Need to pick up a new ballast resistor, it's about a twenty minute drive each way. Is it safe to temporarily attach a jumper wire across the resistor, or will it fry my coil and points ?

On my 73 240Z my headlights seem to work properly with the stock wiring, but it seems backwards. When the lights are turned on the black wire gets power while red/black is ground when using low beams and red/white is ground when using high beams. This causes problems when trying to upgrade my lights to use relays. This can't be correct can it? And if so, what could be causing this?

In the yellow and black wire loom going to the temp sensor, my black wire is not hooked up. I thought it went to the distributor. (Spade connector for the old points?). I'm running some electronic distributor of some sort. I checked the wiring and engine diagram but didn't see it marked anywhere. Just curious. Car runs fine. On a side note, over the holidays I got the: - Tach to work - Brake lights and directionals going - Cigarette lighter working - Found out what's wrong with my headlight switch - New Brake booster installed (Warning Don't lose the clip on the large pin for the pedal. Luckily I found it. Seems the 73-83 pin is the s…

I fugured out that te scale on my Gas gauge is about 1/4 tank high, so I usually run out when the gauge reads 1/4 full. I cleaned the connector for the fuel-level sender last summer, which is when It started reading off. I also cleaned the connector at the gauge about the same time. So either I need to clean the connector and the connections on the sender itself, or the gauge itself needs to be adjusted. thx

I'm now moving onto the electrical system of my 72 Z. None of my lights work except for hazards on the left side. All my gauges work, my ammeter is always a little to the right, unsure if this is good? My voltage at the battery is 13.5 and goes up when I rev. My brake light on the cluster works when the e-brake is up. There's a few wires not connected, most of them I have figured out. I wanted to know how to keep the wires from dangling all over the place, most of my wiring is connected. Can someone upload some photos on both ends of the firewall(interior), by the steering column, center console on how the wires are tucked away? I know on the right s…

Hi everyone, I see that some people refer to grounding to the frame/chassis. Then I see some refer to ground to the body/firewall. If the engine and trans or both are grounded to the frame, would one still need to ground to the body (shock tower, firewall)? Finally is 8 gauge insulated wire sufficient, or are the braided grounds straps better? Howard 1974 260z

I was going to order a new lens for my map light in the heater console since mine is missing. Does this piece just pop in place? My switch has the spring in it, so i'm assuming that is the spring they are referencing? I thought this is the rocker type push button map light. One side is fixed so to speak and the return of it to flat is done via the spring loaded switch? http://www.240zrubberparts.com/apps/webstore/products/show/4424748

Maybe this has been posted before, not sure so I thought I would share. I recently picked up a second console with a defroster switch and choke plate that I needed for $75. I figured a spare console would be good anyway. When I got home I realized the switch was frozen. I put some lube in it, freed it up and cleaned it with electrical spray. Tested for continuity and nada. I recently rebuilt my headlight switch and wondered maybe this was similar. Sure enough it was. With a small screw driver, gently pry each side out and slowly lift it out. Be very careful not to lose the small plastic tip and spring. I did! I had to rob one from an extra defroster switc…

I decided to pull the dash out of my Z to fix some hack job wiring done by the previous owner, and I'm confused as to where a few of the connectors go. I'm working on the part of the harness that drops from the center of the dash down to the fuse box and choke/defroster/seat belt light, and the PO cut some of the wires so things are difficult to figure out. Where do these connectors go? I suspect that this connector goes to the choke switch. It's wiring is red/blue stripe and black. The red/blue is snipped, and it looks like the rest of the wire is in the harness closest to the connector (as pictured). The choke switch connector is red/blue and red, so this worries …

Fog lights???

Did US cars come with fog light option? On my 71 I notice the hole above the flasher for it and by the horn wires the red and black wires look factory tapped still. I checked the owners manual and there is no mention of fog lights. I'm assuming I can source a fog light switch and the wiring provisions are in place?

Right TS quit months ago. Tried sandpaper and VOM but no luck, no time to delve into it. Been using hand signal and being extra careful changing lanes. Now it's working again. Maybe the gremlins have seen the error of their way and are trying to make amends. A "new dawn" in the way mechanical things interact with us, maybe. There might be an explanation, but I've got nothing.

Does anyone have any experience with the mini battery booster packs that are popular now? The older ones were about the size of a small briefcase and weighed like a toolbox, but these mini things are smaller than a carton of eggs, and boast up to 100 Amps! they usually have a 5V USB outlet for a phone, and a USB inlet for charging, LED lights (red, flashing or illumination, etc.) but no hand-crank or air compressor like the older bulky booster packs. It would fit well in the Zed almost anywhere, like in the tool bin, but you'll still need to charge it occasionally. It might be a good thing to have in the boot of the city car for the winter, but since I keep m…
