I'm looking at adding a resistor or bulb inside an Acorn stair lift motor housing to keep the temperature about 40degF. The unit is in an unheated area and temps get too low for the motor to turn normally. I considered an electric blanket or pad but having an elderly person messing with something on the stairs is not a good idea. Also, there's the issue of having a separate part and cord to deal with.

Cheat this out and see what you think. I have done this when setting up electronic devices in remote locations, installed in an insulated box with a car battery & resistor. In this case a night light bulb might be another choice.

you should ask in sci.electronics.repair and maybe
sci.electronics.misc

Thanks, I did post at the repair group and got a few good replies there. Not like here though. This group is the best starting point for just about anything including computer issues. There are dozen or so regulars who have done just about everything around the house, always helping the beginner folks.
