I'm ready to re-install my engine bay wiring harness. It's that last major item I need to do in the engine bay prior to engine installation. I got a new main harness grommet, but how do I get it onto the harness? The grommet is not that elastic and from both ends, there are fairly large plugs that have to go through it. I'm not sure how to proceed and don't want to damage anything trying to force things. Last time I split it and glued it back together, but I know that's not the "right" way... Will post some progress pics of the car in the next few days after the harness is installed. Thanks in advance for your help!

So I have been reading (and trying to help) some of our Zed-brethren with various electrical issues and while I was at a visit to Harbor Freight today I picked up a Cable Tracker circuit tester. This jewel works in two ways, one by std. Continuity Testing and second by sending a Trace Signal down a circuit that is picked up by the receiver. The Trace Signal is pretty cool because unlike continuity testing, it is 'active' and you can follow a circuit with the receiver until it drops indicating an open circuit. I believe that this would work well with a multimeter for clearing up some of the mystery wiring we have been encountering. Best part is that this tool is $19 (p…

The 1971 FairladyZ-L for a while would occasionally just make a single "click" relay-type sound somewhere under the dash when I turned the key to "Start" and the starter didn't do anything. I would turn the key off, and then try again sometimes with the same result. Usually it would work the second or third time and the starter would engage. We replaced the starter, the switch on the end of the ignition tumbler, and checked the battery. All those checked out okay. When it just made the click there wouldn't be any electricity at the starter solenoid b/y wire where it connected to the solenoid tab. I jumped from the battery to the solenoid and the starter worked. No…

I can't remember ever seeing anything about these. I don't know what their called. they are the bendable metal with rubber coverings that hold down the harnesses,wires. I cut mine out with a spot weld cutter and was going to redo the rubber. Can you buy or make the whole piece? thank you, TimsZ

1st off yes I have done a search and well, there is no definitive answer to what is the stock wire hook up. No Pertronix, no ZX convertion. Just plain stock wire hook up. Ok, I just did a front harness replacement on my 73. The harness is off a 72 becuse it does not have that stupid aux harness off the voltage reg plug that wires back to the fual pump relay. Anyway, I had a differant setup with my last harness. What I need to know is the stock setup, stock wires, stock wire colors. What I have seen is the long strand with the temp relay wire, yellow also has a black wire with a spade that should go to the distributor. Coil plus side gets a short black/white wire and neg g…

does anyone know of a shop? As the work on my 7/70 progresses I've come to need restoration services for this alternator. Early type Nissan part #: 23100-A4800 (LT140-53) up to 8/71 26th-Z shows pictures and mentions the restoration of his for #26 and #27 in this post (#19): http://www.classiczcars.com/forums/thread16641.html#post121846 No mention is made as to where the work was done, and the thread (from 2005) contains a mixture of posts regarding early Z parts (not Electrical specific). Also--does anyone have a condenser that matches the one pictured that they do not need? If so please give me a PM. I will try contacting 26th, but wanted to get this in front of…

Did any 240z ever come with a manual antenna? I had a guy send me an antenna that he said was from an early Z. The fender mounting hardware looks about right but this is a manual antenna that scopes down to about 16 inches high. Any idea what I've got here?

I was driving down the highway at app. 3200 rpm's and suddenly my Tach drops to 2500 rpm's. The engine speed remains the same speed. Is this a Tach or coil problem. Doesn't the Tach receive a pulse from the negative terminal on the coil. Both the coil and the Tach. are originial to the car. The drop on rpm's last about 15 seconds then jumps back up. At first I thought it was a loose wire at the coil, but I don't see a problem there. This problem doesn't happen all the time.

I removed the Dave Irwin LED taillights from 721, planning to install in the "new" Z. Brought along the LED flasher that worked in 721, too. Guess what? They no workie! The "new" Z is a 10/70 '71. Any thoughts or comments, 'cause I'm stumped?

Hey all I bought my 240z a little bit ago (last year oct) and loved it. But a few months ago i had the car randomly just die on me on the freeway. I cranked it a few times and it started and I drove it around for a couple more week with intermittent problems where it would just die. but now I cannot even start the car. I did a bit of research and and it seems like the e12-80 is malfunctioning but while taking apart my distributor i noticed there is a pertronix electronic ignition in there. So now I am not sure what i should do....should i buy a new distributor (looking at a chevy HEI) or should i just try a new e12-80 (where should i buy one of those?) Also is there anyt…

Never had this issue before, but started my car to adjust the carbs and noticed a few intermittent arcing sparks on my coil from the ground (negative) post to the center wire from the distributor through the plastic housing. Happened just a few times and then stopped. Weird! Have not done anything new to my electrical recently. Have Blaster coil, e12-80 electronic ignition, and recently new, thicker spark plug wires. Car stumbled slightly when the arcing occured. Any thoughts?
