Working on a friends car (1973 240-Z) and trying to figure out why we can not get the heater fan to run with the OEM switch. The fan has not worked for about three years. A year ago he took the fan out and wired it direct to the battery to test it and it ran fine. That led him to assume the switch was the culprit. I had an extra switch, which we tried with no success. I'm wondering if there is anything between the fan and the switch that we may be missing. Of course both fan switches could be bad but the odds are at least one would be working. Is there an easy way to verify the switch is good? Any other thoughts regarding things to check.

My power antenna worked fine when I bought the car but when I set it up for the suspension refreshing I put the antenna down, now it will not go back up. The motor works, in either direction. I was going to just jump into it, but wanted to check with the experts first in case it is always the sample problem...

As a rookie Z owner/project starter...today I purchased a new battery, brought it home, put it in, and there is no power in the car when the key is turned. We are currently trying to troubleshoot it.....but any help would be much appreciated. I have no intentions of trying to start the car today, just wanted to see if there were any electrical "issues" and there may be.

I have 2 white wires with bullet connectors coming out the top of the fuel injection harness under the kick panel just inside the door jamb) that I can't identify and don't seem to have anything to plug them into. I also have a stray black wire coming in from the engine compartment (in with the main harness) on the passenger side with no apparent connection. Also...... I have a wire coming off the water temp switch (I think) that has a round eyelet to go under a bolt that I cant' figure out where it goes. I have searched the FSM and the fuel injection supplement and have yet to find the answers. Thanks for any help. I'm in the final stages of reassembly on this car a…

Hey everyone!....I tried the upgrade using the connections below and a 94 honda motor. It worked but the wipers were going down and parking in the full up postion. That is when I got stupid and switched two wires on the relay. I think it was 85 and 30. anyway now I have nothing. I have the FSM and two manuals but I can't find why I am not getting power at the motor connector or the wiper amp. I did some basic troubleshooting. First I checked the fuse and it is good. Then I disconnected the negative on battery and did some continuity checks on the combo switch as per FSM, that checked out. Next I checked the continuity on the motor connector. Black to frame grou…

I have a 73Z with the orginal radio. As you know it only has one speaker hooked up in the back. I was wondering if I can hook a 2nd speaker up to the radio. I want to add a 2nd speaker in the back on the other side. Will this work and how would I wire it? I don't want to add a different sound system just the 2nd speaker.

The intermediate wiring harness for the blower switch has a small connector that is not identified in the Supplemental FSM. The connector has provisions for 3 pins but has only two wires - red and blue. I'm referring to page 26 of the '71 Supplemental FSM. As I reconnect my electrical system, I'm trying to ensure there are no orphans. I did not mark this connector back when I tore it down, so it may have been unused at that time. Any ideas? Thanks, Jim

I just put a new dash in my 72 Z. After installation, all systems work with the exception of the temp side of the gauge (the oil pressure gauge works). Both systems work off of a common plug, so I know the plug was connected. Any ideas why the gauge doesn't work? We put working gauges in the dash from my car, so I know it worked before installation in the new dash. Any help would be appreciated. Thanks. Guy

Hey guys! I'm hoping you can help with a question I had regarding the ammeter in my 71. ====== The situation so far:I was driving my beloved Z last night. In fact I had been driving it pretty much all weekend without any issues. Stopped at a light the car just died. It was cold last night and I had the choke on, I noticed it was still partially engaged so I returned it to it's normal position. The RPMs dropped and the car died, I'm hoping a simple carb retune will help with that. When I tried to start it back up I got nothing, no response at all. I pushed the car to the side and then checked the wires for loose connections. I tried a second and third time. the last time I…

The antenna on this 71 240z does not seem to be stock. Here are the parts (in sequence) when removing/installing The area between the rear quarter panel (fibreglass) and the rear deck: There is a wingnut and stud which I guess is where the original antenna is attached. There is also a drain hole for a tube coming out of the antenna (potential fume hole). Lots of painted ziebart in the bottom too Here is the tube in place. I used the wing nut to ground the antenna's ground lead.

Now that I've got the car running I'm trying to fix the gages but a few of them dont seem to work. for the temp/oil gage the oil works but the temp doesnt, I believe becaus my water temperature sensor isn't working .. but im not 100% sure. for the volt/fuel gage i cant get a reading on either, but the light goes on when i turn the key "on". the clock also doesn't work. Thanks in advance
