Re: Cruising Without Alternator (Temporarily)

The regulator pulsing can have different causes. Maybe it really switches on and off really quick and your meter is sensible enough to see that. This is best answered by the manufacturer. Another...

Re: Cruising Without Alternator (Temporarily)

Theway, yours is a textbook case of worn/stuck brush. In the picture with the rotor you can see the two sliprings, one shiny, one green. The brush on the green one was not touching anymore with...

Re: Cruising Without Alternator (Temporarily)

The brushes carry the current from the voltage regulator to the rotor winding via the sliprings. If the brushes are stuck or worn there is no contact between brush and slipring, and no current...

Re: Cruising Without Alternator (Temporarily)

Externally regulated but with internal rectification. Probable identification as Balmar series 9.

Theway, can you take some photos once it is out?

Re: Cruising Without Alternator (Temporarily)

Yes it could, but logic says to first supect the part that moves and wears out. Without smoke escaping one usually does not suspect the windings beforehand, but they get tested anyway when the case...

Re: Cruising Without Alternator (Temporarily)

Theway, now that we have established brush failure it's clear it needs to be taken of and opened. If you don't want to do it yourself it's fine, but be asured it's not difficult. Any local shop can...

Re: Cruising Without Alternator (Temporarily)

Generating 15kW of electricity needs about 23kW (30HP) of engine. I am not limiting anything but operating a diesel engine under 70% load is not healthy or fuel effective. A gasoline engine is...

Re: Cruising Without Alternator (Temporarily)

Your digital voltmeter is decalibrated, please refer to it's manual for recalibration. The analog one is correct, 13.2V should be full battery just of the charger (presumably solar was recently...

Re: Cruising Without Alternator (Temporarily)

It's actually pretty clear why cruising boats carry generators: the main diesel engine is to big for the installed battery size and type. This will not change until we have batteries that match our...

Re: Cruising Without Alternator (Temporarily)

Look theway, the goal is not to get 12V to the blue wire, the goal is to test the alternators internal connections (the brushes) without first dismantling the alternator. For that test to work you...

Re: Cruising Without Alternator (Temporarily)

Let's try to make it dead simple. You need: one positive wire + multimeter (or lamp) + metallic magnetic object. Take a wire long enough to reach from battery positive to the back of the alternator....

Re: Cruising Without Alternator (Temporarily)

1. Your alternator is working somewhat, you can not have 13.5V at 1400RPM and 13V at 0 RPM othervise.
2. You have corrosion on the connections and it will not get better by simply running the...

Re: Cruising Without Alternator (Temporarily)

I have to point out the obvious: alternators don't die from sitting around. If it was fine 4 months ago it's fine now. Your problem is corrosion. If you did the magnetism check correctly (ignition...
