Alternator voltage questions

[papak]

When I hook up the battery minder to the car, it maintains the charge at round 13.5v. Once I start the car and the revs get to around 2500-3000, I am showing 15v on the voltmeter. This is with no load other than ECU and pumps. The alternator is new, a small 40 amp unit from a Suzuki. There is a 50 amp master fuse in the charging circuit. I am running a small Braill battery.

 

I have seen no issues arise from this to date other than some deformed tail light lenses (I have since changed to LEDs). I guess I could change the pulley but without some actual knowledge to base it on, it would be stab in the dark. Total miles are 1300 on everything.

 

Should I be concerned?

Maybe Mighty Mike will chime in. He had an alternator gremlin and ended up doing a pulley change...Eradicated the evil.
