PD9260c 13.48 volt charge instead of 13.6?
Just got my new PD9260c converter installed. Checked my battery voltage before plugging in, 12.67 volts at batteries. Plugged in the 9260 and got a reading of 13.48 volts at batteries. Manual states i...

The stated output voltage is the converter's setpoint, i.e. the voltage it tries to output at its terminals. As others have said, measuring it at the converter output terminals is important if there's an appreciable charge current flowing since there can be some voltage loss in the wiring.
If there's a significant charge current or DC usage in the RV, the converter also may not be able to put out enough power to reach its setpoint voltage. It would basically be operating in a current-limited state (or perhaps a power-limited state, which is rather similar). This is perfectly normal and expected. (Typically the house loads are not near the converter's output capability, so it would be mostly the charge current that enters in here. If the batteries are low, it could be substantial.)
If the wires are indeed aluminum, and not tinned copper which can look similar, I would suggest replacing them for that reason alone. Aluminum is more prone to fatigue, and tends to oxidize/corrode at connections particularly with dissimilar metals. Tinned copper wiring, on the other hand, is perfectly acceptable and arguably superior to plain copper wiring.
