So my bike is near ready to go aside from this issue with the brake lights.
I have studied the schematics and traced what I could and here is what I have gleaned. The lights for the brakes seem to come directly from the coil. The coil also supplies power to a front cluster through a second wire. There is only one wire currently ran from the coil so my assumption is that wire is missing and has been removed.
The brake switches, seem to work as a ground. They are open circutes and braking turns the ground system on. The housing that's installed on the bike, seems to be a dual element system from a Suzuki ts150.... No joke. Someone didn't do their homework when replacing parts. Long and short, the housing has a shared ground for both brake lights and the tail light. And this is making it so the brake lights literally can't work with this setup. They will be always on no matter what with this bulb setup.
My question has multiple parts. Does my reasoning seem sound with the information provided from the schematics? If not, could I have a second opinion from someone better with electrical then I am?
Lastly, if I am correct. I need a housing that should have 2 bulbs. I cannot seem to find one anywhere. Not ebay or anything. Does anyone have any knowledge, info or whatevers that might point me in a direction of finding one?
Thank you all for any help and info in advance.
