So just a little progress of working on my 1972 240Z that I’ve resurrected twice now since I’ve owned it from 2005 or so ..it’s been a long project and not perfect but it was my daily driver . This is where it sat for 8 years untouched next to my 1988 Toyota pickup in December 2024 All loaded up for the 1500 mile return trip in my 1986 f350 diesel I pulled from a field for 500 bucks a year earlier Once I got it home I got it running pretty easy but noticed an immediate problem in the form a rattling noise from the timing cover to discover a broken tensioner and missing bolts . After that issue was fixed I decided it was time to install my big brake kit I got from a junk yard 260z about 15 years ago .. don’t know who made the brackets but the calipers and rotors are from a 90’s corvette .. 12 inch rotors too ..don’t worry about the wheel studs they have been replaced since It also needed the carbs tuned As you can see they were way off plus I discoved the carbs were loose too ..explained why the erratic idle lol I just had to get a star road shift knob Radio was full or rodent crap and figured why not add a wide band afr gauge from auto meter in its place along with my driving light switch ..I still haven’t cleaned the marker off Also had to make my own headlight relay upgrade to run flosser h4 90/100watt ralley lights It’s an L28 with N47 head from a 1979 280ZX upgrades include 45dcoe triple Webbers . Msa 3 into 2 headers msa stage 3 schneider cam along with schneider valve springs Holley blue fuel pump . Kameari Racing distributor and fidanza light flywheel with centerforce clutch . Also running a single grove dampener . I will get the engine rebuilt in the future and get it up to 10.1 cr so maybe I’d get more out of the mods I have ..but still runs great and sounds amazing .

@SteveJ You are our “go to guy” in electric issues Steve. We appreciate someone who knows more than “It bites you, but you can’t see it”…….. like me. Live forever!!!!🥳

The flasher for the hazard lights is the same type used for the turn signals. The hazard lights flasher is located at the passenger side relay panel. Since you hear a click with the horns, it may be that the horns are corroded. On my 73, I used a wire wheel on a dremel to polish the positive contact and grounding points. You should use silicone grease on those areas before re-installing to delay future corrosion. One way to reduce heat on the brake light circuit after you get the hazards working would be to swap out incandescent bulbs with LED bulbs. LEDs draw less current.

Okay, this is weird, but I'll mention it anyway. I bought a new fan blade (just like that) from Nissan and it was great - OR would have been if I had a stock radiator maybe. But I installed a Koyo 240Z radiator in my early 260. The Koyo is probably a bit thicker than stock - although there looked like plenty of room between fan and radiator. I drove my new setup a bit and pulled back into the shop. The radiator was leaking coolant. It had been hit from behind. I couldn't figure it out. (I first thought it was a defect I didn't see) The new fan had blades just a smidge longer than the old, hard blade I had been using. And they were nice and fresh and supple (well, much more so than my old crusty fan). What I EVENTUALLY found after I almost ruined a SECOND Koyo radiator: The stinking longer, more flexible blades of the new fan were flexing FORWARD ENOUGH for the tips to reach the radiator. Fast spinning nylon beats aluminum tubes and fins. (Koyo is side tank and the fan didn't hit the center, it hit the inside of the right-side tank and the tip of the blade was then pushed into the tube and fins on that side only - right next to the tank) Check the forward motion of the fan blades at speed. (having said that, I've found NO BETTER radiator than the Koyo for my Phoenix, AZ, daily driven, A/C pumping, turbo swapped, intercooled early 260Z - and I'm still using that old, hard fan... The new one is sitting on the shelf.)

I'd be surprised if you couldn't still get one from Nissan but my local O'Reilly's can get an aftermarket one in store in an hour for a stock transmission. (also, if you dig away the black goo that the two wires come out of on the original switch, you'll find a couple of brass solder tabs in there that what's left of the wire will still be soldered to. a bit of wire and a male and female bullet connector (with insulators)... Fill the cavity back up with silly cone - just sayin')

Unless you have rebuilt the wiper motor and all of that, you should throw a bottle of Rain-X in the glove box just in case. If you go fast enough it works when the wipers don't. I kept a bottle in my Hardbody Nissan when I was driving back and forth to Destin after hurricane Opal.

A fool and his money are soon parted.

Car parts manual shows as "Relay For Heat Glass"

That’s called growing Old “ Gracefully”!

@patcon send me a pm. I have a new Nissan switch

nice, thanks for the quick numbers to look up. I think this relay is the issue with too much current being pulled when the flashers were on....... Are the relay the same for series one cars and other 240z?

Stevej's recommendation for LED bulbs is spot on. I would go so far as to recommend all external bulbs be LED. If you do that be sure to use colored bulbs that match the lense color they go behind. And you will also need to replace the blinker and hazard flasher with electronic units which are available on Amazon. I used these. https://www.amazon.com/Hbxdeco-LED-Flasher-Relay-Replacement/dp/B0DBQDY9PX/ref=mp_s_a_1_4?c=ts&dib=eyJ2IjoiMSJ9.r0vtsr6gvhaP0JqIkrNNWe1VSyoKzqOmRDZMqIRm6Sx2S7hdmByoSlq5B7nnOyC4MjUdGvYR06DT5etEUXNzrXbi7AcSH8Rng3yRz4GSf1YwuYjEHcbLtbKRPcP3uDHyo1Fn9msBVau9Fk45nP6kIF-9rnZd6556d6neZaina6L_ZLR8n8uvVl9wvzzTfmPOdAe6JyV2wZsad-_tpTWpyg.1qmzhFAIKk5rXUhbY14Gkd6aGisVISftIH7AlWO7sMs&dib_tag=se&keywords=Automotive+Electronic+Flashers&qid=1756048201&s=automotive&sr=1-4&ts_id=15716621

Fraternal twins!

😝

Good information. Thanks for the followup. There was none, now there is some. Well done.

3M has always worked well for me.

As an ex fire and burglar alarm engineer... i advice you a 2 ltr CO2 fire extinguisher, they leave no recidue as powder makes a MESS! I'm surprised that halon is still available, in europe i believe they are no longer legal!! (Halon is often used, or was used in computer environments.. halon just takes away the oxigen in the air so if your ever in a room when halon is coming in, leave as fast as you can you will not be able to breath in there!! BTW, yesterday i could not react or make a new topic, maybe some russians in the lines... :-o

I managed to to find a pic of that 81 car on my PC. Cant remember where I found this but the file was named with a date of 1990 and I distinctly remember Tom telling me the car was raced until then which led me to believe it was the 08 car. Also attached are some more pics of Logan @ Blackhawk in '74. I wanna say greyghost took these too but I don't see them in his gallery here.
