Topic: blowing condensers regularly

[mono]

What is your charging system doing ? Amps and volts ? Drive it and look at the points . If there is metal build up on the negative side of points it over capacitive .If the metal is on the positive side it's under capacitive . Possibly the coil is shorting out internally . Electricity is lazy it always takes the shortest path to ground.

as far as V goes, it tests fine at the various RPM levels (per the manual).   Haven't checked Amps, though I can do that.

-- I *have* noticed a build-up on the points, but I will file them down and run it again to check that.  that's a pretty cool bit of knowledge!

 Learned that bit of info from my Auto shop teacher in the 70's . My opinion of the arcing is the condenser is not creating a proper path to ground , hence the arcing . The coil secondary is still being saturated . My fathers Model "A" had a defective condenser from sitting over the winter . Back fired none stop . Some times the quality of the parts out there has something to be desired . By the way did you mention if one or both condensers are going open

Anyone aware of ELI the ICE man?

Not me care to enlighten?

"Eli the Ice man".

    E=Voltage I=Current... L=Inductor......C=Capacitor
    ELI Inductive circuit...... Voltage arrives before Current .
    ICE Capacitive circuit... Current arrives before Voltage.

DC circuits are much easier to deal with and have simpler rules than AC circuits.  The operation of the points creates changing DC conditions where AC theory and operational become important.
While the coils and condenser don't see sine wave operation, the transitional behavior, puts it firmly in the AC theory category.

just one at a time is breaking, although it is not happening to the same "side" each time.  rode 25 mi last night - no probs.   sigh.

I consumed some points many years ago. Most of them bad quality as mentioned brand, logo as a propeller.
I think that the TEC's were replaced just for sure for the new season. At that time I did not see any difference. I learned from friends that CB750 eats points. I always bought complete plate with points and capacitors.

After reading threads on this forum I'm aware of TEC quality product.  I have reused old capacitors by the same reason as here, points with flashes when running despite not old capacitor.
