Hello,
An ETZ125: my rear stop light comes on (faded) when ignition is turned on. The red/black wire from it to fuse box 3rd right is the same terminal as the coil, also flasher unit.
Any ideas what is causing this, is the coil doing something to it?
I have a spare thick black mudguard wiring loom and I temporarily replaced this and the brake light still comes on faded. It shouldn't come on at all.
Thanks for any advice.
