I just installed a hartco seat and I knew I would lose the heated seat but now the grips are not working either. am wondering if unplugging the seat caused this problem and if anybody has a suggestion on how to fix it. Thank-you for any advise.
Fred is correct in that the heated grips will not work with the seat thermistors disconnected from the heat controler. I fabricated a plug with 4 - 166K resistors replacing the thermistors in the circuit for a friend and this enabled the heated grips to work with a non-heated Ultimate seat. He's been using it for about a year now with no problems.
I have read that Lewis Preston of The Electrical Connection may be working on a fix for this problem.
