Replacing the alternator

After 23 years of operation, it seemed that an existing alternator was not charging or was not charging the consumable batteries sufficiently, which were not charged even after more than 8 hours of sailing on the engine. Therefore, I decided to replace the alternator with a factory new part. It works like magic!

Going well so far -)

I installed this alternator in a YSM12. I just had to re-crimp a connector.

Delivery lightning fast!!!

During our vacation on the Göta Canal, the alternator broke! I ordered a new one over the phone literally at the last lock, and after 24 hours the order was delivered to a small town in Sweden. I am very impressed with the service, even a query about an incorrect delivery date in the UPS shipment tracking was handled and resolved in a very friendly manner! Thumbs up for the service from SVB, it couldn't have gone better. Thank you! The alternator has been replaced and the battery is charging!

Identical alternator

The alternator really does seem to be identical to the one originally installed by Volvo Penta, but at a much lower price. The alternator came with the usual report of the individual final test before packaging - that's all Volvo supplies. Even the impeller for the V-belt fit for me. If it doesn't fit, as I've had with other Volvo Penta replacement alternators before, just take the new and old alternators to the nearest garage and ask them to use a pneumatic impact wrench to transfer the old V-belt pulley from the old alternator to the new one. The old impeller can be reused without any problem, as these alternators, unlike cars, don't have a freewheel that wears out. The conversion with the impact wrench in the garage actually takes a maximum of one minute.
