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.

Well, if the wiring diagram in the Clymer manual is correct, the horn relay has a green wire with black stripe, a green wire, and a green wire with a white stripe. However, it doesn't help narrow down the location.

Here is my 2¢. First, either take apart both your switches (On/Off and Hi/Low Beam) and clean them or send them off to Dave (Zs-ondabrain) for his cleaning service. The contacts will get dirty/corroded over the years. Next, look at the electrical system for corrosion. The Datsun Z Garage has good information on that under the section "Z problems". After that, consider upgrading the headlight circuit to relay operation. You can buy the wiring from Dave as well. You can search on this site to see that Dave has lots of satisfied customers.

Given the choice of checking out the car with someone from this site and using an appraisal service, I would choose the former. With the appraisal service, you may or may not find someone who knows Datsuns, especially given their age. Even if they know old cars, are they familiar with old Japanese imports? Every car has its weak points. Would Joe Blow Appraiser know about the rear end clunk? U-joint play? Specific rust points?

FYI The original poster's car is a ZX. I attempted to reply to his original post yesterday (placed about an hour before the start of this thread), but the electrons vanished into the ether when I tried to post my reply. The good news is that I can now add to check battery cable resistance to my list of diagnostics.

Well, it's three hours each way for me. Unfortunately I'll have to take a pass. I need to keep on top of the Road Atlanta schedule. That is a lot closer to me.

E, I have to go on my typical rant. Rarity does not equal desirablity. I don't think you could pay me to own a mint condition unmolested all-original Pinto or Vega (Okay, maybe a Cosworth Vega...). How about a pristine Yugo? Fuggetaboutit. On the other hand, look at the first generation Mustangs. They are considered desirable. They were produced in numbers that overwhelm the production of Z cars. After all from 64 1/2 to 68, there were somewhere near 2,000,000 Mustangs that rolled off the assembly line. There are still a lot of survivors, and they are still on the market. Compare the number and prices of first generation Mustangs for sale compared to S30 Datsuns. Having said that, I do think the 2+2 prices will start to creep north as the supply of coupes dwindles, but the 2+2 prices will typically lag behind the coupe prices. I wouldn't be surprised if on average they continue to lag far behind coupe prices.

Lee, is that why you want to come over to look at my 260Z? I can assure you that it's not the same one. On a serious note, you may not want to know what happened to the car. I suggest to try to start fresh. Who knows what may have been done to the car after you sold it? Have you ever seen the shows where they let people see houses they sold after the new owners redecorate? It's not pretty.

I found it on Sunday at my local Wal-Mart. It wasn't with the rest of the Hot Wheels. They have an area for the "Collectors". That is for people (like me) willing to pay $4 for a $1 toy.
