  1. '75 280z can't get spark

  2. '75 280z can't get spark

    Thanks Jeff, Chas! I was so dumb. I waste whole 2 months to try to figure out this... Now I'm so happy all my wiring is done except alternator charge lamp. '75 280z had an ammeter instead of a voltmeter. I swap '78 Voltmeter. Also I swap with CS-140 alternator. I need to double check wiring for charging lamp.
  3. '75 280z can't get spark

    I re-checked wire again last night.... then I found out that I connected the positive wire and the negative wire opposite way to the IC matchbox. After re-connect, turn the key..., worked!!! Thanks Chas, Zed Head for constant advice! I can move to next area now! Sent from my iPhone using Classic Zcar Club mobile

    Hi JSM, yes. I’m getting positive voltage to the coil. It seems like some thing wrong to between coil to dizzy or IC. I’m trying to narrow down to find the issue... Sent from my iPhone using Classic Zcar Club mobile
  5. '75 280z can't get spark

    I replaced spark plug wire to new one. Still can't get spark. I check 1980 280ZX FSM. P25. It says, I need to connect Voltmeter to Receptacle. Do I need to connect to cable like this? or Dizzy's IC socket? When I connect cable, I got 12.Xv. But when I connect to socket on IC, I got nothing. 0.01v. Which way is the right way to test????
  6. I did same way what grannykont express using grease to remove piston. https://motofaction.org/mechanical-101/a-how-remove-stuck-seized-brake-pistons-with-grease-gun-rust/
  7. Hatch harness questions

  8. I installed power lock, power windows, Viper security system. Also I installed new modern stereo with 600W amp. Those need 4 relays and multiple fuses for IGN and +12V constant.
  9. Modern Car Stereo Receivers

    My '75 280z had only 1 speaker on driver's side rear. I got Alpine 6x9 speaker. It's really good sound! https://www.walmart.com/ip/Alpine-6x9-Coaxial-3-Way-260W-Wide-Range-Car-Audio-Speakers-SPS-619-Pair/48455393?wmlspartner=wlpa&selectedSellerId=1235&adid=22222222227035941564&wl0=&wl1=g&wl2=c&wl3=76741515514&wl4=pla-177944793154&wl5=9032178&wl6=&wl7=&wl8=&wl9=pla&wl10=112354589&wl11=online&wl12=48455393&wl13=&veh=sem You can purchase rear speaker panel from Z store. http://www.thezstore.com/page/TZS/CTGY/classic08j02 But I'm making my own one. For receiver, I got Alpine Bluetooth and USB only since I don't use CD anymore. https://alpine-usa.com/product/view/cde-143bt/
  10. That's nice big box. It's a bit too big. Since relay and fuse are within cabinet( those are for power lock, power window, audio, security), it does not make sense to extend cable to rout out to engine bay in my case.
  11. After removing transistor under passenger kick board, I found there are huge space available to mount. I created mounting bracket. Chopping metal flat bar and drill holes and weld them together. primed and painted with some leftover canned spray. Completed.
  12. '75 280z can't get spark

    I test the coil again. I disconnected all wires from terminal. Set Multimeter to 200 ohm. Connect Primary(+) to Primary(-). Result is 2.1 to 2.3 ohms. I found MSD Blaster SS. I tried it... Same result, still no spark.... What should I do next? Then, Test Primary (+) or (-) to Secondary (center) Set Multimeter to 20k ohm. It shows both 10.43k ohms.

    Thanks Chas, Zed Head. I put spark plug onto the valve cover. From Coil Negative Post, remove all cable. Add just one green wire. While turning key to IGN, tap the green wire other end to ground. I see spark on the cable to ground. However, I don't see spark from Spark Plug. I found one video on Youtube for MSD Blaster coil test. The author said: primary terminal test + post with - post Set to 200 ohm scale Expected : 0.5 to 0.7 ohm Secondary test + post and main lead Set to 2000 ohm scale expected: 4,500 - 5,500 ohm When I test with my Harbor Freight Tool's Free multi tester, the resistance shows vary for 200ohm for primary terminal test. For Secondary test shows nothing. It shows "1" and did not change any value.

    Looks like it's coil failure. This MSD Blaster 2 is not so old... ;-(. I will order new one.
  15. Fuse link wire identification

    this schematic might help you identify the line.
