Which wire goes where :stupid: , I disconnected the old coil and forgot to label them it is a 1978 280z. Does the black white wire go to the + terminal or does it go to the - terminal. Thanks in advance

Hello...sadly I have cooked my Z car today. And after owning it for over thirty years I accidenitally connected the battery cables backward. Can't imagine what I was thinking. Was reconnecting after installing relay wiring harness for lights and new fuse box. Since the ignition switch was off I don't think it got into the car. However, the alternator was smoking , and maybe new distributor (electronic from 280zx) and starter. None of the fuses in the new fuse box burned nor did the inline fuse for the lights. Should I start by stripping back all the wires in the enging compartment or what??? :mad: :sick:

I am trying to get my '73 240z ready for mechanical safety inspection in Canada, and I have run into some problems with the headlights. When I flick the high-low beam switch, one light comes on and the other goes off...and when I flick it back, the other comes on and the other goes off. I have replaced the sealed beams...problem remains. Please, any suggestions?????

Hey all, I am trying to figure out which relays are for my electric fuel pump. I checked both the FSM and the Haynes manual, but neither has a "map" of the relay block. Can anyone tell me which of the 6 or so relays are for the fuel pump? Thanks, Ayan

I am in the process of finishing the redo of my '73 240 . I have had to replace the entire wireing in the car do to a PO that had sh$% for brains. I am using the entire loom from a '72 . I am at the point now of connecting the ignition , wypers and light switch at the steering column which is all from the old '73 , and it has intermitten wypers and such. The connecters are different between the two years of Z and I am trying to puzzle through this. The wireing diagram for the '73 shows a relay for the wypers . If anyone has a '73 and can tell me what it looks like and or describe it , part numbers or letters , location or what ever , this will be a great help . I strip…

My 240z has had a problem starting after the installation of an MSD. The starter cranks very slowly. I went ahead and replaced the VR with a transistor type since it was the original and the problem is fixed. The problem now is that the ammeter jumps between half way and 45amps. It only does this when driving, not at idle. The lights and all are way brighter now, but I fear that maybe I'm killing my battery. The battery, however, doesn't even get hot. Does anyone have a clue what's going on here? Is the new VR bad? I'm thinking of putting it in my friend's 240 tonight to see if it does the same thing. thanks for any help, Brian s.

I've got an '80 alternator in my '73 240 and for the last year it has worked great. But last night I noticed the headlights dimming now and then and the ammeter showing a slight discharge when they dimmed, even when the engine was at reasonable revs. When I got home I checked the wiring all around, wiggled everything and the problem dissapeared. That is, until today when again it intermittently showed up. I noticed that when it dims, there is a slight growl or hum from the alternator that you can hear in the cabin as well as with the hood up. Also, there is a smell while it's making the noise if I put my nose down near that part of the engine compartment. I've smel…

I'm trying to track down why my Temp guage reads too high. It's usually reading about 3/4 to the right, say around 220? But yesterday I took my '71 to a Z mechanic for some fine tuning, and we proved that it's actually running around 180, by using a thermometer. Over the last 3 months, I've replaced the Temp Sending Unit, Radiator, Rad Cap, Thermostat, and hoses. And yesterday we tweaked the Valves, Timing, and Carbs. It's running great! But it's hard to just ignore the Temp guage. Is there such a thing as a Dash Voltage Regulator? I know my Roadster has such a creature, but I can't remember which guages it controls. Also, the mechanic thought that the top half o…

Can anyone tell me the location of the hazard flasher unit on my '76 280Z? I located the turn signal flasher unit on the driver side kick panel, but I can't find the one for the hazards. Thanks in advance, Spdloader
