Not sure but it looks good to me.

Using a multimeter at the battery, what is the voltage for each condition.  Dash meters can be inaccurate.

I went through the same recently. Dave is right about using the multimeter at the battery. My gauge reads 15+ volts but I'm getting 14.8 at the battery. Doesn't seem like much of a difference but when it gets up to high it can boil them.

And 14.8 is too high.   14.1 +/- 0.3VDC is normal range

ok I tested to day and @ battery with RV running I get 14.2 volts so all is good thanks to all replys
