  1. look at photo I sent on Monday, Green is + , white /blk stripe is (-)
  2. I was reading your post from the beginning and have a question. When you said the car wouldn't start did you mean the engine wouldn't turn over or it turns over, but will not run? Also the relay you showed is a Bosch std 30 amp relay that is used for everything and mostly in alarm systems. If this is hooked to your start switch the PO might have tried to by pass the wiring to the starter because the car wouldn't start. I had this problem with my 75 and have seen it on more than 5 cars over the years. look at the crude diagram I have drawn. I currently employ this relay because it eliminates running a high current through the ignition switch that if shorts in the steering column causes all sorts of problems.
  3. Here's a couple of pix of the coil/res. Let me know if you need more
  4. Sorry to digress, Ing module for 75 280 . Also be careful with the carparts manul as it covers several years. 75 has only one fuse link box and the manual shows two. I have a 75 and it 's different than the 76 in many ways. Do you still need a photo of coil and resistor wiring?

  10. Try JK Electronics in Westminster , Orange county CA or the best is Torrance electronics in Torrance Ca on Carson street. Also" ALL electronics" in Van Nuys Ca.They are on line and only take electronic orders.
  11. Well , RS is long gone or at least what use to be the Tandy Co. Look around in your area for an old electronics store. They are still around, but only a hand full still survive. Where are you located? If you get parts on the web they only want to sell quantity, shipping is high, and takes weeks to receive.
  12. The clock pendulum should work no mater what position you put the clock in. Your problem is the caps and the transistor. Replace them with exact values as marked. If you replace just one then everything might return to normal and then later the other cap(s) may fail. If the coils are good then everything should work. DO NOT start bending or tweaking anything. If you replace the components, 3 caps and transistor, the clock will work as usual. As I said before if you over heat the coil wires you can destroy the coils. There are other problems with the 76-78 mechanisms because plastic gears were used. However, replacing the 4 components mentioned should correct the problem.
  13. I should mention that the plires,used as a puller, is only to break the surface tension of the corrosion between the clock hands (Tin) and the clock shaft (brass). Once you get the hand(s) to slightly move you can remove it with your fingers. Also, the plires are used to remove both clock hands. I know that some hands can seem like they are welded on. In that case you can use 1/2 drop of "Blaster" penetrating spray and let it sit for a couple of hours (don't get any on the clock face). Just before you try and remove the hand apply heat from a hair dryer or heat gun and it will let go. Also, Blaster is the best stuff on the market and it penetrates all rust. I've remove many rusty exhaust manifold bolts / nuts that normally would break. "Blaster" and heat works every time.
  14. When I mentioned removing the clock through the glove box I was referring to the 240Z. I always remove the 280z clock through the vent under the 3 gauges. You remove 8 screws and the clock slips right out. You didn't mention , but is your clock keeping good time? The way to adjust the clock hands is you have to remove the minute hand form the clock shaft. If you remove the shaft from the main clock gear and reinsert it you can damage the main gear. I enlarged one of you photos you posted and I believe there are two cracks in your main gear. The reason you shouldn't remove this shaft from the gear is the end of the shaft is knurled and there is an interference fit between the knurled shaft and the Nylon gear. The shaft is inserted in the gear when it is removed from the injection mold. The warm nylon conforms to the knurling and locks the shaft to the gear. Fast forward 40 plus years and the Nylon becomes brittle. You stress the Nylon when you remove the shaft and potentially crack it. The nylon is really stressed when you reinsert the knurled shaft as the knurling will not go back to its original position in the gear. When I say stressed it cracks and the teeth on either side of the crack separate.This changes the spacing between the two teeth and the mating gear can lock up or slip. Not much you can do now, but I wouldn't put additional stress on the shaft by pulling it out. If you want to get closer with your clock hand alignment you need to remove the minute hand with a puller that doesn't apply stress. Using the credit card and screw driver method is what pulled the clock shaft out of the gear. If you look at the photos you will see the puller I made. All you need is an old pair of needle nose pliers and a bench grinder. To insert the minute hand back on the shaft what I use is a tongue depressor(modified). As far as the rubber gasket goes just flip it over 180 deg and use it. The only function it serves is to push the bezel /lens out 1/8 inch for the alignment of the clock set knob. None of the mechanisms are hermetic. If the 240z clock mechanism was hermetic the clock would last years longer. You can remove the lens, but you risk damage to the lens and the bezel. Mask off the bezel with painters tape and polish the lens. The polish I like is Flitz, Semichrome, and Brasso. They all do a good job on the plastic.
  15. It looks like you are right on . Of course it's hard to tell from the angle of the photo. If you set the hands to 6 o'clock it should look like a straight line, is it? You have to remember that the clock hands are very wide and there is gear backlash. The best you can set the time for is + 10-15 seconds. Trying to manipulate the gears once assembled is the hard way to go. Same thing like removing the 240 clock. Why access the clock by removing the heater controls when you can go through the glove box!
