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

Well, I finally have the car running but now it appears I have an electrical issue. When the battery has a full charge the car starts just fine but the alternator gauge has a slight negative reading. After running for a bit and shutting it off, the car tries to start but since it has been running on the battery there's not enough spark. I have a brand new alternator that clearly isn't charging the battery when the car is running. Any suggestions as to what the problem could be?

Bit of a wiring rookie here. I found a Harada semi-automatic antenna on EBay as a replacement for my current antenna (broken mast) and have a question about the switch wiring. My current antenna has a 3 pin connector to the switch wire with Blue/Red, Blue/White and Black wires. The new antenna has a different type of connector and just two wires, Blue/Red and Blue/White. My plan was to connect the two switch wires for the new antenna to a 3 pin connector that I purchased so I can use the original wiring that runs to the switch. Am I right in thinking that the Blue/Red and Blue/White wires on both antennas would serve the same purpose? Also, I'm not sure what to do a…

Hi Guys, Anybody knows what u call this thing? There are two of them one on the red wire and one on yellow going to the stereo. My Stereo stopped working all together and i saw one fuse fell out due to loose holder. The other is totally damaged. What u call these? Also, the fuse says 250v 3A? are the fuses both same as i misplaced one 🙂 why does it says 250v?

My ignition switch will only go in the on and start position. Of course this led to a new dead battery. I was wondering which fuse box circuits should see power ONLY when they key is in the on position?

I have a .5A draw. Pulled all fuses one at a time Alternator and starter have been professionally rebuilt . Replaced voltage regulator which I thought was the issue . It clicks when connecting the battery cable . Old one and the new one . It also gets warm . 2 bad regulators ? When I pull the field plug it quits So my white 12v from the starter is intact . I have 12v at the plug for the regulator ( solid white ) I have continuity from the WB at the regulator to the WB at the field plug . That makes me think the regulator is not supplying the 12v at the plug .

Hi All, 240z Wiring harness , L28 two questions below on grounds. The EFI set-up is complete. Worked with Haltech remotely engine is running but chasing down a vacuum leak. Also having a weird issue with the electronic distributor connection to the ECU. Losing the grounds randomly. First questions: Need to add a grounding strap from the chassis to engine block. Why, attempting to move my star ground (all required ECU ground connections) to another point (currently chassis). Where is the best connection point? The engine bay harness is a stock 73 240Z. Is the chassis ground under the battery box off the harness a good point for a chassis to engine block s…

I have a 6/70 that I am putting back together. I reinstalled the dash, harnesses, etc. The front & rear turn signals work, hazards, all dash lights, headlights, taillights etc. I can hear the flashers clicking. Everything flashes for the turn signals and hazards except the lamps in the instrument panel. I don't know if they ever did work. I never drove the car. The hazard switch does not appear to be factory correct (I think it came from a (~7/71) so I wonder if someone plowed this field before me. Is it safe to assume the instrument lights run off the same wire as the front turn signals? If the front turn signals work but the lamps in the dash don…

Good Evening Everyone, So I went to go for a drive last night, and when I turned on the headlights I noticed that the dash didn't light up. I got out of the car and noticed the headlights were on, but the tail lights and side markers were not. Very odd... I checked the fuses and noticed the applicable fuse was burned out. I turned off the headlights, replaced the fuse, turned them back on and within a few seconds the fuse began to smoke and burned out again. Maybe an exposed wire was touching something it wasn't supposed to? I shut it down, went around to the front and noticed a cable just dangling touching the ground (please see first picture) I've t…

Just putting this out there for people to remember when diagnosing electrical issues, I have seen this on a couple of cars now. First a 260Z with no turn signals. The hazard lights worked. We looked for continuity from the switch to the bulb socket. The test failed, so I took apart the connectors to see where we were losing signal. All of the harness sections tested good. We plugged the harnesses back together, and the turn signals worked. Next a 280Z with an intermittent temperature gauge. After testing for a while with mixed results, I separated the dash harness from the engine harness, again with inconclusive results. After I plugged the harness back togeth…
