70 Amp alternator charge voltage

Stanley · Guru

Hello and welcome to the forum.

The standard regulator is not adjustable and most likely the batteries are a bit down and are asking the alternator to provide this charge.
What kind of batteries do you have?

I have 4 Trojan T-105 6volt batteries. The batteries are set up as 2 - 12volt banks and were paralleled at the time. The batteries were very near full charge due to the shore power charger being turned off only 10-15 minutes before starting the engine.

Here is the link to the Trojan battery spec sheet
You will see that the charge rate is between 13.5V and 16.2V for a 12V system so it appears that everything is working as it should.

The voltage seemed high compared to what I am used to seeing for my other chargers. Thanks for the information and quick response. I'll keep an eye on the batteries and get in touch if I have any further concerns.
