![]() You merely plug them into a wall plug in the garage after your boat trip. I have seen bass boats and others with dual batteries that have a "charger' permanently mounted in the boat. "Smart" merely means that it is 3-stage and it varies the voltage according to the state of the battery. Its the kinda thing you have in your basement so you can charge your boat and tractor batteries in the Winter. The ALT output lead was connected to the input of the isolator and no other wires were changedĬlick to expand.The "battery chargers" that I have are all 120 volts. Note: I had a 3-bank isolator installed by Formula which charged all banks using an isolator. The ALT output would go to 15.2V which its not designed to do Also, only the bank the sense is connected to, will be the only Bat that will see the 14.5V. Moving the sense lead to the battery will increase the voltage output to get the batteries to see closer to 14.5V, but this also may cause an issue with the ALT. With the isolator the starter post and the motor would only see around 13.8V (14.5 - 0.7) ![]() ![]() The ALT output lead normally goes to the starter post, but with an isolator the output would be connected to the the isolator. Each diode has a voltage drop of 0.7VĪ fully changed battery should read 13.7V after being removed from charge and having sat for couple hoursĪlternator and battery chargers would normally output around 14.5VĪlternator output is controlled by the sense lead which is the purple wire which is part of the engine harness. ![]()
