Hello. Is this possible? Mine is 2002 model but with tuned engine and no battery. Ok to connect them up to regulator rectifier? Also will lack of battery mean I can’t fit SIP digital speedo? Thanks...
The SIP Speedo comes with a little black box which is a regulator-rectifier. So no need for a battery.
-> Your stator plate only has a limited electrical power output. You need to attach a powerful battery to run your Vespa with heated grips. Othewise the electrical circuit will break down in cas you need all consumers.
