| Has your bike got the interlock with the sidestand and neutral light?
If so, that could be part of the problem as that system looks to see if the bike is in neutral and the faint glow suggests a partial short circuit to earth somewhere in that circuit.
I have also known problems with glowing warning lights to be associated with rectifier problems which when this occurred on my ST2 made the engine falter when revved hard. |
