Let new battery discharge to 12.26v. Turned on key 12.25v.Start 10.5v then 12.55v at idle.12.76v at 2000rpm12.78v at 4000rpmKey off battery holding at 12.49v.Shouldn't be jump up voltage to about 13+ to charge then level off?
IF, the battery at rest is 12.26V, it is discharged a good bit. You need to charge it, or let the motorcycle charge it, before the voltage rises to 14V+.
And what battery brand/model are you using?Patrick HayesFremont CA
My V7C recharges at 14.3V @ 3,000 rpm, and from memory the 2014 Special does the same.
An easy way to monitor is a simple gauge that plugs into your SAE battery lead. Tape it to the tank (painters tape) and it's easy to monitor for as long as needed. Battery Tender makes one'
I'll ride it tomorrow to charge it up. I assumed that the voltage regulator would feed a low battery at 13+ volts to charge it up.You could fill a book with what I dont know about mechanicing.Guzzita down the street has offered to wire up a voltmeter so I can keep an eye on things.
Both of my bikes at idle charges at 14.1 to 14.3 V, including the Griso. Your 12.5 at idle isn't right, and 12.7 @ 4000 RPM isn't either.
