Are the dashboard wiring harnesses in a '71 interchangeable with a '70? Any major issues? Thanks, Mike

I realized today that my A/C compressor in my 77 280z is on all the time. even though if the blower inside is off, I could still feel a little bit of air (very cold air). 1.) I know this is not normal for the compressor to turn on all the time. I checked all the connections, they seems to be fine. Is this bad for the compressor to be on all the time? it seems the clutch is not working or is there something i need to replace, like a relay? 2.) Also, the a/c is really cold in the morning compare to in the afternoon. Not that cold compare to other cars. Does this mean that I need to put an electric fan in the condenser? Need help on this one. Also, the heater does not wor…

I found what looks like to me like a small coil of wire that could be a choke of some kind connected in the fuse box in series with the dome light circuit in my 70 240Z. It has electrician's tape on it so I don't think the factory put it there. From the attached picture can anyone tell me of what this could be? This is really winging it here but the only thing I can think of that might be connected is an auto arming alarm I used to have on a previous 240 that sensed voltage changes like when the dome light comes on, maybe the coil enhances a voltage change from inductive kick when the door is open to ensure the alarm is triggered? Thanks for any ideas. I plan on remo…

I have 1978 280z all stock. When i bought the car the po's song cut the wires off the ign switch. I got one from a ZX and wired it all up (not sure if its right because i am still a noob to schematics) So everything is all wired up, As soon as i turn the key to the "on" position the fusible link blows. What can be the cause of this? I have tried looking at grounds and all but i cant seem to find it any input would be appreciated

Hey guys, I need a hand with the wiring on my 240Z. Recently I have been trying to get the wiring working properly. The whole system is very shaky and annoying due to the 36 year old wiring. I recently got the head lights half way working, but have begun blowing the fuse marked IGN which also happens to run some of the gauges and four way flashers, I believe. Anyways, I don't know where the wires coming off of the fuse block go exactly, and I need a hand figuring it out. I've already tried disconnecting my gauges (oil pressure, water temp, fuel) and emergency flashers. I think this fuse also runs the voltage regulator, but I have that jumpered off because I am using a Z…

So, where to start? I know theres a short somewhere in the car because if I let it sit for about a week, it needs to be jumped. The Windshield wipers, when connected, don't turn of. And I have just had to replace the voltage regulator and now the alternator and now a fairly brand new starter is down too. Not sure if one caused the other but any advice on whats causing the damage? Or is it just bad luck!? Ehh.... A little more detail I guess wouldn't hurt. I had an issue with the voltage meter maxing out randomly which lead me to replace the voltage regulator. That seemed to fix the problem. I then let it sit for maybe a month and it wouldn't start. Could hear the fuel pu…

Hello, on my '72 I found out that I've got a bad alternator, so i've picked up a rebuilt replacement, the only problem... the dealer installed york air compressor. The problem I have is how to remove the old one and get the replacement in place. From the back i've got the support brace from the bottom of the compressor to the motor mount and in the front its the radiatior, etc. Now about the A/C system... it's not currently hooked up, I'm missing the idler pulley, but the system appears fine, i'm giving it a 50/50 shot at working, no oil seeping from the compressor and all is still intact. The switch under the dash still engages the clutch... so I don't want to remove the…

I'm looking for any leads as to where one can purchase connectors that will mate to my early 240 harness. The blade type connectors are the ones I'm looking for. I bought some from http://www.eagleday.com/blco.html but sadly they do not mate with the ones on my harness. The dimensions of the body of the connector is wrong - to large by a small amount. I have also found these http://www.crc2onlinecatalog.com/Index_Main_Frame.htm by searching the forums. Does anyone know if these will mate up? Any other leads to a source would be welcome. Thanks, John

New sending unit in the tank and the gauge reads 1/2 when empty. Guess how I know? Gauge is original and this was the first it has had to register in 14 years. Mike

Occasionally on really hot days my 240z sometimes doesn't turn over. I hear the "Clicking" noise but no soleniod/starter action. It's ussually after I've run the car a while around town so it's hot and the heat is close to 90F outside. My electric fans work fine, all lights work, the radio works and I'm upgraded with the 60amp alternator hookup so my battery stays charged nicely. I've checked all my grounds and cables and could not find anything. I've seen other threads here with others that experience this problem. Question: Has anyone installed this Starter Relay Kit; was it easy and did it make your staring more reliable in the Heat of Summer? It's listed on …

hi all, are there 2 different fuel pump relays for the 78 280z. the parts store stocks one that is different than the one in my vehicle. the one that's in my car now is twice the size than what the parts store showed me. the reason i'm replacing the relay is it looks like the original, and also because i had the rear of the car on jack stands doing brake work and when i finished the job and let the car back down on level ground i could not start the engine. i traced it back to the relay took it apart and the contacts were not touching, don't know what i did but got it to work, i could hear the fuel pump operating, car started . took it for a test run ran good till …

Sorry if this has already been beaten to death. I have a '74 260Z (build 3/74) and I would very much like to install a more potent alternator. I understand that the swap for 240Z's won't work due to fuel pump and seat belt interlock issues. I plan to go with an aftermarket fuel pump which I will wire from scratch with its own relay and oil pressure cutoff. The seat belt interlock was defeated by the previous owner and it looks like it was done by securing the emergency start button in the engine compartment in the permanently down position. I will not have too much electrical load - the only increase would be halogen headlamps and a slightly more powerful radio (50 w …
