i'll preface this with the fact that i rebuild my engine and refreshed the engine bay which involved removing everything from it. i didn't touch anything under the dash. it's definitely not the starter; the engine turns over when the starter solenoid is connected directly to the battery. when the key is turned, the dash and body lights come on, but when the key is fully engaged, the seat belt alarm comes on and there's a clunking sound coming from the area above the fuse box. i've got continuity between the yellow wire on the starter solenoid and the black/yellow wire going to the ignition switch, but when i've got 12V going to the switch, it never gets to the yellow wir…

I've had my 75 Z for 6 months now and the entire time I've not had turn signals ( like my 76 Z before ) and it KILLED ME. So this weekend I decided to tackle the issue. Here were my symptoms before: All hazards except front right blink, no turn signals at all. Every parking light is lit. I ended up taking apart the hazard switch and cleaning it, purchasing a newer generic flasher relay, and taking apart the turn signal switch and cleaning it. I followed a few helpful threads here and got some good advice toward the likely candidates that might be causing my problems. Afterward, my symptoms were these: All hazards except front right blink, all turn signals except fro…

since i've gotten my engine back in the car, i've got no electrical power at all. no lights, no reaction to turning the key, et cetera. the battery seems to be fully charged, and i was very careful to reattach everything just as it was before the rebuild. i've replaced the starter unit and the fusible links, but that's all i've changed. if there's one thing i'm absolute pants at, it's electrical stuff. where should i even start looking? is this being caused by a short, possibly?

Ok, So I'm trying to wire up a new turn signal system since the stock one's don't work. I know I need a thermal flasher but for some reason I can't seem to find any good schematics or directions for exactly what I need and what order to wire everything in order to make them work. I would like to put a switch in the center console and attach it to a small led that will illuminate to let me know that the turn signals are in. Anybody have any links or any ideas of the best way to do that? Thanks in advance for any tips you guys have, Fletch

Is there a proper way to wrap the wiring on aZ, so it will stay on, look nice and not unravel after a year? It seems that no matter how your wrap it, it still looks kinda crude, but the platic split loom stuff seems out of place on a classic car. I have just been re-wrapping the unravelled stuff, and applying a little E-6000 (or sho-Goo) to keep the ends attached. thxZ

Where can I buy a new positive battery cable for my '78 280Z? Went to start it yesterday and it tried to start and then just clicked. Battery was on a battery tender and showing fully charged. There was some corrosion on the positive post so cleaned that off and tried again. Nothing. Took the 7 year old battery to Walmart. It test fine. Took the battery back and reconnected it. Car starts. Tighten it all down. Won't start. Just click and nothing. My father in law sees some smoke at the positive cable end. Jiggles the wiring and it starts without even tightening the cable down. What should we do? We were thinking replace the positive lead. I looked at MSA and they sell som…

Well I am about tired of the crappy lights on my Z, and I am desperately wanting to update them. My cars alternator is completely stock as is all my wiring. I would like to upgrade, but was wondering what is the best choice, for a stock wired 240Z I know Zsonthebrain sells that fabulous wiring harness, and thats a good option. But is there an improvement possible without it?

I'm having a problem with my dash light circuit on my 1975 280Z. When ever any lights are turned on the 20amp fuse for the Lighting/dash lights burns out. All the running lights will work if I disconnect the dimmer resistor. Using the FSM ( Page BE22)I have done the following steps: Checked all lamps in circuit (Running lights as well as dash lights) for corrosion and have checked that all lamps are good by pulling out all gauges and testing them with an outside 12 volt source. Checked the dimmer control and registers good with 10 ohms at full resistance. Have checked the fuse block front and rear. All good. I have disconnected all the instruments from the instrument ha…

As you could guess the previouse owner of my 1973 240z had a push button starter which I wanted nothing to do with so I bought a turn key ignition and now my poor baby wont even sing a note for me... nothing not even a little grumble. I have limited knowledge when it comes to electrical but from what ive read if you have a problem with your ignition you either bypass the relay and install a pushbutton starter or buy a knew relay. So my question is I guess has anyone done the push button back to turn key conversion? I really need help so it would be much appreciated if anyone chips in on this one. Pictures of a factory relay and switches (steering collum electrical for a 2…

On a previous post, I mentioned that I had noticed that sometimes my AC fan and my radio would keep running, even after I turned the key off. That post was about a problem with the AC blower fan and radio that turned out to be a loose wire, and was not related to the AC and radio problem in the other post. Today I figured out that the random AC fan and radio running after the key was off is not so random. Both the fan and radio will continue working after the key is off until you take your foot off the brake. They do not come back on when you hit the brake again. Now...newer cars will allow the radio to run until you open the door, so maybe this thing I'm experienci…

Help! I need the lists collective wisdom. I drove my 260Z this morning to my kids hockey game. When I went to leave I turned the key and nothing. Dead silence. No hums, no fuel pump, no lights no radio... I cleaned the poitive terminal which looked clean except for a little corrosion on the outside of the clamp bolt. the ground looked fine and tight. Nothing chaned when I tried to start it. I tried to jump it and I had a hugh arc that melted a spot on the terminal. I came home and searched the treads and the closest I found was a "Dead Short" in a battery. So I pulled a battery from my 240z that was on a charger and installed it. Still nothing. Then the ran came and I …

Are the antennas interchangeable between a 240Z and a 260Z?
