My ill luck with heated grips continues. The first set of Saito grips were replaced because of erratic heat. The second set os Saito grips returned because only 2/3 of the grip heated up. Then purchased a set of Dr Bike grips because J&S the supplier claim they are Oxford Hot Grips with an own brand manual dial controller. Sounds like a good combination. Wired the new DR Bike grips loosely resting on the seat and before not to long a lovely heat permeated through the rubber. Unfortunately the red LED on the controller was stone dead and with this controller it really is required to indicate whether the buggers are on or not. Controller returned to J&S who swiftly returned a replacement but sod it the LED is again dead. Patiently the second controller is now in the post and if the 3rd is knackered the lot is returned for a refund. Pity because the grips do reach a toasty temperature. Will keep posted.
