   I only get a spark when I release the key off crank.

Is there power at the coil when cranking?

[dakazman]

Before about 12v. I will double check tomorrow. Measuring 6.22 ohms both ways on coil from center to -& +  . When moving distributor to open points I get good spark across points.
  Ordered coil, rotor and cap from RD .
 
  THen with all the cranking water pump main shaft started leaking.
I can’t win!

Better it leaks now than later.  All part of the fettling phase.

Measure your coil's resistance across the "+" and "-" terminals.

[dakazman]

     JB, going back to yesterdays question 10.98 volts on + coil side in run position .... ZERO when cranking.

  the coil thats in now 12.59 on p and s and 0.01 ohms across , yesterdays was 6.22 p and s  OL across

5 to 4 ohms is a good choice for points.  3 ohms will work but your points won’t last as long.  3 ohms works well with Pertronix.  6 ohms is a bit out there.

0.01 ohms!  May I suggest either a metering range error or a cheap meter?  Cheap meters ar usually way off in the resistance measurement.  Voltage is not that great either.  I have seen them 15% off.  That’s 1.5v+ when checking the charging system!

You’ve found the problem now.  Fix that and you’ll have spark.

  The 35 year old Sperry has been acting up after I lent it out. Maybe I should also change the 9v battery. The harbor freight feebee has been working better. I’ll dig out my Simpsons too .What is really nice is working with test light’s which are frowned upon for commercial aircraft. You are allowed to use test boxes that have calibrated bulbs.    Your suggestion to use test lights. 👍👍Using two, one one each side of car is helpful.
    The new coil, distributor caps , rotors and a slew of new rubber connectors . Also a variety of bullet connectors.
  The new water pump is due tomorrow.
      While sitting and looking at the wiring diagram I see that the ignition switch should be grounded.
Mine is just laying there on the carpet.🤔🤔 another question I have is what is the internal connections through the start relay  w2 connection.
  I’ll also be double checking the ignition switch to harness connections , heavy spade connections with rubber boots that are not shown on the wiring print . See pic. Maybe the spades are just laying next to each other.
Tomorrow is another day.

The ignition switch would only be grounded for a “key-in-ignition” warning buzzer.  Nothing to do with its real function.

  Took the day off , a little under the weather, I think it’s a Chinese flu called ,”Dragon Ass”.

But seriously, getting better and ready to get going again. I think I used more sick days at work in one year than 5 years retired.

   Even though I hooked up the new ignition switch incorrectly, I'll give myself a trophy for finding it.   The new switch has no labeling of the connectors that i can see and I think in my defense that I used the wire coloring that the switch came with. only swapping out my original harness wires to the switch.
 I believe that was my mistake. Terminals 1 and 4 were swapped, now when I go to crank, I do not loose voltage. Correction, the white term wires were on the wrong terminal and with all the interruptions I'm surprised I wrote this.
  I would have tried to start but severe thunderstorms are overhead as hurricane idiada approaches.
   I will also add a lead to term 4 in red wire with a bullet connector for some later addition. getting gid of the spade terms and replacing with bullet connectors will be a plus.
  I just want this to start. I will video it.

I wondered if you would be affected by the hurricane. Stay dry

And congrats on finding the switch miswiring.

[dakazman]

  Thanks Kendo
   Looks like just the outer bands skirting the coast with no significant winds. Hopefully no Tornados, that are the real threat.
  also, I'm wishing all Floridians a safe outcome.

Yes! All you in Florida stay safe!!

[dakazman]

BDA ,👍👍
  Here are some. Current state of things.
My new water pump came in along with some items that died last week . My GMC van ignition color broke off and the power window motor main gear sheared and glass dropped down. The water pump can wait until after engine break in. 🤞🤞
  Made an adapter for the crankcase filter.
 These spade connectors not shown on the S2 wiring diagram need to be converted to bullet connectors.

   I Have Spark!
   Spent the day or as many un-interrupted hours going through the start sequence through the ignition switch.  The S2 and other wiring diagrams may be wrong, switch terminals are labeled 1-2-3-5 .
 My moss motors switch pictured had the term 3-5 switched. So if you buy a new ignition switch make sure your leads are on term 3 not terminal 5. so change your prints terminal,.. 4,... which is NON- EXISTANT to term 5
   I couldn’t tell if these connections were good so I cut them out and inserted bullet connectors instead. After doing these changes I have a very loud audible spark. 😀
   I added the red wire for future connections.

   Tomorrow I’ll open my garage doors and push my baby outside and attempt to start.
  Maybe I can get my wife to go shopping so she doesn’t see all the smoke. My MGA with all the WD40 in it after starting I couldn’t see in a one car garage , hopefully that won’t happen again.
