The alternator takes the energy from the crankshaft and turns it into the electricity that is stored in the battery of your boat. Obviously, batteries sometimes fail on their own–but a bad alternator can actually cause the battery to drain because it's failing to recharge the battery.

The alternator rotor carries a rectifier which transfers the voltage through the shaft into the alternator field coils. The adjacent diagram shows a marine alternator which is marked by the red coloured circle and an arrow pointing towards it.

Keeping Up a Charge – The Basics of Your Boat’s Alternator. The charging system in most sailboats consists of batteries, alternator, voltage regulator and the connecting wires and cables. The job of the charging system is to replenish the batteries and to provide current to existing loads in the boat at the same time.

The alternator passes this electricity to the battery, which gets charged, and powers all accessories. An alternator is what keeps the lights, the gauges, the deck fillers, and several other parts functional on your ship. Furthermore, for this particular reason, your battery lasts longer despite powering all the features.

The Benefits of a High-Amperage Alternator on Your Boat . Safely run a suite of electronics with help from a high-amperage alternator.

Max Charge and ARS-5 regulators both sense battery temperature and can regulate charging voltage accordingly. Alternator temperature sensing can also save your alternator by reducing output if the alternator overheats. Both alternator and battery temperature sensing features require optional temperature sensors (MC-TS-A and MC-TS-B).

The way a stator works is similar to an alternator but also not the same either. Jet Boat Stator Vs. Alternator. An alternator will charge batteries, and so does a stator. What makes a stator different is that a stator is more for maintaining a charge, and an alternator is for charging completely.

Boat #1 Engine Room Temp = 162.4ºF. Boat #2 Engine Room Temp = 171.1ºF. Boat #3 Engine Room Temp = 132.5ºF. The alternator on boat #3 is going to have a much better chance of staying in a safe operating temp range than the Boat #1 or Boat #2. A cold and a hot rating are simply the short term outputs at 6000 RPM and the rated temp.

How do I wire my marine alternator? Many alternators require ignition voltage to initiate charging. You must verify that all required connections are connected to the proper terminal and have the correct voltage in order for the alternator to operate properly. Below you will find the most common alternator circuits used on marine applications.

1 Simple Test 2 Test 1: Check Voltage at the Battery 3 Test 2: Check Voltage at the Alternator 4 Another Response 5 Appendix Using the panel voltmeter, the reading should be around 12 with the ignition on, not running, and no other loads. When cranking it may drop down to 8 or 9 volts. Once started, it should almost immediately jump up by 2 volts or better to around 14 volts (you might need to ...
