High voltage???
I had to install a new alternator because the old one was dead in car and on tester at parts shop.
Now I think I'm getting to much voltage.
With the rpms above 2000 or so I get 15 volts with nothing on.
I put 2 new voltage regs on so far with the same 15 volts.
If I run the fan and head lights I get 13 volts so that's what I have been doing.
I checked all connections and ran a ground from the volt reg and I still get 15 volts.
Is 15 volts a problem?
Checked with dash gauge and hand held volt meter.

Mine charges at a steady 14.5 volts across a meter. I don't think 15V is anything to be concerned about.

Where are you seeing 15 volts, from thr alternator or at the battery?

Is the battery fully charged? Are you looking at the dash meter? Have you checked at the battery with a good gauge.

I'm checking with a multi-meter at the battery and I get the same reading on the dash.
Battery is reading 12.7-12.8 with the car off so I think the battery is fully charged.
All high readings is above 2k rpms or so.

That sounds good. I always worry about low voltage with lights, air, two blade fans and small fans pulling air out of trunk. God help me if I turn on the radio!?;);)

Voltage
My new one-wire alternator puts out 13.8V without accessories on and 12.8V with headlights, etc on. Running Autometer volt gauge. I wouldn't worry about your voltage.

How did you get a 1 wire alt to wire up? |

I have 12.6 volts with the car off. 15 volts with the car running. Drops to 14.5 volts when the radiator fan turns on. 100am - 1G (3 wire) alternator with external regulator.
Never had a battery or electrical problem, but I routinely keep it on a Battery Tender when not being driven.

A no load voltage of 13.5 to 15.0 volts is considered normal.
A one wire alternator connects directly to a battery source.

I get 15 volts while running with a 1 wire, haven't noticed any problems. Unlike the 3 wire, the 1 wire will discharge the battery if left connected.

Thanks everyone, I will consider it good and stick with the 3 wire.

15+ volts on the dash mounted voltmeter. 1 wire setup. With everything turned on, 13+ volts.
