Hi, Anyone, replace the OEM tach with a white faced after market unit? If so, who's did you use? Thanks

A friend on the west coast picked up a set of gauges out of a 2+2 280z, I believe a '78, and before sending them out to me, I was wondering if there is a quick way to test them (and thus make it worthwhile to ship). After searching the forum, I found that you can do a quick test on the oil pressure/voltage gauge by using a 9V battery (if the needles rise, they are most likely good), but I just wanted to ask before sending any potentially risky voltage through the other gauges. Thanks in advance for any help on this!

I have a feeling a connection or wire between relay and fuel pump is fried or corroded as there is no continuity/power to the wires, but the relay works. Is this a common problem? Where can I find wiring after it goes in the relay connectors

I am in need of a 1978 280z ignition relay. I have been searching for two weeks and can't come up with where to find one. They seem to be discontinued? If anyone has one for sale, or knows where to find said relay, please let me know.

I try and start it and it turns over but will not ignite. I have checked the coil no sign of damage and battery is new along with the fuel pump and fuel filter. The spark plugs are in good condition as well. The only thing I can think of is there are a few clipped wires near the distributor cap that the previous owner cut and I do not know where they go and not sure if it would make a difference. Any suggestions??

I don't think the original positive battery cable is available any more for a 1970 240, so I have been using a generic cable for many years. I do need to replace it, as the connector has cracked. Any suggestions on a cable and length? The one I have has a big cable going to the starter, with the fusible link coming off the bolt. Any advice would be appreciated. Thanks Bob

Hey amigos, So, I've been trying to go through the car (a '78 280z Black Pearl) bit by bit to work out the electrical bugs (got the horn and the hi-beams working) and now I'm moving on to the tach. Since I acquired the car last September, it hasn't worked and has stayed frozen at 700 rpm. I've scoured the forum and found mostly things to do with 240z tachs, compatibility problems with aftermarket coils (mine is stock) and one thread that suggested a frozen tach was not wiring-related, but a failure in the tach itself instead. I've checked the connections at the back of the tach and they all seem clean and intact. I've also cleaned the contacts for the wires that connect …

Hey there- Just inherited a '76 280z from my elderly (83) father. Of course the clock isn't working and hasn't for 15 years or so. But I also noticed the voltage gauge was almost pinned at the right of the gauge. I read the forums about bad voltage regulators, etc., so I went out and tested at the battery with a multimeter. The battery was reading 12+ with the car off. And a little more when running, and topped out at 13.7 or so when the car was held at a steady 2500 rpm. Okay, so relief there. Then I found a post about adjusting the gauge with a screwdriver from the back. This allowed me to move the needle from dead right, but the range of the adjustment wasn't near en…

I only just put electric ignition on my 260z today...(It was points) Basicly I used a 2.4l dizzy(off a 80's skyline) and a "procomp" ignition box- it converts the magnetic pulse from the dizzy to a signal that works the coil and a new epoxy type coil. It works great ie starts easier, revs quicker, nice steady idle.. BUT.. the tacho works ok at idle BUT at around 3500-4000 it goes nuts and jumps around -jump to 2000 and flicks around everywhere. It used to work with the points setup. I read some where that a 280z tacho would work BUT I'am in Australia and no 280zs here! any ideas??

Almost two years ago, I got my dream car. A classic Datsun Z!(77 280 EFI) After trial and error working on it trying to figure out why it would not run for longer then twenty minutes I finally just pulled the motor. Blown Piston rings, crappy injectors, and after some financial issues, I finally got to finish up my rebuild this past winter. Motor is in, trans is in. My car does not work.. at all. Everything worked before the pull, now something is toasted. I have no lights, no electrical power what so ever. New batt, new cables, new terminals, new EGI relay, new ignition control module, still no juice. While testing theories the other day with a wire jumper to test connec…
