  1. The last post was 6 1/2 years ago. Not clear who you're asking. The negative post of the coil is the one that is connected to the ECU.
  2. Why don't you just reset the preload and see what happens first? The FSM says it's the same for new or used bearings.
  3. I didn't watch the video. Sound rarely comes through well on the old internet from the phone recordings. If it's that bad I'd take up the shop's offer to open it up again. That's not normal. The whirring noise is. Seems like you're sampling other people's transmission noises so the picture is more clear to you now. Maybe go to the shop with somebody who has a good one so the shop knows what a good one sounds like. Good luck.
  4. I think that what we're saying here is that they all do it. Another used one will to. And the 240SX 5 speed (AKA 71C) is essentially the same design as the 71B. Not sure but it probably does it too.
  5. You can find quite a bit around the various Datsun forums about the noise from the transmission when in neutral with the clutch engaged. Might be that your 4th gear grind just made you hyper-aware. I had three different 5 speeds in my car at various times and they all had the noise that went awya when you pressed the clutch pedal. I have a memory of @JMortensen telling a story about a new rebuild having the noise. I found one.
  6. Get a list of all of the bearings that they replaced. The adapter plate bearings are tough to do, they might have skipped those. Any notes on how far down they took it would help too. Since you told them to only replace what they thought was worn they might not have gone very far. More details on what happened after you forced it in to 4th might help. Did you drive it afterward? How did it get to the shop? Did the problem go away?
  7. Can't remember but I think that it might actually be in Monroe's Rebuild book. But here is a writeup that a past member put together. The towers are bored for the cam after they are installed. When they are removed any mismatch on reassembly can cause cam binding. I've never done it myself I just remember reading about it. He doesn't mention the tapping, I must have seen that somewhere else. Basically, if rotation gets tight a couple of light taps on a tower or two can loosen it up. The goal is to get everything torqued and have a cam that rotates freely.
  8. Somebody probably used the torque values in Monroe's Rebuild book. Apparently there's a typo in the book, the value is too high. Make sure you do the tap-and-rotate alignment when reassembling. Nissan considers the cam towers as non-removable.
  9. Here's another wiring scheme but I think that it causes the brake warning light to stop working. Or stay on. Can't remember. http://www.zcarcreations.com/howto/voltreg.htm p.s. if it's quiet when you're working on it you can hear the relay click and see a spark at the terminal when you reconnect the battery. That tells you that you still have a problem.
  10. I had the same problem. My memory is vague but I think that I found that you could just disconnect the relay and the battery drain would stop. But then the brake light in the dash does not work, for the parking brake or the pressure differential switch. The brake light even acts as an "engine not running" light. It needs power only when the engine is running, to turn the light off. Anyway, I ended up cutting the power wire to the relay, I think it's the yellow one, and tapping in to the fuel pump power line, which is next to the passenger seat. That restored the system to where it only had power when the engine was running. That is the key. The relay needs power when the engine is running only. In the meantime I think that you can just unplug it.
  11. Get the one for your year of car. I have found that the zstore AFM's run rich though. That could be a problem in CA. The old EFI engines take some work to get running right. It probably won't be just a bolt on and go project. It's possible that you don't really need a new AFM unless you don't have one at all. Have you done the electrical tests on it? Good luck.
  12. You might be on the right track. The relay is under the passenger seat. What wiring scheme did you use to get rid of the external voltage regulator? There are at least two common ones.
  13. Is it an R180 or an R200?
  14. Most of us call it an air flow meter - AFM. https://www.thezstore.com/page/TZS/PROD/11-3040 https://zcarsource.com/fuel-systems/fuel-injection-components/air-flow-meter-mass-sensor/
  15. If you have a meter or test light you can also check for power at that terminal when the key is turned to Start. That's what the ignition switch does, sends power there.
