So monitor my alternator output thru the Bluetooth connection on my Victron DC to DC charger shows my alternator voltage fluctuates between 12.4v and 13.7 and sometimes a bit higher. So my DC to DC charger will cycle on and off quite a bit due to low voltage. Pretty sure this is not a new problem, Verified by the voltage reading on my USB chargers. Varying rpm doesn’t seem to have an effect.
Could it be a faulty regulator or alternator or something else? How could I go about testing?
I’m not really a fan of crawling in beside the engine when it is running.
Standard equipment Motorola 55 amp alternator and voltage regulator on a Lehman 120.
