There is a black wire going to each socket. Check the resistance from that wire to ground. It's always good to check the reading of your meter with the leads touching each other first. That gives you the resistance in your meter. Your reading on each socket should be pretty low.

That's about what it would have cost for me to send one ball bearing to you. Are you sure you don't have a grounding issue? Measure resistance to ground on each side. They should be about the same.

Yes, that was an interesting work around to say the least. ::

If the 72 has decent carburetors, swap them over to the 71.

The dash & engine wiring harnesses are a write-off. I helped Charles with replacing the battery, but the starter was on it's last legs. He got it to fire a couple of times briefly, but it wouldn't stay running. Let me know what parts you won't need off of the 72. I might be interested in some. If you're on Facebook, track down the Georgia Z Club & Georgia Datsun Owners groups. There are quite a few good S30 owners in Georgia.

I know this car. I hope you have plenty of time, patience & money. Did you try to get that parts car in Dawsonville, too, or do you have another parts car? Where in GA are you?

The gallery pictures do not have the right detail. Look at http://www.zhome.com/Buying/1stGenWhatToWatch.html and http://zhome.com/Classic/CommonZRust/RustPrevention240Z.htm and take pictures of the areas described.

So, am I correct in thinking it was a polarity issue with the LED bulb?

Very true, Dennis. In California & Arizona, a "rust-free" example not running is worth far less than a similar car in the East or Mid-West.

What is the VIN on the firewall? You need to post pictures, especially of underneath the car to get more than wild guesses. Running will increase the value, as well as fixing the known issues. (I state it only because it's not obvious to some people.) I have a guide to repairing the turn signal switch on my blog. I also have a detailed write-up on the entire circuit there. I would inspect the master cylinder and brake booster for the leaking, especially if there isn't a puddle of brake fluid underneath the car. For the lack of fuel, try replacing the fuel filter and blowing out the line to back to the tank with some compressed air. Keep the pressure low on the compressed air. It shouldn't take too much effort.

My first guess is there is something wrong between the ignition switch when it's in the ON position and the coil. The emphasis is on the ballast resistor. If you know how to use an ohmmeter, take the wires off of the resistor and measure. When the key is in the START position, you bypass the ballast resistor.

Chet Wittel was talking about this video today. The car making the pass in the grass was piloted by John Williams. Chet said John's crew told him it was the last lap before it was the last lap.

I took my Z to the memorial service for John Williams today.
