My auxiliary batteries don’t seem to be charging whilst I’m driving?

Your vehicle’s auxiliary battery system is fitted with either a 24v-24v or 24v-12v battery charger. your charger operates whilst the truck engine revs exceeds 1000 RPM. Inspect the inline blade fuses and all electrical connection points for tightness.
