Frequently asked questions
What should I check when ordering a replacement alternator for the Triumph Bonneville T100?
Match the exact engine code and the model year of your Bonneville T100 T100, 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.
