Alright Alternator installed on a 2GM no problem I recommend

Order processed in a very short time. Perfect product. The alternator works perfectly.

by paolo M.

Great value for money As always, the alternator was delivered quickly and works perfectly after installation. Since it has more power and is therefore larger, it just fits with the installation, but still without any changes (standard LiMa 35A on the Yanmar 2GM).

by Ingo B.

Very good value for money due to the good fit completely problem-free installation and perfect function

by Kai R.

Alternator for 2GM20 With the old alternator, the charge indicator light never went out completely, it kept glowing. The new one is working flawlessly so far. Remarkably, the mounting holes in the original alternator are also too large (10mm for an 8mm bolt).

Technical question

Karlis B. | Aug 15, 2025

Can I add to this alternator external regulator? Wich do you recomend?

Answer from SVB customer service

M. B. | Aug 18, 2025

Hello Karlis, advanced alternator regulators (e.g. #17335#) raise the alternator’s output voltage. On older boats and vehicles this is usually not an issue, but on engines with an ECU it can trigger alarms. For modern engines and vehicles, it’s better to use a Sterling Alternator-to-Battery or Battery-to-Battery charger, as these provide the same performance benefits without interfering with the primary system or ECU. Best regards SVB-Team Bremen
