pieces on a belt sander. Not only was it not square on one end, but it was also now almost .100 too short. When you tightened the stub axle nut, it would pull the inner races together so tight that you couldn't turn the axle. And they're professionals!! I chucked up the distance piece in the lathe today and squared up the end. Won't ever be able to be reused for a distance piece, but it sure makes a handy drift for doing future wheel bearings. Into the box of misc stuff that lives next to the hydraulic press! It was a good day in the shop.

Wiring EU Taillights/TS Problem
Well I consider the term "butcher" a little extreme... I was suggesting that there may be a possibility to "modify" the wrong harness to "convert" it to the design you desire. With the right tools, you can remove the electrical contacts from the plastic shell and then re-insert them without damage. I was thinking there might be a possibility you could do that to the harness and end up with what you desired. Take the part number label off (to avoid future confusion), and use it on your car. I know the chances of success of that plan the be very small but non-zero. Thought I would toss out the suggestion. A good condition (but wrong) harness isn't worth as much to you as one that does what you need.

Craigslist Scam
Steve, Well that's definitely the same car. That for sale ad on Hemmings looks legit. Someone probably just copied the pics and started scamming. Zed Head, The craigslist ad is already gone. But curiously... It doesn't say that it was flagged for removal. It says it was deleted by the author. I've corresponded a little with the scammer already, and I've considered sending them another message and stringing it out some, but I just have the interest. Unless someone has any good ideas, I'm just going to let it die.

Haha! I should have put out an open invite, huh? Would have loved to have you over too! By the time we got to number four strut, it was "almost easy". Once you figure out the best order of events and which spacers, drifts, and little bits and pieces to use... It's almost assembly line.

Darn right. It was epic! Two more Z's with tight new rear bearings headed for the road soon!!

Bringing a 1977 Z back life
Well then that's extra awesome that was truly the first real start. Great work! If you want, I'll look in my box of stuff for a TVV. I've switched over to a completely different throttle body and I don't need the TVV anymore. If I've got one, I'll send you the one from my 77. Sorry to have steered you wrong on the 78 version.

And there was some beer involved. And grease. Lots of grease. The aftermath: You, my friend, definitely earned your keep yesterday!

Bringing a 1977 Z back life
That's awesome! And I would recommend putting some brake lines on the master cylinder before you put some miles on it. So... Was that really the first start? Or did you start it a couple minutes before just so you wouldn't look like a doofus cranking and cranking and cranking?

Dashboard wiring
No worries. So what year are you working on here? And my guess for that two position connector continues to be illumination bulbs. And based on the location in the car (which can now be seen in the wider angle shot ), I'm suggesting the bulb that lights up the gear shift position. Maybe that connector is supposed to tuck lower and go to the gear shift?

Dashboard wiring
I'm confused. I'm not sure what connector you are even interested in... In the first pic (of the wiring documentation) you centered the camera on a three position connector labeled LW/R/LR. But then in the second pic you are showing a two position connector with G/W and R/B. So which connector are you asking about? And close-up pics are great, but "context" could be more easily obtained if you were to pull the camera back a little. https://en.wikipedia.org/wiki/Blind_men_and_an_elephant

Combo switch
Green/white and red/blue is usually instrumentation lighting. Dash lights, HVAC illumination, ash try light... That sort of thing. I can't tell from that close-up where that connector is, but I suspect it's for a bulb somewhere.

1975 280z getting crushed for scrap metal
Yes, the metal mounts. I can get the plastic part if it's cracked. But I don't have the metal "L"s to put the plastic on.

Sweet. And if you want to swing by PHL and pick me up, I'd be happy to give you a hand. I got just one good arm right now, but I'll do what I can!

1975 280z getting crushed for scrap metal
Got something else... If any of them still have the engine, I need the spark plug wire loom brackets. The divider thingies that bolt to the valve cover.

Yeah, same thing at the P-n-P yards near me. When I go, I look like I'm going on safari. Everyone else looks like they're out for the weekend for good behavior.

Wiring EU Taillights/TS Problem
I have no idea what the differences are between the harnesses, but is there the possibility you could remove and reposition the contacts from the connector shell(s) to convert what you have into what you need?
