voltage reading on TL 4.0

[PaulRV6]

Is it normal to show a 12.9-13.0 v reading at steady cruise going 55 mph? Had defroster on high and head lites on also.

From my experience ... yes.

Assuming you have a standard 120amp alternator, and the stock 8ga charging wire, that's close to correct. 13.2 would be better, but with age, all things "droop"

With the double fans, and having to run A/C, and headlights etc. my load got to be too much, so I upgraded the alternator to a 200amp, and upgraded the charging wire to 4ga.

Now, with everything running full blast it never drops below 13.7 as reported on the aldl data stream. No load, it runs 13.9-14.0

Normal and shouldn't be a problem.

Thanks guys, that makes me feel much better, I will cross that one off my list of winter "things to do". Thankyou again.
