Are there different wiring currents behind the headlight? The manual shows that the side lights and lights have the same voltage (12V) and power (15W) ratings. I'm wondering if someone can verify this.

My heated grips seem not to heat up to the same temperature as they did before. I can't remember which wires they were attached to previously. The heated grips do get warm. Just not warm enough. I'm wondering if anyone has any advice regarding which wires to wire the heated grips so that they'll be lovely and toasty. Of course, I have the temperature turned to the max.

Thanks 😊

All battery circuits are the same voltage, 12V. It is always best to run a separate wire (of the correct guage) directly from the battery for accessories like heated grips, and that wire should have it's own fuse located close to the battery. Connecting heated grips to a lighting circuit risks overloading the lighting fuse. Also voltage to the grips will be less due to voltage drop caused by the lighting load.
