Hey All In my eternal attempt for originality I am currently going over the engine bay wiring in my 09/71 240z. I have come across what I believe is a non-original relay (Bosch brand), but it seems to be wired in with original factory wiring (4 wires, shrink wrapped, factory style plugs). It is located just ahead of the windshield washer bottle (keep in mind Im in the RHD part of the world), about midway down the inner fender. It is held in place with a single, large head, self-tapping screw. The wiring seems factory and comes out of the harness. I suspect that the starter motor is wired to it. My queries are: 1. Is this a relay and is it suppose to be there. 2. What doe…

Guys and Girls, I am in a spot of bother with the new onset of rain and cold weather - my heater fan died last week with a spray of plastic bits out of the fan vents thus I have no demisting powers! Driving Melbourne peak hour traffic with fogged up windows isnt pleasant at all!!! So, is there anyone in melbourne who could help me out with a fan assembly? Soon would be awesome! Cheers Mick.

Am planning on replacing the fusible links with a gold plated fuse block, on my 75-280, California model Z. I only have 1 fusible link box, located on the relay bracket. It contains 2 links, 1 green labeled Ign, and 1 black labeled batt. Underneath this box, is a metal box, 2" x 2" x 6" and it contains a copper strip, shaped like a "m", and 2 glass fuses. 2 large gauge wires ( 8ga maybe ) one white and one white/red connect to the large metal strip, and 2 light gauge wires, same colors, connect to the 2 glass fuses. My question is : is this unit the fuse for the charging system ? Thus can be replace by 60 amp fuse. FSM shows 2 normal fusible link boxes, but this me…

It's a crazy problem car i bought but its fast so its worth it any idea of the problem would be great or just a place to start looking would be nice.

I pulled a 280zx distributor at a junkyard to throw on my L24. I've been searching the threads here and on Zcar.com and the posts said to use the ZX coil with the conversion. Since I first heard of this on the Z garage website and never saw this mentioned, I purchased the Crane cams PS20 coil from MSA. Will this work?

Hi Everyone. If I don't start my car and let it run every day the car will not start. I left for palm spring on Friday and came back today, Sunday and the car will not start. I just had it running Friday. I had a very powerful sound system installed recently and I don't remember this happening before the sound system was installed. Could the sound system be draining down the battery even when its not on? Do I need a new battery? Do I take it back to the place where I got the sound system installed? Please help. Thank You.

Hey guys, I was doing some searches and dissapointed not finding any information on an electric fan conversion for cooling. Maybe my searching skills are below par but either way I would like to know who has them, why they got them, how much it costed, and mounting/modification specifics. Oh and also the horsepower free'd up from taking the engine driven fan off? Enough to notice ? Thanks

http://www.classiczcars.com/forums/showthread.php?s=&threadid=5997 I'm getting ready to swap an '80 60 amp alternator into my '73 240 and am using Bambikiller's excellent writeup as a guide. But I have a question that I don't see answered in it. I've attached a picture of the new alternator. You'll see a yellow arrow pointing to a connection that isn't in the write up. Anyone know what it's for? The reason I ask is that I took the alternator to a parts store and had them test it. Their configuration didn't show connecting that pin and they were unable to get any output from the alternator. So I went to another store and their configuration did use the connecto…
