Charging voltage Mariner / Yamaha 55 EL

[jurgenscraft]

the volt meter connected to the electrical system shows a voltage of about 14 to 15 volts when charging . What is the correct charging voltage and has this particular motor have a voltage regulator fitted in circuit and what happens as rpm rise will the charging voltage also rise if there is no regulator fitted.

Re: Charging voltage Mariner / Yamaha 55 EL

Jurgens, I am not sure what kind of charging system you have on that motor (regulated or not). On an unregulated system, as the RPMs rise, the current output from the stator/rectifier-based charging system rise. The voltage will rise slightly also. As the battery reaches full charge, the voltage on the system will rise to about 13.5V. The difference in voltage between the battery and the charging system is proportional to the charging current.
