    No tach,no charging

    Are you saying that because perhaps there is no standalone ground wire? I am not aware of any R/R that does not have a ground of some sort.

    Starting engines with jump box & dead house batteries

    Is anyone suggesting that electrically powered devices be kept turned off to the maximum extent possible in order to help the alternator last longer? Maybe run a live well pump only every so many minutes instead of continuously. Come in before dusk so navigation lights don't need to be...

    Starting engines with jump box & dead house batteries

    Is the thinking that boats should not have lights, radios, gyros, pumps, trim tabs, MFD's, etc. installed as this equipment would need to be powered by the alternator of an outboard motor?

    Starting engines with jump box & dead house batteries

    "An alternator is a compact belt-driven generator that’s installed on an engine to convert mechanical power to electrical power. That electrical power helps recharge a connected battery and, more and more, is being used to directly power onboard systems."...

    Starting engines with jump box & dead house batteries

    Mechanic sounds like the type that cautions not to store batteries on a concrete floor.

    Starting engines with jump box & dead house batteries

    Batteries are being charged and recharged every day by most every type of motorized vehicle. Strange sticker. While at the same time an alternator is powering more and more electrical components in cars, trucks and boats.

    Starting engines with jump box & dead house batteries

    The mechanic does not understand basic electricity. Sounds like he is regurgitating something he read on the internet. The world has been jump starting dead batteries and using the alternator to charge them since alternators (and older style generators) were discovered.

    No tach,no charging

    Can you copy and paste the snippet from the SM where that is stated?

    No tach,no charging

    So on the red and black wires you are seeing battery voltage only when the motor is off but then no increase in voltage when the motor is running at a fast idle?

    No tach,no charging

    Yes. Now connect the yellow input wires to the regulator with the red output wires connected to the battery and the regulator case grounded. You should see ~ 14 DC volts (meter set on DC) at a fast idle. Important that the regulator is connected to the battery. Otherwise no DC output.

    No tach,no charging

    Correct. Just connected my meter to a 120 volt AC outlet. Set on DC. A steady 0.24 DC volts were seen.

    No tach,no charging

    This is from a Mercury service manual for the OP's voltage regulator. But even if the regulator tests well, with no DC output with sufficient AC input, the regulator is faulty.

    No tach,no charging

    You are seeing battery voltage on the stator output wires with those wires not connected to the regulator?

    No tach,no charging

    It is a voltage regulator. Not just a rectifier.

    No tach,no charging

    If the motor was running at a fast idle and the two yellow wires were unloaded (not connected to the regulator) then the stator is kaput. No input to the regulator equates to no output from the regulator.

    No tach,no charging

    By serial number your model uses a voltage regulator. Which of course has a rectifier inside. Single phase AC output from the applicable coil of the stator to the regulator. On the two yellow wires. DC output from the regulator on the two red wires. Case is grounded. If the regulator fails to...

    Ethanol!

    What are the inspection officials looking for? I thought it was mainly for accuracy of volume.
