Adding Choke to controller

Hi, to continue if you solder remaining wire's to their respective contact's but starting from last diode to first the preceding soldered wire hold's thing's in place I went back to check the switch's iv'e wired up this way for a project some year's ago, useing the 3amps must admit there a very tight fit but if you put the wire's in a vice and squeeze them they then go thru quite easily but your useing 6amps and presume the whole diode is of a larger size then you would need to solder to the outside of the contact if you bend the loop back on it's self to provide a flat surface then after tinning the loop and wire well and holding the wire with plier's the wire can transfer heat very quickly then soldering should be ok. To connect the switch to the main wireing solder the positive wire from the transformer if your track's positive wired to the first contact number 1 then a wire soldered to the centre/ wiper contact and back to your controller or controller socket, after all the above and still want to use the switch's but think it will look a bit messy you can attach diode's to a terminal block on one side with wire's from the other side and then soldered to the switch or simpler yet just use the terminal block with diode's in a chain attach transformer wire as above to first wire first diode then attach crock clip on return wire and just clip on desired diode for adjustable brake's the set-up's the same but connect brake wire from controller to contact 1 then wire from centre/wiper contact to controller plug/track useing suitable schottky r/diodes IN5817 are ok for up to Boxer/NSR motor's which ever way used contain it all in a box for safety, sorry it's been a bit long winded hope it help's phil.

Eleven years is a long time to wait for an answer to your question. It looks like somebody hijacked part of one of my schematics. Here is a choke box with diodes that will drop 4 volts.



Since this thread started controllers have become more sophisticated. Electronic controllers have an adjustment included in the control circuit so the power to the car does not have to go through the pot itself. If you choke back on a car its top speed will probably be reduced, many controllers with chokes bypass the choke when the trigger is pulled all the way. With a controller that I use for ho cars that bypass can be turned on or off.
