Cummins Support Tech

Personalized Tech Support

Knowing which part you need isn’t always as easy as you might expect. That’s why Ward Leonard provides Authorized Tech Support to help you define exactly what you need to get your alternator back up and running. Much more than a distributor, we’re an Authorized Service & Repair Center that has handled hundreds of alternator projects over the years — and there isn’t a part we don’t know, can’t find, or can’t repair. Call 1-800-673-0531 to discuss your specific part — or any other maintenance and repair — needs.
