280zx 1979 2+2 slick roof restauration

Recommended Posts

Yesterday I went to Mart to look @ the 280ZX. He let me drive it a bit, thanks Mart ?

He has some things left to do, but overall it drives really nice ! Restoration looks really nice.

I think there are always things to improve on any (hobby) car but i have a small "still to do" list of things.. One is the rear carpet and upholstery stuff..

As my upholstery guy is a busy man and i'm not afraid of trying to do it myself i got to it.

 

this is terrible.. the old part...

cleaning!

Much better.. new upholstery by... me!

Cleaned the box.

Next part.. cleaning was enough.

Good to go!

Rear part..  not bad for a first time ..

The end result. (I installed the original (!) 41 years old carpet here!!)

The radio and cassette deserve some extra attention/explaining in a 280zx..    these are the ones that where put in the Euro version (1979 in this case)  a radio from clarion in mono, speaker in the dash ( mid.top )

For the cassette player in this case a Clarion unit.  But can also be a Hitachi?  I think i have seen both..   The cassette is in stereo.. The speakers are in the back near the rear seats ..

So funny, you can play the radio and cass. simultaniously!

 

Working on some rims of 45 years old now..  tested 8 of them on a balancer and they were good to go.. to the sandblasters.. (me again... haha)  (The 9th rim was a bad one and just in the pic (lower one) for to show the difference!)  Lower one has some damage.. maybe i could weld some alu in but i got 8! good rims.. so don't think i'll do that in the near future..

Years ago i bought a analzer for a datsun..  in a very nice condition, don't know how it works, think i need another extender so i can check a 280zx EFI system.. i got 2 extenders type: j25400-12   and i have done some investigating and need another one.. the number of that on is escaped me...

A real electronic guy always want to take a look inside hey....  @Captain Obvious

Here the extender... wrong one.. (for a datsun 280zx.)

20200913_164221.jpg

 

No idea were these go..

Since the first of July drove about 500 km's with the 280zx  and i must say it drives very well, there are always things to improve and one is the idle speed of it. When cold it's 1000-1200 rpm and go's to 600-750 rpm  depending on how hot the weather is and how warm the engine is.. but there is to much difference so i think i'm going to put in some new sensors and maybe even check (the computer)  for old capacitors and such..  It never stalled on me but it was sometimes close with just 500-550 rpm's.  (It could ofcourse also just be a bad connection on one of the sensors..  It's parts under the hood are all 41 years old and i take my had off for it doing so well!

Very nice! Thanks for the pics. That tester is very cool. Hope you can actually get it to work!

Looking at the back of the board, I don't see anything that looks like a microprocessor. I I would have expected it to be computer based, but unless they used something small (unlikely during that time), it doesn't appear so.

That thing must've cost thousands when it was new.

I saw a datecode on a powertransistor. week 05 '79..  so the machine is of 1980 or so, the microprocessor was still in development..  i think?

Hihi, yeah.. i had it with the manual, and it was laying IN between the case halves.. i thought.. it will get wrinkled this way and i left it out and thought to read it some time..  now i can't find the EFFING thing?  oh well.. it's somewhere in this house.. ;-)

I think so... i have a brand new NISSAN CONSULT, bought from a Belgian nissan (sub?)dealer!!  To check my 300zxtt i thought..  but it won't  work.  It's a complete case with all the special cables, leads everything!  Not a scratch on it... but the only thing it does is "peep peep peeeeep..  when you touch the screen..  THAT was something special in 1990 !!! A TOUCHSCREEN!!!!

I ones opened it with a friend who (maybe?) has worked on the development of your smartphones processor!  ;-)  (Samsung)   We could not get it to work after a new back up battery and some power from a transformer. :-(  

I need the servicemanual for the servicemanual-tool  haha..  you any idea where i could find the circuitdiagram of a nissan-consult 1 ?

Sorry, but I have no idea. And that later device, I assume, IS computer controlled. Way more complicated.

Hope you can get that tester operational.     :geek:

If only i could find that damn user manual...!!  ( I don't know if i got the right overlay but do know that i have the wrong extender.  I got j25400-12 and i need something like j25400-32 or so.. i red that long ago)

oh.. i have the extender twice (same j25400-12) so i could  exchange one..   On the other hand.. i asked myself.. why 2 the same types with this analyzer?  Is the older one (single one with a serial number!) defect and now theres a new(er) one with the analyzer?  Maybe it's an idea to open up a extender to look for damage..  yeah the older one with serialnumber 4009.

I took a quick five second look on the internets for info on the tested and turned up what appears to be a manual? Maybe?
http://datsunforum.com/efi-troubleshooting-kent-moore-j25400-analyzer/

datsun_fuel_injection-105.jpg

It's in .jpg form (not pdf), so reading through it is a little more difficult.

I'm assuming you have already trawled the web looking for info on the tester and with that in mind, I'm assuming you've already been through this doc? I could get lost for hours looking for info...

I know it's on the net, thanks but i meant  find it here in my house.. i always prefer the original manual over a copy on the net.

It would be very nice to test a 280zx system, but..

I need the  adapter J25400-36..    and i don't think i'm going to find that one... Maybe i can change one of my J25400-12 adapters in a J25400-36.  anyway i got other things to do.. recovering from a hernia i had over a month ago..  happy i can walk again haha..

Make a copy of the net anyway, thanks again CO!

I found some pic's on the net that are the  supposed parts one would need if he wants to check a 1979 280zx EFI system..

 

This is a J25400-32   I read i need a J24500-36 adapter to check a 280zx s130 1979 model..

analyzer J24500-36.jpg

 

On the sticker it says J25400-30 ? huh...

analyzer.jpg

 

On my analyzer is a blue overlay. I need the red overlay with DATSUN on it.. But i could use some tape over the blue overlay and copy what's on the red one haha. (i bet there is not much difference.)
