Bavaria Yacht Help! / Re: starter battery charging to 15volts
« Last post by marioxp on March 17 2024, 12:39 »measure the voltage between the sensing wire and the alternator housing (or from where it gets the negative pole) to determine what battery voltage the alternator sees. And compare it to the battery voltage. Either the alternator sees a lower battery voltage and therefore charges it with a high voltage, or the regulator on the alternator is faulty.
