Ah, do you mean if I move the coil, continuity should appear if it is the proper distance from the center shaft?

Definitely agree but I just don't get how my pickup coil can be dead from that (isn't that block just a huge magnet)? I checked all of the wiring and there aren't any visible breaks, even under the cap.

Update: I removed the distributor cap and the front of the pickup coil seems to be scratched, (almost like its been rubbing on the rotating portion of the distributor) there are also very small metal shavings magnetized to the back of the pickup coil. I tried to shake the main shaft around and it can be moved somewhat but is still very much connected to the engine (not sure if any of this information helps). Video I just filmed: https://youtu.be/N8R1Ps-r3Pk Would the pickup coil's outer casing being rubbed against ruin the internals? Also, if that is indeed what happened, it would probably be a good idea to purchase a new distributor, correct? -chase

Hi guys, While taking the car out today, everything was running great until I went to wide-open throttle. After about 20 feet, the car flat out died and refused to start. The car was low on gas, so after pushing it to a gas station and refilling it, it started right up 3x in a row and was able to drive it home. I just went down to try and start it and it is now dead. I pulled the coil wire off of the distributor cap and grounded it against the body - and it seems I am not getting any spark now. I used a multimeter to poke the 2 coil poles and got less than 1.8ohms so according to the FSM it means the coil isn't bad. Any ideas as to where I should start to look? It seems like this is the result of an electrical part that was on its last legs or something... EDIT: I just checked for continuity at the end of the two pick-up coil wires (in the black box where they are bolted to the harness) and did not get continuity. Could that be the issue? Box on the right is what I'm referring to: https://www.classiczcars.com/uploads/monthly_2017_02/Screenshot_2017-02-21-14-44-04.png.07517510cbd3dcbe526420d18fa8092e.png -chase

My rheostat works but I've always wanted to bypass it to see if the lights get any brighter because who knows how much/if its corroded on the inside.

I have a 280z. If that's the case, then maybe somebody put a 240 tach in it? Either way, on mine, the indicator lights only had one BW wire each and once I cleaned the mounting bracket and bolted the housing down, they worked.

On my tach On my tach, the turn signal wires are single wires (BW). The gauge illumination lights have 2 wires (GB/GR)

Update for you: I was wrong about a burned out tach light - the bulbs are just too dim to illuminate the area where the redline+ bit is. The turn signal lights still aren't working however. I ended up using a test light to verify that I am indeed getting a light pulse to the harness connector for the signals and I am. I did some research online and found out that the indicator lights (unlike the illumination lights) are indeed 1 wire and not 2. So I'm guessing that means they aren't grounding properly to the housing (or the housing's ground is missing, right)? Update: Got the lights working. For those who have the same issue, the tach grounds to the body via the tach mount screw on the underside of the dash. Sand it down a bit and crank that screw and that should fix your grounding issue.

Hi guys, Odd question for you. One of my tach illumination lights died (the other 4 still work). A week later, the left indicator dash tach light died, and today the right one died (the front & rear exterior indicator lights all work however). I tried to remove the tach but 90 minutes later I couldn't get it out (on account of the dash cap's lip that surrounds the gauge. I also was able to unplug the 2 general light connectors behind the dash after a bunch of fiddling hoping to see some corrosion, but they look brand new. I also took a look at the bulbs, and they aren't burned out. Anyone have any other ideas? -chase

Yeah, those are what are on my car. It makes sense that the sub harness and sensor connectors have matching colors. That said - if the bullet connectors are flip-flopped in the main harness, suddenly that little trick's helpfulness goes out the window haha. @SteveJ Yeah, that's what I ended up doing - checking the main harness wire colors then just following the wire to the plug rather than looking at the sub-harness wire colors

I was going through the FSM and couldn't find that. What page was that on? (Thanks everyone btw)

Quick question for you. I can't seem to find a wiring diagram that includes the coolant temp sensor & thermotime switch wiring colors in the FSM. The thermotime & coolant temp sensor (temp sensor for the ECU, not the temp gauge) each have a bullet-style to standard EFI connector harness (one harness has green wires and the other has black). Do you guys happen to know which harness connects to the coolant temp sensor and which goes to the thermotime? -chase

How did you remove the rest of the plastic handle grip? It seems to be glued on there.

Was this tough to install? I'm going to try JB weld first (https://www.oreillyauto.com/detail/b/j-b-weld-4009/chemicals---fluids-16461/glues--adhesives---sealants-19861/specialty-adhesives-17689/568b785d32e5/j-b-weld-20-gram-superweld/33120/6029295/) but if JB doesn't work, I'd like to try that.

Awesome, thanks

Do they sell that grip anywhere? I can't seem to find it.

Hi guys, My handbrake handle broke today. I've tried glueing it back on with superglue but to no avail. Anyone have any recommendations on what I can use to get these back together properly? -chase

Good to go. I checked continuity from the AFM housing to the plate welded to the car that the screw screws into. Is that good enough or do I need to check continuity between the plate and something else?

For me it is on regardless of fuel level

I don't believe so because here in TX it's been hot since before I installed it but an interesting theory anyhow.

I really wouldn't drive on that - its 40 year old rubber...

For what it's worth I got the same part from ZCD and had the same issue. They sent me out a replacement which I will swap in eventually. I also remember that this problem didn't start immediately - it manifested after a few months...

Ah ya, I definitely don't have that since it's not bolted to the bracket at all...

I don't see one attached to the bottom of my AFM. Is that why it runs fine? It sounds like a good idea to have one of those so should I try and add one of these?

I noticed that a lot of pictures show the AFM having a ground strap that goes to the bracket - mine doesnt have one and doesn't even touch the bracket...
