The last time I was out riding coming home in the dark I noticed that if I turned my hand warmer and thumb warmer both on HI my lights would dim. Got home checking it over I find my fuel pressure is at 38 with warmers off then when I turn both warmers on my fuel pressure drops to less than 30. I have never noticed this before and I am wondering if I have a short or where I should start looking. Anyone saw this before?
