    '75 280z
  1. 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.
  2. 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/
  3. 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.
  4. 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.
  5. '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.
  6. '75 280z can't get spark

    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.
  8. Fuse link wire identification

    this schematic might help you identify the line.
  9. '75 280z can't get spark

    Thanks Chas, Zed Head. I put spark plug onto the valve cover to test it again. The result was same Coil test: Positive Post Connect Voltmeter Positive to Coil Positive and Voltmeter Negative to Battery Negative post. Default shows 0v. When turn IGN, it show 12V. Coil test: Negative Post Connect Voltmeter Negative to Coil Negative and Voltmeter Positive to Battery Positive post. Default shows 12v. When turn IGN, it dropped to 0.31v.
  10. '75 280z can't get spark

    Here is spark test.
  11. '75 280z can't get spark

    I installed new rotor and new cap too. Spinning rotor check
  12. '75 280z can't get spark

    Thanks Zed Head, Chas for your input. My 280z is none CA model. Actually, after this problem, I thought ignition module or dizzy itself failure. So, i decided to swap to 280zx distributor. I follows blues instruction. http://atlanticz.ca/zclub/techtips/distributor/index.html I need to modify one line. BL line needs to added to positive post on Coil. Otherwise, nothing happen when I turn key onto IGN position. Now I can get rid of those... Even though after swapping Dizzy, and get rid of ignition module, the symptom hasn't been changed.
  13. '75 280z can't get spark

    I know there are a lot of "Can't get spark" topic before here and there. I read through those topics but still can' figure out what was wrong with my case. It was running strong before I shut off engine. Next day, I cannot start engine. Trouble shooting what I have done follow 280zfuelinjectionbook.pdf Fuel pump Remove Starter motor IGN line. Turn key on to the IGN position to hear fuel pump sound. It works. Spark check Remove Spark Plug and leave it on the top of valve cover with cable connect Trun key onto the IGN position. No spark! IGN signal blue line check Under the dashboard, Check blue line is connected. Coil Check Use voltmeter set to 20 Connect Voltmeter Positive to Coil Positive and Voltmeter Negative to Battery Negative post. Result show 12V. Passed Connect Voltmeter Positive to Battery Positive post and Voltmeter Negative to Coil Negative. Result show 12V. Passed. Connect Voltmeter Positive to Coil Positive and Voltmeter Negative to Coil Negative. Turn key onto IGN position. Result 0V. FAILED What should I test next?
  14. Thanks for posting photos. Looks like everyone mount relays, fusebox in engine bay. In my case, I need to mount power window relay, power lock relays, fusebox for constant, fuse box for +IGN under dash. I'm struggle to find place to mount... Recently, Power antenna finished. https://youtu.be/ytbBwa7H1T8 Viper Power Lock installed. https://youtu.be/DbhKbMWYmIY
