Carrera 26732 in Revoslot, having problems

[DRW-FJ40]

Hi. First post here, discovered this forum a few days ago. Recognize some people from SCI... anyway....

I just installed a standard 26732 in a Revoslot. It seemed ok but going backwards so I reversed the motor wires & now the motor is pulsing quickly, the car moves in quick little jerks or pulses. It could have been doing that before I switched the motor wires. It only ran for a split second before I took it off & reversed the motor wires.

Any ideas on what might be wrong? No lights so it was a pretty straight forward install.

Well I believe I figured it out. I didn't insulate the chip from the aluminum chassis. I saw another thread where people were using a 3D printed insulator. A bit of electrical tape did the trick but the standard Carrera chip hits the little brass nuts right in front of the hole for the LED light so I may fashion something out of styrene.

I only have one chip in a metal chassis but all I did was a dab of hot glue on the corners to insulate it off the chassis.

Blue Tack works really well too.

Thanks, I ended up using double sided foam servo tape, seemed to do the trick also.
