260 tach woes 1 2
by racer88- 16 replies

Hi everyone I have a 74 260 and the PO for reasons unknown has removed the resistor in the blue wire that supplies the signal to the tach from the coil. I have searched with no luck for the value of that resistor. Does anyone know what that value might be. I would like to hook up the tach but do not want to fry it, and the chances of finding an original replacement here in southwestern ontario are very slim. Any help would be great. Thanks in advance Bob Morris

I replaced the 40 year old, non working door switches today. the passenger side works fine but the drivers side is puzzling. At first it didn't work until it was inserted back into the opening. Shortly after the door open buzzer started, never knew there was one. Went back to check after sundown and now the drivers side switch and door buzzer don't work. The passenger side has no issue. Any ideas?

I would like to work on rebuilding my wiring harness over the winter months as a good indoor project. The problem is, I don't know what size of wire to get? Does anyone know what gauge wire is used for the 240z? Also, any good places to order a spool of wire. Thanks aplenty. carl

As before with the ZX alternator adapter, Dave Irwin and I have come up with a new wiring product for 240Zs. This one is a safety and visibility improvement. It is - as was the alternator plug before it - simple, affordable, and 100% reversible. The addition of a pair of these adapters will convert a 240Z's front sidemarkers into dual function lights. Once installed, the markers will flash in sync with the signals if the parking lights are off, and opposite if the parking lights are on. The way they work is shown in the movie linked here: http://video.classiczcars.com/user_video_detail.php?mId=2315 The theory is not complex, and wouldn't be tough to do with wire taps and …

Prior to today, my tail lights were working. I have Dave's front turn signal harness. Love it to Death, as Alice Cooper would say. I went to install Dave's Parking light/instrument light upgrade. I followed the directions. As soon as I installed it I blew the 15a inline fuse. Also the tail light fuse. Then no tail lights. I took it out of the circuit. Still blowing tl fuse. So I pull out the multi meter. Got a circuit from the fusebox screw to the left fuse holder on the TL fuse. Then I pulled the large connector apart under the steering wheel (this is the one that Daves mod plugs into). I have continuity from the same aforementioned screw to the green/wh…

I am fooling with the wipers on my 77 this morning. Symptoms are: When turned on and right back off, it makes two swipes. Usually. When turned to slowest delay, it initially works just fine-perhaps 5 cycles; after that it often goes to a slow drag across the glass with no delay between cycles, just really slow. Doesn't always do this. Sometimes slow to park After being in on position for a while and then moved to delay, it doesn't wipe without resetting the switch. Everything works fine in on position and both speeds work fine. It is more annoying than anything. Is it likely the motor, the switch, the signal intensifier? Any thoughts? Thanks, Leonard

My son and I are working on a 1977 280Z and are stumped with some electrical issues (surprise!) The primary issue I need help with right now is know where to hook one of the 2 red wires that come out of the wiring harness near the battery. One of the wires has a male connector, which hooks to the positive battery terminal via a fusible link. The other red wire has a female connector but does not connect to anything... I read somewhere that this probably connects to the negative battery terminal, however there are no wires coming from that area. ??? This is a new project car and it's possible a wire is missing or fell off in transit. Any help is greatly appreciated. …

I'm hoping someone can help, my left turn signal and park light come on at the same time. The turn signal does not blink, just stays on. If the park light is on both bulbs also glow. If the turn signal and park light are turned on at the same time, both bulbs go out. there is obviously a short somewhere.....I have had all the switches apart and cleaned them, this has not made a difference and have checked all the connections and all seem fine. please help.

Ok, I've seen a lot of threads on Z electrical issues and mine is probably just another variation on the theme...flashers stop working when brake pedal pressed; headlights also throw in some other variations when combined with brakes. If you have any suggestions I would really appreciate it. I am still cleaning contacts, checking bulbs, etc just to cover the quick and easy stuff. Also, I have one of those color coded wire diagrams I purchased off e-bay and its pretty helpful, but it references a hazard switch that seems to be a common junction for hazards, turn signals and brake lights. Does anyone know where this switch is located? I don't think it is referring to th…

Great info on the color wiring diagrams. Any chance someone has a link to a colored one for an 83zx turbo model. I am nearly complete with the conversion but have very different and very conflicting wiring information and no longer sure what to trust. Thanks! Leonard
