http://www.painlesswiring.com/ At this point in the game with my 73 240Z alot has changed. With the change in plans (88 corvette tpi 350 w/brain) I have been looking at doing A full rewire with newer style fuse block from painless. As anyone who has or had A early Z can tell you there elec. systems can be A nightmare. I am just looking to get away from elec. problems later. At this point I have my Z 's interior all out other then the dash now and am thinking this would be the time for this. Now I have done A painless kit before but that was on my 74 corvette and with that car the name of the kit (painless) fit. It took time but no big deal. If anyone else has ta…

I need some help with my rear defogger: The switch works, and power flows through the lines in the glass, but the rear window stays foggy in the morning. I have an old voltmeter and determined that around 5 V flows through the lines both from the glass to the ground (drivers side) and from the hot-wire (red-black wire on passenger side) to the ground. My Haynes shows that there is a 20A fuse between the glass and defrost switch, but since everything gets power that fuse must be intact. Will the glass physically heat up to the touch if it is working properly? Maybe I don't have enough power flowing through… If that is the case then maybe the lines are corroded somew…

I've been told that the '73 Z had some stuff that was exclusive to that year. In the engine compartment; firewall; passenger side, there is a small electrical relay(?) box (about 2 1/2" X1" X 1 1/2" deep). It has a box plug that plugs into the wiring harness. Mine has fried and now the car won't start..guessing... relay to the fuel pump? Have looked high and low in junk yards (found a '72 & a '74 with no such thing) and at the Nissan Dealers (nothing showing on the fiche system). Help!

Does a coil from Nissan have a Nissan Part # printed on it? I want to get a stock coil to swap for my MSD coil so I don't get dinged points in a show. Courtesy Nissan has them for $50. I have been talking to this guy Doctor Z, who sells a lot of parts on Zcar.com. He said he has a used one that looks brand new for $25, but it does not say Nissan or have any recognizable part numbers. He said it says Hitachi on it and had the marking ECH IN IC-12 printed on it. It is painted black also. Anybody got a stock Nissan coil they could take a look at quickly? TIA, Marty

Does this exist! I want a full electronic style (as opposed to electrician style, which is more of a wiring diagram) circuit diagram for the Z. I don't care too much about color codes, just how the car is actually wired. Thanks guys. -David

OK it looks like I'm just talking to myself here, but for other's future reference: The resistance at the coil was within spec the last 2 times this problem has occured. When I tested the wire going from the negative coil terminal to the distributor however, there was a ton of resistance. Once the car cools down, it's gone. I'm attributing it to the PO's splicing of the wire, or to the wire occasionally moving and getting close to the exhaust manifold and/or coolant inlet thereby getting the wire really hot.

My ignition is cutting out, sometimes hot, sometimes cold. Sometime it'll run for 2 minutes, sometimes 45 minutes. After about 10 minutes, the car will start again. I thought I had it figured out last week when I noticed a semi-loose connection for the coil, the + wire. That wasn't all it was, but I've deduced that when it happens, the circuit fo rthe coil is open somehow. How do I know? Well, during that 10-minute or so wait, I can disconnect the positive lead to the coil and reconnect it and nothing will happen. When the car is ready to start, I'll see a little spark when I do the same thing. Chilton's says the way to check the coil is to check the primary and secondary…

Does anyone have any experience with switching out the sealed beams on a 240? I am also thinking of placing driving light behind the grill. Has anyone had any experience doing this? Thanks

HI all, been having a little problem lately, and as part of my troubleshooting process, I want to confirm what distrib my car has. I believe it's the original single-points distrib for my '73, but want to make sure before I do anything more.... (pics to follow)

k, on my 71 240Z, only one headlight works (left). the other doesn't. so i went to where the bad light connects to the plug that goes into the wiring harness and disconnected it, then removed the whole light from the bucket. i then went to the other headlight, and disconnected it. I plugged the other light in its place, and it didn't work. so i figured the light was bad. but i was bored last night, and connected a 9 volt battery to the connector on the light, and it lit up (although pretty dim). is this just the flasher filament working? also, i noticed the light had some broken glass in it, and there was a chip on the INSIDE of the lens. am i mistaken, or do i need a ne…

my 71 240Z has no tail/brake lights or turn signals. i know the lights themselves aren't to blame, cuz when i turn the hazard lights on, the turn signals and the brake lights work. the reverse lights work as well. could the problem be @ the combination switch? the turn signals don't work when I use that.

Once again, In my efforts to customize my 74 I am looking for the unobtainable...Does anyone have any idea where I can find European style headlights, taillights and turn signals....There is a company called"Crystal" that I've seen on ebay that even had blue parking lights built into the headlight assembly and I know that MSA used to carry sosme but i just don't know where to turn...Also, I keep hearing about Japanese style lights but I have no idea what they look like..Do they use xenon type bulbs..? Please help.. Thanks in advance
