When your Thermo King refrigeration unit starts acting up electrically — battery draining overnight, fault codes on the controller, unit cutting out mid-route — the alternator is almost always where the problem starts. This is especially true in Canada, where a failed reefer in January can mean a full load of spoiled product.

The 45-2776 is a direct-replacement alternator for Thermo King SB Series and Spectrum refrigeration units. It runs at 14 volts and 65 amps, exactly matching the original specification. It mounts where the old one came off, connects the same way, and does the same job.
