Recap: My starter is new, maybe only 2 or 3 weeks old. It's a 78' gear reduction starter in a '76 Z (covered all of this on the board). So, I'm driving to pick up some to-go food and head to my inlaws house. Car is running fine as I cross town, everything is good. I get there, eat, and upon leaving I find myself stranded. I put the key in and turn to start, dead silence. All i can hear is the fuel pump engaging. I checked the: 1. Battery (full charge) 2. Wiring to Starter - All Secure 3. Fuses (n/a) Basically we push started the car and got it home. Upon getting it home, it started once; but then the 2nd attempt it failed again. When you turn the key, its just quiet. No …

I need help identifying this box, as you can see the cover is all but gone and it sits nexto the fusible links directly under the poorly engineered hood vent on the passengers side that does not have a plate to stop water from pouring on to it. Not sure if i have to replace the whole box or if i can get a new cover :disappoin

I posted a Want ad for a friend of mine who is currently working on his car. My friend's car is a 73, but he insists that his tach is a 3-wire. Which seems to run contrary to what one would think. All of the wiring schematics I have show a 4-wire. I can't find anything that would help settle the question and I haven't had a chance to look at my friends harness or tach. One of the comments on the ad reads: Which upholds my (and other people's) thinking. So, the general question to the rest of you is which tach is correct? Hopefully we can get a consensus so my friend knows what to get. He's looking for a replacement because his original tach was always intermittent,…

On the schematic that zcar70 supplied it shows a speed adjustment. It that the recessed black slotted item just to the left of high center on the back of the tach? I have two tachs. One is over 200 rpms off and the other, just supposedly completely rebuilt, is 600 rpms off. Will that speed adjustment adjust the rpm reading on the tach?

After some tinkering, I got my 76 280 running, she's looking good. However, I have almost no functioning interior electronics. Here is what DOES work (interior/exterior): Exterior ALL exterior lights Interior Fuel gauge Voltmeter (whatever its called) Im not getting any functionality from any other of the interior devices, no horn either (just a clicking sound from the pass side firewall). Im sorry if this is to vague, Im Im new to Z's, but I do know that this forum is amazing for helping with these wonderful machines! Any responses are appreciated. Thanks again, John

My water temp gauge doesn't work. Bought a new sensor and was wondering how to swap it out. Work it out with vise grips?

Yes I know there are about a dozen write ups or questions about upgrading the early Z's alternator, but this one is a little different. The upgrade that I did was a 95 Nissan Quest alternator, which is rated at 110amp output. High for most Z guys but helpful none the less. I'm not done with the install yet but I will be soon and will give a full write up with pictures to help others with the install. So everyone knows now there will be modifications required for this, i have also tried to address the issue of the belts breaking with the higher output alt. as well. Let me know what you think of this as I go along any and all feed back is appreciated. Kevin

Im having trouble getting my 76 280z started. I did some thorough searching through these forums, found everything related to my symptoms/problems, and tried them all; heres what i did: Checked the fuseable links and cleaned all the contacts Cleaned the contacts to the starter, checked all the wires, ground, etc Made sure the ground from the battery cable was connected Scoped out the ignition, no fried wires, nothing. I can only get her started when i jump it, but when I get it started, it sounds totally fine. Its not the battery, I put a new one in a few months ago (and haven't been driving it). Tested the battery with a 50v meter, its fully charged. Also tested the alt…

I figured putting 12V battery (+ & -) to the blue and black leads should power the clock, but it doesn't move or make any noise. The guy I bought it from says it worked and says I need to connect it to the harness to work correctly. I plan on putting it in my 240, so I will be altering the wire harness anyway. I am just trying to determine if I have a working clock first. Any help is appreciated. Ken

I have a 73 that I have been working on. The PO had a small column mounted tach which I disconnected. He had the light wired to the driver's side parking light. Removed. I updated to a Pertornix module and in the process found a green wire and a black/yellow stripe wire cut off inside the harness that carries the wires to the temp sensor and distributor. Anyone know what they are for? My step father drove the car from Memphis to Phoenix with no problems. I still need to tackle the non-working stock tach. He also had an aluminum radiator with an electric fan haywired in. I removed all that and installed a 3 core radiator. I have a picture posted of the wires in question in…

Just got my 72 240Z. All the other lights work fine, but for some reason i cant get any headlights. I measured the current from fuse box and from the headlight connector in front. No current at all. Someone suggested that soak the fuse box in vinegar, i'll do that ASAP. But there is also another problem that might be related to this. The switch in steering wheel. It's acting strange, when i put the lights on, most of the time it works but not all the time. When i roll it on/off few times it starts to work again. All the wires are good and connected. :stupid: Also the ignition switch has some issues. Sometimes when i start the engine it tries to start and CLUNK after tha…
