I had to switch to that battery to get the engine to start. Just like the alternator on a car the rectifier is supposed to charge your battery while the engine is running.
The outboard motor is not a type of charger but it can provide energy to your battery if you know how to charge trolling motor batteries with an outboard.
Outboard motor not charging battery. Make sure to also charge this battery off of a battery charger before each use. NEVER jump-start a battery while an outboard engine is running. This can cause damage to the rectifierregulator.
Always use a battery charger to charge a battery. If no battery charger is available the rectifierregulators Red wire. My outboard motor is not charging the battery.
I only get 126 volts at the battery at any speed. I would like to make repairs myself. The motor is a Mercury 60 HP 1995 model.
I see two boxes or modules that go to the stator. The charging system on outboards can work in one of a few different ways but the power going to the assessories will always remain in a regulated range usually not exceeding 128 volts. The charge portion of the stator on most outboards produces AC that varies between 12 and 16ish volts.
The first part of a solution therefore lies with a bridge rectifier and capacitor to make use of all the available current. This will provide more power but the voltage is still not high enough to effectively charge a battery. To solve this problem Ive devised a simple circuit which costs less than 6 to build.
Reconnect the lighting coil to the RR. Measure the battery voltage. Should be 127 volts if the battery is fully charged.
Start and run the motor at a fast idle. If the battery voltage rises to 130 or more volts the RR is good. Most outboard motors even those without an electrical starter can charge a battery just like your cars motor can charge its battery.
Large displacement outboard motors do this as a rule. The major components needed are. Generator coils that create electrical current unregulated AC from the motors rotation.
Regulatorrectifier to convert the coil output into regulated DC current suitable for charging the battery. Do outboard motors charge battery when running. Yes they do charge.
Pretty much all outboards that have an electric start will re-charge the battery as it runs. Deep cycle batteries are more for things like trolling motors and pumps. The motor is usually ran from a cranking battery.
Click to see full answer. It would automatically close to charge your outboard battery when the engine is running or when there is sufficient output from the Rutland but would automatically open again when the engine is stopped and the Rutland is not charging. The trouble with electric outboards is that you have to recharge the battery.
With a small petrol engined one. 10 amps into an 18 Ah battery could be a problem. Exceeding a 5C charge rate could be tough on the LiFePO4 battery.
Check your batterys specification for the maximum allowed charge rate. Playing devils advocate that 10 amps would likely be seen at the battery only if the battery was at a very low state of charge. Disconnect the battery cables at the battery and clean them well.
Read voltage of the battery without the engine running then reconnect the cables and start the engine and run around the lake for a few minutes and recheck the voltage at the battery if it is higher than engine off you are charging. If not you probably need a new rectifier. So it is definately not the fish finder running the battery down.
I had to switch to that battery to get the engine to start. I have not tested anything with an ohm meter. To be honest I have no real experience using one.
My next weeeknd off I work every other I will get one rounded up to see what I can check. But would definately assume at this point that the motor is not charging the battery. If your motor has an electric starter troubleshooting the battery is not unlike a car.
If you turn the key and only hear a clicking it might be that the battery is dead. Look for obvious causes. Boats should be rigged with two batteries one isolated from everything else on board so that it retains its charge to start the motor.
One of the more common reasons with an outboard boat engine is that the rectifier is not working correctly. Just like the alternator on a car the rectifier is supposed to charge your battery while the engine is running. If this little unit is not working correctly then it wont be able to convert the AC Alternate Current to DC Direct Current.
Shortly after turning the engine off the green light will go out indicating that the batteries are isolated so the trolling motor wont run down the starting battery. The ability of the alternator in the outboard engine to keep the trolling battery charged is dependent on the size of the alternator and how long the outboard engine is running in relation to how long the trolling motor is. Outboard motor battery charging.
Another EE question from a non EE. I have an old outboard motor 75HP. It starts and runs once started.
The problem is that it does not charge the battery when running. I understand there is no generator and the charge is backwards through the magneto that makes the spark into the battery. A battery fully charged has a reading of about 126 volts.
You should connect the voltmeter to the battery as before but not the charging voltage and this should be done after charging the battery or jump starting the car. 135 to 145 or more volts at idle should be produced by a charging system that operates normally. The original rectifierregulator has been updated to a different part number.
Hopefully for improved reliability. As long as the connections are clean and secure I dont think there is anything that can damage the component. By connections I mean the battery cables at both ends and the grounding wire to the RR connector.
Do Outboards Have Alternators Do They Charge Batteries. Almost all outboards that have electric start and that were built in the last 20 years will have either an alternator or a stater that charges the battery when the engine is running. At what capacities and loads they charge the batteries is another thing.
EP Carry is a light and effective electric powered outboard motor for a dinghy or small boat. With a complete weight of 21 lbs. For motor and battery pC its mild enough to raise and carry without difficulty on and stale your Typical deliver to shore use consequences in 2 to three days of run time with out the need to charge the battery.
The outboard motor is not a type of charger but it can provide energy to your battery if you know how to charge trolling motor batteries with an outboard. Using an outboard motor is an approach if youre figuring out how to charge trolling motor battery without shore power. Well provide you insights into how to charge a trolling motor battery from the outboard motor.
At the battery you should read 125v on a fully charged battery without the motor running. With the motor running it might jump to 145v as it charges the battery. Turn on everything that is normally running while you are fishing radio depth finder graph live well lights etc.
Measure at the fuse block and the battery. I have a Honda 90HP 4 stroke that will not charge the battery - engine will run all day but battery slowly discharges- battery checks mout OK. Multimeter on battery shows voltage while engine running is same as with engine not running.
