dcc decoder tester
« on: August 12, 2017, 09:29:16 pm »
hey,

does anyone have a decoder tester?   

i have 4 or 5 decoders that i have removed over the years, can't remember why now though (3x old bachmann blue ones, 1x gm, 1x other).   i am either going to re-use them or sell them if they work ok, or bin them if they don't...

if anyone would mind me posting them to you to test that would be much appreciated.  you can keep one of the decoders as a reward for helping out!   i don't really want to test them in a loco in case they damage it.


cheers,


tim

How would a decoder damage a loco? Do it on the programme track to be sure. It'll be fine.

If they are plug-in types then, as Njee20 suggests, just pop into a working loco, with lights, and read some CVs.
If that looks ok then pop onto the track and check motor operation and light functions are ok.  Remove and sell as checked and working.
Repeat with each decoder.
A loco is much more likley to damage a decoder than a decoder a loco.

For wired decoders then an interface or decoder tester is usually required.  A decoder tester is really easy to build, just some terminals, 6 pin plug, up to 6 LEDs, same number of 1k resistors, and a big resistor (say  200ohm/ 2W) to act as a motor (assuming you don't use an actual motor), piece of vero board.

Or, if you are ok financially, then an ESU tester is a good purchase and very comprehensive.
