I have acquired from my sister a 1977 Rally 200 (VSE1T) that has been sitting for 10 to 12 years. I’m new to scooters and have been slowly learning the machine and readying it for an attempted start prior to seeing whether it needs a more ambitious rebuild. It is in remarkable condition, seemingly all original and not much damage, rust or wear. I have a question about the electrical system. The model has electronic start, US sealed beam headlight and turn signals. It has a Femsatronic ignition and a Ducati 4 pole (yellow, yellow, pink, purple) regulator and wiring harness is all original. All the bulbs are 6 volt. The only visible modification is a dead 12 volt battery which I will need to replace. It doesn’t appear that the flywheel has ever been removed and based on the lack of other modifications, I don’t think the coils or the stator have been changed. I’m wondering what the12 volt battery was doing in a 6 volt system and whether I should replace it with a 6 volt or a 12 volt.
Thanks for any comments
