As I installing my first decoder could I ask a question please.
The decoder is sealed in clear plastic.
I assume take this off so the heat dissapates!

Leaving the plastic on would be nice as it would be easy to
stick the plastic to the loco body rather than fixing
the decoder.

Hi
You havent stated what make of decoder your using??
If the "Plastic sleeving" which I suspect is heat shrink tubing factory fitted, should be left on. Digitrax are often sealed. Some decoders are supplied like this and other makes either have a piece of tubing supplied but not fitted (Hornby for example) while others have none at all and it isnt needed for these.
Hope this helps

You have not said which type of decoder it is but I would not remove the plastic sleeve as this is for insulation and make the location to place the chip easier. If you remove it you may find that if it moves it may short out on part of the loco chasis and thats one dead decoder. Some of the chips that come with a sticky pad to attach one side still need the surrounding metal parts insulating to stop the chip touching any metal parts whilst assembling the model. I have found that most chips do not get very hot unless you overload them, normal running barly gets them warm.

hope this answers your question

drive is the same as this.......
