This problem just arose yesterday. When I am driving at night with my headlights running and I hit the breaks, for a split second all the lights inside and out of the car dim. The volt meter drops to about 11 and the turn signals are really slow when the breaks are pushed in. This only happens when the clutch is in and the car is running at idle speed. If I hit the breaks without using the clutch, this problem doesn't happen. Basically if the car is at less than 1500rpms and the breaks are pushed, I am robbed of this power. My question is, does this sound like a weak battery or a bad alternator? Its also been giving me some trouble starting too, which is why I am t…

Interior light 1 2

When I open my doors, the interior roof light does not go on. However, when I push the light to manually turn it on, it does light up. I pushed both pin switches on each door, they seem top move in and out fine, but don't activate the light. Why do you think it doesn't light up? I am missing something? Is there another switch someplace that I don't know about. I know in most cars there is a swicth for door/off/on. Thanks guys.

Well after a few days of tracing wires, checking fuses and basic exploring, I have come the realization that my interior/dash harness is shot. The previous owner has cut/spliced and basically turn my wire harness into spaghetti. Is there a source for a replacement harness for my interior/dash that will not require a small bank loan to finance. I am really looking for plug and play if I can get away with it. I understand enough about the electrical system to be dangerous but not enough to troubleshot. Any help would be greatly appreciated. 1977 280Z---on its way to becoming a daily driver (I hope)

I'm having a little electrical problem and kind of need some help. yesterday i was driving the car and everything was fine until everything just shut off. engine died, lights went out, no voltage, nothing. i check the battery, terminal connections, and everything was fine. i have some voltage now but its weird. sometimes it would read 12v and when i turn the key to the on position it does the normal buzzing sound. when i try to crank it, it just makes a clickick noise and everything shuts off. voltage down to 0. and after that the voltage would slowly go up and reads about 8v sometimes 6v and sometimes 12v. when i try to use any electrical component the voltage drops dram…

I am trying to get my headlights working but im really not having much luck getting them working. I checked all the fuses, they where good. I replaced the headlights with new ones and that didn't help either. I checked for voltage at the plug for the headlights at the front of the car but i got absolutely no voltage there. What else is there to try?? Thanks

I just got this Optical trigger ignition at a local you-pull junkyard off a 260Z. The guy charged me $6.95 with tax. I took the distributer,coil, and all the electrics you see here. It came with a epoxy type coil. The transister has a Motorola symbol on it. I took it home, cleaned the contacts, hooked it up to 12 V and gave it a spin. It ZAPPED the S**T out of me... I'm guessing they were pretty reliable. Thanks, Doug

What might be common between the headlights & windshield wipers besides the switch itself? It's past 2:00 AM and I have to get up at 5:30! I've spent the last few hours working on my 240Z. I just got it back from my buddy's shop. I traded some computer work for tuning my ZTherapy SU's and installing a 5 speed transmission. I have to wait until business is slow for the work to get done but it's worth it. Anyway, I had installed Dave's headlight harness prior to driving it down to the shop and they were working. It's been about a month since I dropped it off. I installed the tail light harness this afternoon and it worked great. BUT, now the headlights don't work and …

Hey all, I just purchased a 1977 280z. The car runs but it looks like a monkey wired it. The previous owner must of been an idiot. The major problem I have is a lack of windshield wipers and horn. I need both of these to pass state inspection to put my Z on the road. When I got the car the previous owner had replaced the ignition switch with a brand new OEM unit and the wiring harness under the steering wheel was exposed. The seems to be no loose wires but then again I honestly do not know what I am looking at. Any ideas where I might go to start debugging these problems. The other major electrically issue I have it all my gauges with the exception of my Speedo do not wor…

Hey, Just finishing up my final little things to get this car on the road. I was checking my lights and determined that my brights werent working properly. My driver side light it burnt out. The passenger side will light up, but will not switch to brights. When I hit the switch, the light get slightly brighter, but it is just as if more current is going to the bulb and its not switching bulb circuits like it should. Anyone have ideas how to fix this. I have the electrical diagram from chilton but its pretty much useless. I konw that on old VW vans goofy things would happen if you had a burnt lightbulb. Will this fix when we replace the lightbulb, or do I have to …

Hi Guys, I have had the usual issues with left indicator working intermitedly and solved this issue by opening the moon shaped switch that the indicator stalk goes into and cleaning it up, strectching the spring and re-installing. At the same time I was hoping to fix the switch for the hi/low beams and damaged it beyond repair. I was wondering if this same switch is found in a 280ZX or any other Datsuin models? It was available new from some Datsun suppliers up until a year or so in Australia so new is not an option anymore. The switch I'm talking about is the square one pictured below with the long plastic "pin" sticking out!???
