Electrical issues are not that bad as long as you keep the magic smoke in the wires. If the issue changes when you manipulate the switch, it is a likely source. When the turn signal is in the left position, it breaks the contact for the left brake light. Conversely the right brake light contact is interrupted when the turn signal is in the position to signal a right turn. If the contact is broken in the middle position, the switch may need to be cleaned/adjusted. Since you went through the hazard switch/brake light/turn signal analysis, I assume you also found the guide on cleaning the turn signal switch. It's not that daunting of a task. Just be careful with the tabs. If you need a replacement, I'm sure that either Dave Irwin or I could help you out. Dave probably has more time than I do right now, so he'd be the better alternative.

Internally regulated alternator with an external VR is bad mojo. It is frequently accompanied by overvoltage conditions. Going from 14.5V to 17V will result in a 17% increase in current through a circuit. A good multimeter is your friend. I hope nothing was damaged.

That sounds about right. Keep in mind that the wiring diagram is NOT even close to a scale drawing.

Okay, I was looking from the top down and saw the gauge illumination first. I hate it when they duplicate wire colors like that.

How far from the fuse did it change color? RL should be for gauge illumination.

I guess the next question, Jim, is "Can Buna-N be milled down to size from a bar?" Chas, do you have any idea?

Only if you let us know what resin it was.

Dave Irwin has retro-fitted taillights with arrays of LEDs.

If you measured that with a thermometer, yes, that is probably too high. The correct thermostat is Nissan part number 21200-V0105. You can remove the thermostat and test it. It should open at 170 degrees F (or is it 160?). Directions on testing are in the FSM.

That's too bad. I was hoping they found some lying about. If it sounds too good to be true, it probably is too good to be true.

I saw this on eBay: Nissan Hitatchi Su Float for Datsun 510 Roadster Z Car and Others | eBay

If you are worried about your temperature, measure it with a thermometer. Most likely the gauge is not calibrated.

Here's a link to all of the details: Caffeine and Octane Atlanta's Best Car Show

That can be arranged some time. If you make it down to Caffeine & Octane some time, there's usually a few early Zs around. The next one is July 7.

Yeah, it only took 5 seconds for me to keep on moving when I saw this. It can't be too far from me, but I don't have enough curiousity to waste the petrol.

Are you in the Cumming area, too? I'm in Northeast Forsyth County. From the description, it sounds about like a parts car.

I would have to take a look at my stock to see exactly what could be blocking the action of the switch.

See page FE-5 in the 1976 FSM.

In the states, it's on TV this time.

Welcome. In its stock configuration, a 260Z had dual Hitachi carburetors that were a modification on the Skinners Union (SU) design. There was no turbocharger. There have been many turbocharger kits on the market. Are there any sort of identifying marks on the manifold to indicate its manufacturer? I'll pass on addressing this. Pay a locksmith. To learn more about your car, download a copy of the factory service manual (FSM). The link is below. It can help you identify what the previous owners have modified.

Actually, the wiring from the 72 is different in many areas including around the fuse box and steering column.

Where is the car located?

The swap for the 73 240Z, 260Z & 280Z is something I'm going to be looking at in the future. I am interested in getting better integration with the intermittent function. At least I can test my theories out on the 240Z & 260Z.

Thank you, Mike. Now that I have a better camera and a lot more switches to play with, I was thinking of re-doing that one. I liked your animated GIF, too. I agree about not flattening the rockers. That won't improve the operation of the switch.
