Slide Controller Damaged

I was working on re-attaching my sofa arm and bumped the cable harness to the slide controller. The power input was loose, popped off and touched the adjacent motor lead. The slide will not move now, but I hear the relays clicking. I removed the controller, opened it up, and there is a current sense resistor (R6) between the motor power and ground which is burned up. I got a partial part number from it, Ohmite FF010, but a search online turns up nothing pertinent.

Has anyone made a similar repair, or does anyone know the value and wattage of that resistor?

Thanks,

Al

Al, you will need the ohm rating of the resistor. You might be able to remove it, and take it to an electronics shop to see if they can identify it for you.

Thanks Terry,

I think I have determined what I need. I could read "Ohmite FF010" on the burned up resistor. That part number doesn't turn up, but when I looked for Ohmite shunts, I got some references for newer part numbers. It looks like Ohmite's part numbers have the resistance in the numbers - 010 is 0.01 ohms. Looking at the power gear service manual, my motor probably takes about 15 amps. So the resistor needs to be rated at 2.25 watts or more. I can get a 0.01 ohm 4 watt resistor for $1.77 from Digikey. It beats $125 for a new controller.

I think I'm on the way to a repair.

I McGivered it by putting a piece of wire in place of the resistor and the slide still didn't work. I found a broken spade lug on one of the motor wires. That may have been the real problem; the resistor may have been damaged but still working and my jostling the harness was the last straw for the spade lug.
