A while back I upgraded to the 60 AMP alternator with the internal voltage regulator. I had never spliced the yellow wire under the passenger seat and decided to look into it today. I know if I search the site long enough I would find what I am looking for but for some reason I am not locating the correct post. I have two 6 pin connectors under the seat. One is fully populated and was not plugged in to anything. The other only has three leads and I beleive that this contains the yellow wire I need to get rid of or at least run somewhere else if I want the brake light to go off and on as it should. For now I am just trying to get the battery from running down every co…

Hey guys, I've been overhauling most of my electrical ignition lately and wanted your input on ignition coils. Right now, my car has a generic looking black ignition coil that has been there since I bought it a year and a half ago. I don't think that there's necessarily anything "wrong" with it, but I was wondering if there was a noteworthy improvement in using new or different coils. I do have a pertronix ignitior installed currently. I see there are several options for coils, from the pertronix flamethrower models, MSD, hitachi, etc, etc. Is there a best option when it comes to coils?

I need some help. My stock ECM for 1976 was burnt so I ordered a used one off of ebay. The part number (green color sticker) on the ECM matches the stock. ( A11 600 000) But the pin settings are different. TOP - Stock BOTTOM - eBay replacement Can I use this or do I need to find something with a same pin set?

Hey Guys, Since my alternator died early this summer, I upgraded to a shelf brand alternator, which I'm pretty sure is 60 amps, but still externally regulated. I had not replaced my regulator. This of course fixed the whole not charging thing, but I really don't see the electric system performing any better than with my old alternator. Is it possible that the old regulator is negating the advantage of the larger alternator? How much of an improvement can typically be expected with a new internally regulated alternator of the same amperage? Rockauto's 280zx Reman Hitachis are running a fair $50, and I could probably redo the wiring myself and skip the $20 adapter. Edit: A…

Hello, I recently converted my '73 240z taillights and light harness to a 280z taillight. Today I wanted to check the wires with an ohmmeter to make sure I soldered everything correctly. So I disconnected the body harness from the passenger compartment and pulled out the old voltmeter/ohmmeter. Everything worked fine except for the black wire. (ground?) After looking at the wiring diagram it seems that the black wire goes to my rear defroster. Sure enough I traced the black wire from my taillights to this black wire: I can see where the female end plugs in my rear defroster, however, where does the male end go? Also, I dont have another female connector/wire to go ont…

Having issues with a start switch I believe but need some wisdom before I decide to replace it. I've performed the seat belt interlock removal on my 260 by removing and jumping all the appropriate relays but now when my switch is in the ON position the starter engages. Does this sound like a switch issue? It worked fine before I pulled the car off the road, possibly have something simple hooked up incorrectly? Thanks for any input. Dean

I'm not sure how long I've had this problem, I don't drive it at night too much. Last evening I noticed my dash lights weren't on when it got dark enough to tell. I came home and realized the PARK lights weren't working either. I have constant power on the green/blue park light solder spot, no power at the the green/white dash light solder spot. If I jumper to the dash light solder they work but the constant power to the green/blue park light solder has me confused, which is easy to do with wiring. Can anyone offer me some ideas? opinions? facts? '77 280Z, build date 09/'76, I've been reading Z'sondabrain thread. Thanks for any replies.

Hello all! Purchased a pair of brand new Koito Headlamp Sealed Beams from my Nissan dealer and they are marked on the back 6024LH and rated at 24V 75/55W. My original headlamps are marked 6012 and are rated at 12V 50/40W. Could someone in the know please explain what the difference is and any compatibility issues there may be whatwith the different voltage rating. The microfiche suggests that this new pair is compatible with its former number, part number 26705-89905. Any input would greatly be appreciated.

I have a '72 with a brake light problem on the driver's side. It does not do it all the time, but sometimes it will not light up when the brakes are applied. I know the bulb is fine. Oddly, it seems to fix itself after I turn on the emergency flashers. I suspect a poor ground, but have not been able to find where the ground to the body is located so I can clean it up. The circuit diagram shows the ground somewhere in the passenger side rear of the car. Anybody have any thoughts on this? Thanks so much!

So as I posted before I have an early 260z that sat for 12 years. At some point several parts were stolen off of it. At the same time somehow the steering column cover left the steering column and landed in the hatch. Well now it has the following issues. First when you turn the key forward the fuel pump comes on power gos to the coil, but not much else no headlights, no turn signals no brake light. Turn to start and nothing happens, instead figuring it out for now I just ran a button to the starter, now once its running I have brake lights, turn signals, but still no headlights or wipers and only a gas gauge and a speedo. I always have interior lights and choke light. I…
