Charging System

Think push is not happening when talking volts. Can it push the starter over. May not be the charging, could be the way the battery was prepped.
Stator sends AC up the wires.
Rectifier does one thing. Regulates volts.

Formula for charging a battery. Say it's 12 of 14amp rated. Move the decimal point to the right and it now reads 1.2 or 1.4amp hours needed to charge it; using a charger rated for 1.2a or 1.4a. So you have to find a rated changer that matches the output of said rating of the battery.

In other words, you can't use a charger rated at 1.2a and try to charge a 1.4a rated battery. The answer is I believe is if formula is to change the battery for literally 12hr on a 1.2a rated changer, then add more time reaching 1.4. Whereas, using a 1.4a rated charger you'd calculate less time reaching 1.2a rating.

Trickle charge is if the battery can hold 12.8v. It can deplete a whole lot of push and recovers back to12.8v, it says ideal battery.
With a volt meter, use this to watch for the Rectifier to work. At idle the RR kicks out 14+ volts. If you read 15-16v, this says stator is good, RR can no longer regulate volts.

1. PUSH - Do you have it? Then it's the battery. Could be its age, to how it was prepped for service.
2. RR - Does it read 14+v when running?
3. Stator- Then it's not the stator. Does the battery read steady the same volts when running or not? Then it's the stator.

With volt meter at the battery posts. Start the engine. Push drops to 11v and recovers with the blink of the eye. Battery says good. If it reads 10v or below, and recovery is slow, battery is can no longer store push, or volts= Replace.
 
Just a report back, tested the stator and regulator, all tested fine as did the test at the battery.
Of course after I reset the circuit breaker.

I’ll keep an eye on that, if it trips again I’ll replace the regulator.

Appreciate everyone’s input, very helpful.

Me personally i have no use for a circuit breaker on these bikes...i got rid of the circuit breakers and put 30 amp inline fuses in its place on 3 of my dogs that have a ehc and i do the same thing to any other dogs that i work on.....the main reason if it blows the fuse i know where the problem is....circuit breakers can reset thereselves or a person can reset it and then more problems happen....if the voltage regulator is over charging and the circuit breaker gets reset them it will finally pop the ehc... i also put 20 amp inline fuses between the battery and the ehc so the battery or voltage regulator cant pop the ehc and it also helps me know where the problem lies there also
