Just rebuilt my L28 and put a new alternator. Hooked everything back up as before and now my voltmeter is pegged all the way to the +. Also my left headlight is so dim as to barely see it. Furthermore the belt even though it was tightened properly was squealing like it was overworking. I put the old alternator back on....still had the problem. I believe the alternator was hot also, but that could be engine temp. What's the cause?

Hello, I am new, both to the forum and z cars. I have a 1973 240z as far as I can tell (not worth much) a reasonably stock car. I am hoping someone can shed some light on this, so here is my problem: 1) Battery will not charge, replaced alt and volt reg still getting 13 volts at bat. 2) Headlights will not work, nor will dash lights. I suspect the switch or see #3 3) 2 fuses blocks on the fuse panel have no power. Here is the pic. I am missing the original fuse box cover so I am not sure what these two are (see pic) I have a feeling that they are all related. Thanks for your help!!!!

I did a quick search and did fine some info. on the fuseable links for the 280, I was wondering if the parts could be purchased at a Nissan dealer and if any one knew the part numbers. I noticed this weekend that the plastic coating on the black one in my car is cracked not burnt just cracked. thanks,

I have a problem that someone else must have had. The headlights and brake lights on my 70Z work but I don't have any parking lights, tail lights, side marker lights, or turn signels. The back up lights and flashers work. I have replaced the combo switch and checked all the fuses. All ok. I have pulled apart and reconnected all the push to connect wires that I could find and still nothing? Any ideas? sawdust2005

I am in the middle of restoring a 74.5 Datsun 260Z (found in a farmers field, next to a Willys and a 67 vette). I'll start off with what I have done, to give you guys an idea of what is going on... Engine was seized, so I pulled the engine out, squared up and honed the block, added all new inners (saved the originals) cleaned up the automatic transmission, changed all the fluids posible, tore the molded deteriorated interior out, and I have the interior 85% back together. The car is drivable now during the day, and the engine runs quite well, and now I'm down to figuring out the little problems that just are a pain in the butt. From my other 260Z and various purchases (th…

I've got two problems with my tach and I haven't seen any discussion here on these problems yet. If I've missed them, someone please chime in. If not, then let the discussion begin. First problem, if engine speed changes rapidly, either from a gear change or goosing the throttle, the tach does a pretty large-scale bounce. Probably up to 4-5k then it bounces down to approximately the correct reading. Secondly, you'll note that for the first problem, I say 'approximately' because my tach seems off by about 1000 RPM. At idle, barely ticking over at about 500RPM it reads 1,500 or so, and on the highway in 4th at 70, it reads 4,500 or so. I'd like the tach to read correctly, …

I have a 1976 nissan 280z And I cant get it to start i replaced the injectors ,fuel pump ,fuel filter, spark plugs and cables the only way acan get it to runn for about 30 seconds is if i put fuel directly into the intake but my fuel pump does not get any current and i connected straight to the battery but it wont keep the car running i dont have any current to the distribuitor and i was thinking that it might be the transistor ign every fuse has been checked and all of the are fine i cant keep on guessing i think that i checked every possible cable and fuse.

Alright everyone- I'm not getting any spark and I can't figure out which way I need to hook up the wiring harness to my coil/ ignition. I removed the engine out of my 240z along with the coil/ ignition/ distributor. The motor came from a 1983 Datsun 280zx its an L28 (non-turbo) It has an electronic distributor not points. So I have an L28 motor from a 280zx going into a 75 280z/ I know its stupid pointless but I changed my mind about selling my 240z and ended up having to use the motor I have. Also, the L28 is now running a triple carb setup, not fuel injection. First question: Do I need to change the distributor to get spark? Or will the electronic distributor work? Sec…

Like the owner's manual says it does. Or are they supposed to? Not a huge deal, but it would be convenient... It turns on and off in the conventional manner. Before I start investing any time in this, are 280Z dome lights intended to stay on for a bit once the car is shut off/door opened etc.?

Hi guys, I went through the wiring diagram a few times and need your input. a. 1976 280z - I studied the wiring diagram for 1976 and it looks like a lot of wires' colors are wrong coded. I am trying to determine what the cut wire is in Picture1. I am assuming this 6 wire plug is for the whole engine harness? On my car's diagram I can't find the Green with Red stripe wire (BE-94). b. My water temp/oil pressure/voltage gauges don't work. The water temp gauge goes to maximum indicator position. The FSM suggests ignition relay, voltage regulator and bridging the thermal transmitter's yellow wire to see if the gauge's needle fluctuates. I checked the continuity off the t…

Ok I have my fathers 1983 280zx and need to get the turn signals to work now I have changed the Relay on the drivers side. And went all through the car tracing wires from the back. They all look good. Now the hazards work but I can't get the turn signals to work. Please help I don't know what to do. My husband thinks it is funny when I am working on cars but I want to do it my self. He sits with me and rally just watches. Now I will be getting in the repair manual tomorrow but not sure it will cover this repair.:stupid:
