How to replace the Fiat 500's dynamo/alternator

Model: Fiat 500 Epoca - Years 1957-1975
Part: Alternator

The instructions provided in this guide will show us the process of disassembling and replacing the dynamo/alternator of the Fiat 500. First, we open the rear engine hood and start by removing the air filter box and the fuel pump membrane; then we disconnect the dynamo belt and unscrew its screws to remove it along with its pulley, as shown in the video. At this point, we replace and install the new alternator, checking its actual operation with a multimeter; we then reassemble the previously disassembled components.
