Putting in a replacement L-28

[Captain Obvious]

1 - is your voltage regulator.

2 - is (what's left of) a condenser that is supposed to tie into a blue wire that goes to the voltage regulator (among other things). It's purpose is to filter out electrical noise.

3- is your air conditioner compressor relay. Closes when the system is calling for cool.

Thanks Bruce. I don’t see another wire (the blue one you’re referring too) going into the voltage regulator. There is only one bundle coming out of the VR and it seems intact? I forgot that Nissan went with the combined alternator/voltage regulator in 78’. Is that the preferred setup or is this fine. I only ask because I had my Hitachi alternator rebuilt at a shop in Memphis that does this kind of work. (Alternator, starters, etc). If I need to replace this alternator is it easiest to bypass this and go with the combined unit. Also I found a condenser at zcardept but they only have them for the 240z and 510z. Didn’t see any for the 280z in my quick search online.

According to the wiring diagram, the blue wire that connects to that condenser comes out of the main harness and I would expect it to come out somewhere close to where the voltage regulator branch comes out. It should be a single blue with a bullet connector on the end. I'll look at my car when I get a chance and see if I can find mine.

As for what you should do with an alternator choice... If your original alternator and external regulator work fine, then there's nothing wrong with just leaving them be.

But if either of those parts (alternator or regulator) give you troubles, then I'd recommend taking the opportunity to mod over to the newer internally regulated version.

Nevermind... I found your condenser wire. Give me a sec.

This should help:

Thanks again Bruce.
Eibach springs arrived and they’re the right ones for the 280z.

Starting putting them on and ran into a small problem with the bellows I bought from zcardepot. I can figure out which way they go. The ends of the bellows have places to put clamps. One side is wide the other thinner and the diameter is larger on the wide side. If I put the wide side towards the bottom of the strut the bellow clamp area is too large (diameter) to cinch down on the strut, it ends up folding on itself. The other way around you cannot fit it over/around the upper seat. It’s would need to stretch pretty far and I can seem to get it over. Anyone else face this problem?





This last pic it what I think is the proper orientation but again it requires me to stretch the top part of the bellows over the flange on the upper strut seat. See first pic. Does this seem right?

Had a run in with a heavy hammer a a few months ago driving in a stake with my son. Lost an index finger nail two years ago removing the PCV from under the intake of the Z after the wrench slipped.

My concern with Rivnuts is that drilling a hole in the sheetmetal exposes bare steel to the elements, and since Rivnuts don't form a gas-tight seal (AFIK), there's a chance you would get some rusting around that hole.

I love the idea of using Rivnuts.  I've always sealed any sheetmetal screws or similar by smooging silicone into the hole and onto the screw before threading it in.

So I am just wondering, have you ever seen rusting around the Rivnut?

You can put a smoog of sealant on both sides of the sheet metal before inserting the the rivnut, then crimp it down.

I’m confused, I have no idea what you guys are referring to.

My translation... I believe they are referring to jonathanrussell's comment at the top of this page about how do deal with the battery tray refurb:

"To me, the best way to restore the battery area is to drill out the spot welds and remove the tray. If you do this, buy a nice, properly sized spot weld drill bit and extender, and practice removing spot welds without drilling through the body. You will then need to weld up the holes in the battery frame...or buy a new one.  I use rivet nuts to re-attach the tray to the body."

Gotcha, I was wondering what that was about, makes sense now.
