Drop 3 to 4lbs of fat, and get a Lithium batt

That would be the best idea, but it just depends on what the budget dictates

Ouch Dan, sorry to here of the troubles. Hope it's charging

Eh, it's no big deal. This was one of those problems I was expecting to run into, but hoped for the best. I at least hoped it would have lasted me 6 months or so.

I did get it charged all the way and took it for about a 30 minute ride. Ran strong the whole time, no issues with the idle. Got back home and reconnected it to see the condition, back down on amps almost to where it was. It just won't produce the juice lol. I ran into this with my last Goldwings battery, and had the same kind of troubles. As long as it is running, usually it's fine. Only at idle and low RPM was it ever a problem, and then not having quite enough power to run the starter AND power the ignition. Thankfully the Goldwings came with a kick start backup. Unlike my hawk, which is almost like pushing air, that hunk of lead is like trying to push the RMS Titanic up a hill.

On the note of charging system testing. Are there any documents or does anybody have any data on what kind of AC voltage or acceptable resistance range on the Stator wires to the Reg/Rec? I want to try and be more thorough than simply see if I make more than 12 volts at the battery with the bike running.

You say eh, but...dont sound too bueno to me (Not charging).

A simple voltage test at the battery while it runs shows 13 or more volts at the battery while it is running. Not a detailed test of the charging system, but it is an indicator that it is charging.

Yeah! Sounds like a battery to me....ARH

Pulled the battery from the bike and charged it to full and let it sit on the table overnight, hooked it back up to the charger. Right back at 50 percent. Still tests out 12 volts, so this battery likely has too much internal resistance and just doesn't have enough current. When the engine is revved up the stator can produce enough to keep everything happy, but at idle its probably just barely not enough.

yuasa ?

No, its a generic no name battery. I am going to try and get an agm battery if a lithium isn't in the cards.

charge voltage should be in the high 13s to low 14s....
anything less and the battery struggles to maintain voltage...

Yeah, now that you mention it, I recall my Qlink had a similar problem - no air allowed into / past fuel cap, which created a vacuum across the fuel system, starving out the carb.
I do not recall precisely how I corrected the condition, but believe I simply "modified" the fuel cap gasket.

13.4 Volts at idle, 14.1 Volts at 5000rpm. Just did another check to make sure.

Like I said, I ran into the same issue with the old battery in my Goldwing last year, no matter how good the charging system is, the battery just can't maintain the capacity. It's just strong enough that while riding the bike it will never be an issue, I could ride for hours and it would never seem like anything is wrong. It will just never truly reach, or maintain, a fully charged state and have a low amp output. I have disconnected the charger once it reaches a full charge, wait a few minutes, hook it up, and it will start charging it again and be right back at 75% and take an hour to charge. Leave it unhooked for an hour or so and it will drop back to 50%. It will always show 12 volts at the posts.

Brondo has what batteries crave. I have a Battery Tender Lithium BTL09A120C.
