The solenoid installed before was functioning intermittently. I had to knock to make it work sometimes. No wonder it was free from a shop. So I bought replacement solenoid from auto parts store for $13. Installed it without bench testing it, thinking it is new. What could be wrong? Right?
Well, it didn't work. The coil is open, no continuity between the two small posts. I could returned it for another unit but I decided to have fun. Drilled out the rivets to open up the solenoid and found a problem. Soldered a wire to complete the coil. Re-assembled all back and it is working as it should on the bench. Installed it onto the scoot and still working.
Found some Vino 125 front end parts on eBay to entertain my idea of having disc brake on my Riva. But I think I have to let them go for now that I cannot afford them.
