By the way, Bruce, I believe I may still have a set of flat tops taking up some space in my garage...

Give it a try. Here's my latest selfie. Funny, the camera on my phone stopped working just after I took this photo.

Can you attach a better looking face to my name?

Go to Knoxville where there are a bunch of UT fans wearing an ugly shade of orange, or go to Atlanta a see a bunch of great Z cars. WHY do you suggest there is a decision?

Congratulations on the new job. I hope it's less travel than the old one. Just make sure you build a big enough garage for your Zs at the new homestead.

I guess the Jims will outnumber the Steves.

It's less than 2 hours from the host hotel. https://tinyurl.com/ycd56s74 Blairsville is about an hour from my house.

That isn't what my experience was. For the 73, the rear bumper was easier than the front. You can use the 73 rear bumper brackets on the early rear bumper with no modifications.

To elaborate on Zed Head's response on coil vs ignition module, the coil is an energy storage device/transformer. It can take 9 (ballast resistor present) or 14 (operating voltage when the alternator is turning) volts DC and step it up to 20,000 to 40,000 volts DC depending upon the number of windings in the coil. The lower voltage side of the coil is an open circuit. The negative post has no direct path to ground. This is where the ignition module comes in. The ignition module detects the position of the distributor, usually with an optical trigger or magnetic reluctor. At the appropriate time, the ignition module closes the path to ground for the coil. With the completed path to ground, you have current flow through the low voltage side of the coil and a spark at the spark plug.

Driving or flying?

Actually, the drive is to Helen back. ?

Well, it's just about 3 weeks until opening ceremonies for ZCON 2018. Who is in? By the way, the typical high temperatures for mid October are in the low to mid 70s. Lows are typically in the mid 50s to upper 40s. It will be great driving weather for those of us bringing S30s.

That is correct. I did NOT have to modify the 70-72 bumper brackets to fit an early bumper to my 73.

To be clear, you can use the 70-72 bumper mounting brackets on the 73. The mounting holes for the early brackets are there, and no modifications are needed. There are reproduction mounting brackets available such as from site sponsor @zcardepot.com https://zcardepot.com/front-bumper-bracket-stainless-steel-240z-1970-73.html

To put the early bumpers on my 73 I had to do the following: Buy a set of early bumpers. Buy a set of early bumper brackets. Remove the old bumper and bumper mounts I did a "dry fit" and determined I needed spacers on the sides. I installed the bumper. It's not too difficult, but my next door neighbor did lend a hand here and there. https://fiddlingwithzcars.wordpress.com/2014/01/20/installing-the-front-bumper/

The thing about a two-post lift is that some people don't have the clearance in their garages for either the height or width. I have a scissor lift (https://www.gregsmithequipment.com/Atlas-TD6MR-Portable-Scissor-Lift) in my garage and park my Z over it. It rises higher than Carl's lift, but it isn't suitable for transmission work. (I can change the driveshaft while the car is on the lift though.) It's great for brake/suspension work, rotating tires, getting at the gas tank, etc. Between the 2nd Z, tools, shelves, and all of the other stuff in my garage, I don't really have space for a two post lift.

From looking at the 73 wiring diagram, I would guess it has something to do with the seat belt buzzer, though the wiring diagram only shows 1 green & 1 black wire. Also, it should only buzz with the ignition in the ON position. If I am correct, the buzzing and lack of power are unrelated. Unplug the buzzer and use a test light to see if you have 12 VDC to ground on any circuits in your fuse box.

Here's my $0.02. How often do you get your car industry news from whichcar.com.au? (or motor1.com - the other site I've seen with this information)

Green is usually associated with the wire coming off the ignition fuse. It provides power for the turn signals among other things. I scanned various FSMs, but I did not see this connector. Please supply the year of the car you're working on. There are wiring differences between the various years. The device in question is a relay. I can tell that much.

Year? Photo of the offending part? Wire colors?

I could have sworn @Carl Beckbought a low rise lift for his garage that could operate with a drill and work underneath. I cannot find the post, though. I assume you have a garage, but I figure that being in Redondo Beach it wouldn't be a big garage. Edit: And then I found it: http://becksystems.com/garage/EZCarLift/EZCarLift.htm

You can get a copy of the 72 Owners Manual from Amazon. I provided a link.
