I have not heard from the buyer since the two minute call yesterday. I did send him videos of the car running even though he said he didn't care if it ran or not, but more importantly, I wrote that I don't expect any negotiations when he arrives to buy the car. Maybe that was a "deal killer".
Anyway, my now "good friend" Al has offered to priority mail me parts. So I'm not giving up yet.
I measured resistance of the resistors and coil and found things definitely a little off, but I used a multimeter which is not recommended:
- 0.6 ohms resistor: 0.95 ohms
- 0.4 ohms resistor: 0.75 ohms
(^^ maybe my meter just reads 0.35 ohms high??)
- coil: 1.05 ohms.
(Edit: sl113.org page says it should be much lower: "Disconnect all connections on ignition coil. The primary resistance between terminal 1 and 15 is 0.38-0.43Ω at 20° C.")
When wires are connected as they should be, I get about a max of 4.5 volts at the coil, but it drops to about 1.5 when I start cranking. Of course the car isn't starting, or my post would be very different. (Edit: per the sl113.org, this doesn't look terrible: "Switch on ignition and read voltage on voltmeter. Rated value: 2.6-3.5 Volt")
Here is a video of me testing the ignition coil for spark. (I know I should have at least tried an unpainted surface, but this was about all I cou reach while turning the key and holding the ignition wire.)
The spark looks weak to me. Any thoughts?
Now here's the part where you guys may want to hunt me down and shoot me.
The plugs that came in the car were platinum of some store brand plugs. I can't remember, but not Bosch or NGK or Champion. (I may come back and edit with what exactly they were.). Also, I'm pretty sure that the plugs that came in my 5.0 SLC were also resistor plugs. That's what is in there now, and the car ran the same with them and the new points before I discovered the hacked up ignition wiring.
Now in addition to the plugs, I noticed that the spark plug wires are also 1k ohm on the boots.
So it looks like I'm forcing a lot more resistance in this circuit than I probably should be. I don't it is going to make the difference, but I plan to put in the NKG bp6es plugs I just bought and see if I get spark, you can see that I'm at least getting something at the ignition wire. Maybe I should try various spark plugs outside the engine too.
