About this part

The alternator on your Signum charges the battery and powers the electrics while the engine runs. A failing alternator causes dimming lights, a dying battery and eventually a vehicle that won't start.

Frequently asked questions

What should I check when ordering a replacement alternator for the Opel Signum?

Match the exact engine code and the model year of your Signum, as alternators differ in output (amps) and mounting. Check whether the pulley is included or needs to be transferred.

Is a remanufactured alternator a good option?

Yes – remanufactured alternators are tested to OEM specs and are often significantly cheaper than new. They're a reliable and economical choice for most vehicles.
