Hey, I'm just a few miles away. Though my address says Gainesville, I actually live in Forsyth county.

Sorry, I don't know anything about the cars other than what I posted. I'm sure I'll run into the guy again since we are working on the same project.

Actually, I was in Virginia on business yesterday, and another person attending the meeting is a member of the Tidewater Z club, who owns a twin turbo & a 70 240Z.

Well, that does sound like you threw parts at the problem. Did you happen to inspect the old switches to see what was wrong?

IIRC, the bulbs for turn signals/running lights and brake lights are dual filament bulbs. I am not familiar with the EZ harness, so I don't know if it is wired for dual filament bulbs. You may wish to do a "stare & compare" with the wiring diagram from the FSM.

1. Did you or a previous owner change the headlight switch? Why was it changed? (Did the responsible party diagnose a fault or start throwing parts at the car hoping it would be fixed?) Is it correct for your year? 2. Have you examined the fusebox, including the backside? Corrosion in the fusebox can increase resistance in the circuit, causing a hot-spot that promotes further corrosion or even melting of the plastic in the fusebox. (Been there, done that, got the t-shirt) 3. Are you sure all of the wiring harness connections for the circuit are in place? It's not unheard of to have one become disconnected/loosened as you are wrestling with putting in new parts or performing other maintenance.

What is the condition of the water pump & the belt that turns it?

Hey, Doc, do you live in the North side of town? I might be able to help you with inspecting a Z if you aren't too familiar with the breed.

A bad voltage regulator can cause the battery to drain. It's easy to check, too. Just look in any repair manual: Haynes, FSM, etc.

It is possible that someone may have the information you are looking for. It would be to your advantage to state the year of the car for which you need a wiring diagram.

Call it brands, call it product lines. Call it swiss cheese. None of those examples you cited show any time that a car company has changed the brand name. All of those brands contained different product lines, even if they were only differentiated by badge engineering. Maybe I was just confused by your spelling of Infiniti.

Apples and oranges. You are talking about different product lines. Carl's statement was referring to changing the brand name, though I lean toward Alan's statement that the Datsun name shouldn't have been used in 1958 when the brand came to America. Of course, it doesn't help following up one mistake with another.

Why did it fail? Was it visual or tailpipe? Do you have any test results? If you don't, I think you can get an unofficial test (not reported to the state) to see where you're at. It can mean the difference on whether or not you're tagged as a gross polluter. Also, what shape is the car in with respect to the body, interior, and drivetrain? Could you use that one as a parts car if you bought another?

I thought it was an incredible event despite the rain on Saturday. I even managed to fine a Corgi die cast of a Bob Sharp Racing Z. Like BR-Z said, the Mitty has almost every kind of racing you can imagine. He did leave out some of the types of cars. There were also Formula 1, IRL, Champ, and WSC. It wasn't all just historic and vintage cars. Spec MX-5s and Spec Mustangs were racing, too. The MX-5s were more interesting than the Mustangs, though. The Mustangs had what sounded like stock exhausts. There is no way a V-8 racing motor could be so quiet. I think the best experience was the 1 hour enduro with the WSC, GTP, and GT cars. From the rumble of the Chevy V-8 to the chriping of the turbocharged Porsche's blow-off valve, it was a delight to the ears as well as the eyes.

I first found out about it from a Grassroots Motorsports email about a month ago. I'm sorry I didn't mention it back then. Gwinnett Place Nissan bought some tickets and re-sold them through the Georgia Z Club.

Is anybody else going to the Mitty at Road Atlanta this weekend? I managed to convince my wife we need to go on Saturday and Sunday.

Go to the Z Club of Texas website and check their sponsors.

It would help if you said what year Z you purchased.

I think the car has been on eBay a few times. I know it has been the topic of discussion at ZCar.com. That's the risk of customizing a car. Beauty is in the eye of the beholder, and you may never find another eye like yours.

Did you check the distributor and cap, too? Do you have a spark going to the cylinder?

Thanks, Stephen. I might set my Zs up like that. I want to put in battery interrupts, and a side post design is more conducive to that desire. I don't want to put the interrupt across the battery hold-down frame.

Stephen, do you have a picture of the side post installation? I'd like to see that.

Try this.

Check your fusible links.

Headlights: 1. There are no factory installed relays in the 240Z. 2. Get a wiring diagram. Look at the link below for Blue's website. Heck, even a Haynes manual would give you some idea of how the circuit is wired. Use the diagram and a multimeter to determine where the circuit functions. 3. Search this site and Zcar.com for all sorts threads on the same subject. 4. Clean the switches. Just be careful not to lose any parts.
