Heated Grip Update
Doing the sums tells why. The grips are about 8 ohms each, so are 18 w at 12 v so 36w total. When in series, its 16 ohms total for 9 watts total, so 1/4 the power for the series connection compared to the parallel. OK for a low setting, just, but something in between like the resistor solution would be nice too.
I could revert back to the original resistor solution, or install a flasher relay for a similar 18w total outcome.
On my 1400GTR I have some Oxford grips with a variable output controller which work well and gives me more options for heat settings. I thought it'd be nice to have something similar on the DR, its winter here now! I didn't want to lose the ability to use any dirt bike grips I like, so wanted to keep the existing heaters.
I tried to track down a variable controller and came up with some options, ending up with Tusk kit from eBay for $54 delivered. 10 days from the US. Just a controller only was more expensive. The kit is nominally for a snowmobile or ATV, so both grips are the same size inside, but didn't want them anyway, so cut them off and used the controller and harness attached to my original grips. 5 heat settings now.
The kit spread out.
The controller mounted up next to the headlight switch.
