Hi all, Question: Does anyone have a bench testing procedure for a stock '72 radio? I'm hoping to get the radio in my '72 240z working. I've removed the radio and found some burned/corroded speaker wires which I've sorted out. The antenna switch works fine (goes up and down with the switch). The blue light does NOT turn on. The radio is a Hitachi KM-152OZC. I just saw one on eBay for $2,000, so yeah, I'd like to fix mine. THANKS

Hi all, a problem came up the other day (the left turn signal quit working) and I'm not that up on electronics in the car. The car is 1976 280Z (11/75), all original has had no modifications to electrical at all. 53K miles on the car. What I know so far. 1. The blinkers hazards (4 way's work). Even the left side. 2. New bulbs as of this year. 3. Right turn side works and at the correct blinking speed. 4. I did take out the turn signal switch out and it looks and seems ok, no wear or burning. 5. I do have a service manual and tried to see what it could be (not much experience in reading electrical), it looks like there are two flasher units…

Okay, so today I re-turned the ignition lock key a little to quick, and suddenly nothing anymore. I know this problem is posted before here. Battery is good. But nothing is working. Where lies the problem ? Fuses are all OK. Amp meter ? I don't know how the 240z is wired exactly, since its been a long time I have been doing anything electrical on it. Gr Bart

I am to un-upgrade the fusible links in my ‘78 280Z back to the OEM fusible links. Seems everyone goes the other way, so I would think the old fusible links should be around?? Any help sourcing the OEM fusible link bases (2) and holders would be greatly appreciated. The covers and wires are readily available. thank you!!

Hey, I just picked up a 1973 240Z and after taking it out on it's first drive I noticed the turn signals didn't appear to work. After leaving the car parked in the sun for an hour or so when I drove home they were working again After I got home I was testing all the lights and noticed the left rear turn signal wasn't working. The hazards worked as well (all 4 corners). I couldn't check the brake lights at the time At some point I was testing the turn signals with the lights on and the turn signals flashed slower and then stopped altogether. The hazards still work. I tested the turn signal flasher relay by hooking it up directly to the battery and after some…

Hi Guys, The car i bought has some custom work done on the stereo and OEM antenna. The 3 blue wires with a switch do not work. How does the antenna normally work on the 280z? I mean the switch has two positions and I would expect it is an UP/DOWN operation and the antenna can be stopped at any position (i mean half up vs full extended) can someone confirm? Currently it is connected to the stereo/radio and when i turn the unit on it just fully extends automatically. May be thats why the switch does not work.

I just installed this controller today and works great with the electric fan. I installed the sensor in the thermostat cover, I did install the controller in a weatherproof plastic box in the engine compartment. this model came with the 1/4" npt sensor and also the radiator probe sensor. I only used the 1/4" npt sensor. it will turn on at your set temp and then off 5 degrees lower.it does seem off by 6 degrees, as I have it set at 183 degrees for on and off is 178 degrees. that is comparing with a digital thermometer in the top of the radiator. it can be adjusted from 110 degrees to 230 degrees by 1 degree increments. I can see when the water pump is at full flow in the …

Hi Guys, i parked the car last night and all seemed to be fine. Today when i tried starting the car the starter did not engage. Mine is 77 Auto and seat belt is engaged and i also have a new ignition mod and like i said it worked last night no issues. I noticed when i took the key out, the rear red lights kept ON. Played with the brake pedal a bit but no effect. I had to disconnect the battery for now. Where should i start? somebody seen this before?

HI guys '72 240Z Just added a tail light relay kit to my car and while I had things apart I cleaned up the turn signal switch. The headlight switch looked brand new and worked well before installing the kit so I left it alone. I reassembled everything and now when my headlight switch is off my parking lights stay on. Position 1 is as it should be, parking lights on. Position 2 powers up the headlights. I have hi and low beams, the turn signals work as they should. Looked at a lot of wiring diagrams but can't figure out what I did wrong. Any suggestions? Thanks,

does anybody know where to pick up a rocker switch for the console? I am looking to install the fog lights and would like to install the rocker switch in the spare location next to the hazard switch to control the fog lights. I am not sure if a regular rocker switch will fit?thanks
