Was heading to the Colorado ZFest the other day and all of the sudden my AC and fan blower quit running. It was a very hot day and had to roll the windows down to survive. I have checked both inline fuses (20amp) in the wiring harness behind the radio and they are both good. Can someone tell me what these two fuse supply power to? Got the fan out and it checks ok. How do you trouble shoot the resistor for the fan speeds (see attachment)? What other steps do I need to take to find out why the fan now has no power at any speed? I'm thinking there is a problem on the positive feed to the fan motor somewhere. I did notice that one of the inline fuses had gotten hot and actually was welded to the wire. I had to wiggle the fuse to get it to come loose. The end of the fuse holder showed high heat but the fuse had not blown, all though the fuse element was warped.

I can't seem to find Jay Zink on facebook. Any suggestions?

Zed Head, So do I interpret the centrifugal advance as such. If we look at the curve that indicates 1000X 5 deg. Does this mean that it advances 5 deg for every 1000 rpm. Thus at 1000 rpms would we have 5 deg advance and at 2000 rpm we have 10 deg advance and at 3000 rpm we have 15 deg advance?

So has anyone converted these centrifugal and vacuum advance curves for use in the 123 ignition? If so, could you please provide the data points? Curves.pdf

Thanks Zed Head. The tutorial is a bit confusing. Has anyone converted these two curves. If so, what data points did you come up with?

Zed Head, So what would the data points look like for these centrifugal and vacuum advance curves.Curves.pdfCurves.pdfCurves.pdf

Not sure where you could get springs. Sorry.

The kit I purchased was from Motorsports Auto. I had to remove all of the spacers so my head did not hit the roof. As mentioned, I want to contour the seat foam so I sit down in the foam and not on top of it. The foam is very stiff and does not conform to your body. Looking for suggestions as best method to contour for foam.

I purchased a seat foam kit for my 1972 240z awhile back and find it to be too stiff. Has anyone trimmed the foam to make it more comfortable and plush. I was thinking of taking about removing about 1 in from the seating area so that you will sit down in the seat more. What techniques have been used to trim this foam.

Has anyone found a good cruise control for the 240Z. I installed one on my 1972 years ago but it quit working and am looking for a good replacement after a recent restoration.

Have replaced all rear brake components and now seem to get squealing from rear brake shoes. Any suggestions on a cure? Seem to be able to hear it right before you come to a stop.

Thanks. Just wanted to make sure that I had them in the correct position.

Does anyone have a picture showing the proper position of the leading and trailing rear brake shoes for a 1972 240Z.

I finally just used some adhesive to hold the molded foam in place at the arm rest area. I also placed some additional foam under the middle of the seat area where a gab was created after pulling the two sides into place. This seemed to work out well.

The black area is the metal frame where the molded foam does not cover the arm rest. Yes, it has two channels, one on each side. However if you pull one side to cover the arm rest area it uncovers the other side. It seems to be too narrow.
