Re: (ET) field weakening potentiometer with a Curtis 1204



I designed a circuit for the 1204 about 15 years ago but ended up installing an alltrax.  I don't think the list will accept attachments, but the pdf should make it through to your personal email.

I am considering putting a Curtis 1204 (sitting on the shelf collecting
dust) in an E15 (most of card 1 has been bypassed by the PO due to
failures).

I vaguely remember reading somewhere about a user putting a
potentiometer in the field to provide a variable "turbo mode."
The resistors on card 3 are 20 ohm 10%, but what wattage are they?
IE what watt rating would the potentiometer need?
