I lost the rubber insulator that goes around my starter solenoid/relay/switch a long time ago. I move all my electronics and used two P-Clamps to hold the solenoid away from the frame. But there is a potential ground path from the body of the solenoid to the frame. Is this a problem? The rubber insulator made me think maybe the body of the solenoid had to be isolated from the frame/ground, but maybe it's just there to protect from vibration. Anyone know?
