What Should A 24v Alternator Charge At. Reading should be between 138 144 v for a 12 volt system 278 284 v for 24 volt systems. Reading should be between 138 144 v for a 12 volt system 278 284 v for 24 volt systems.
It leads to the alternator and connects to the terminal labeled B or Bat Place the sensor on the end of the red wire from the multimeter onto the metal alternator terminal. A simple way to use the 12v lights with a 24v system and not worry about the battery charge balancing is use a 24v to 12v inverter. Wire x2 12v alternators in series to produce 24v power.
Ive seen a lot of videos where people mount charging systems in their boats and plug them in to charge when they get home.
This circuit creates an offsetting voltage at the lamps. For maximum battery life the alternator charge should be sized to not exceed the recommended charge current. For others its normal to see as high as 16 volts for long stretches. The potential conflicts with power demanded by the vehicle the desire for redundancy and increased capacity led me to the second solution.
