Put new starter on car, starter turns great have 12 volts at coil took coil wire off cap and checked for spark when put buy intake and have spark which tells me points are ok. Still no spark at plugs changed condenser and rotor cap and tried a new coil wire to cap still no spark. What I’m I missing
correct wires and spark plug for point type ign? check spark through a plug not just the the plug wire.
Check thw wire for the "S" terminal on the starter. I think purple (if I remember correctly). That will cause a no start if loose or off
The car ran great before changing starter the old one was weak when hot so I put in a lt1 starting it and had the correct solenoid installed on it the car started right up, took it for a drive the next day and when I turned it off it wouldn’t start again. NOW I only have 5.4 volts at +on coil
Verify you have the two red wires with fuse links and battery positive cable connect to the large terminal. Yellow goes to the "R" terminal. Purple goes to the "S" terminal. Pull the wire to the coil + and see what the voltage is through meter to ground. Should be less than battery due to resistor wire (6-9V) Then crank and make sure the solenoid relay is energizing and supplying full battery voltage during crank. Also make sure points are clean.
I've put new brushes in along with a cleanup of armature commutator and starter life is back to like new. Hope you figure it out.
Does the LT1 starter have the "R" terminal? Sorry, saw you stated it had the correct terminals. Thought LT1's didn't have R terminal.
5.4 volts with ignition in RUN position, and engine off is normal for points. https://www.v8buick.com/index.php?t...ystem-function-tests-and-modification.248990/ It should jump up to 9 volts minimum while cranking.
