Bought the CA3 DPS about 9 months ago along with a Thun and mounted it on a Recumbent Trike to measure rider power and a lighted gauge. Worked great. Thats on my wife's trike.
Also have one on mine, along with a Phaserunner and MAC 10T.
Just finished installing a Phaserunner and MAC12T on my wife's trike. Speedo works fine unless the motor is running. Once the motor pulls over 10-15 watts there appears to be an inductive input to the speedo. The speedo is connected to the front wheel but setting the rear on a jackstand and running full throttle it shows 65 MPH.
I disconnect the speedo wire (previously added a JST connector) and route the wire away from all others, it still tracks motor switching speed.
If it were radiated susceptibility it would likely be an H Field (magnetic) rather than and E Field (inductive) if it was due to the Speedo wire. Its worth mentioning that the Phaserunner is about 6" from the CA3 on both trikes. Only having a problem on one of them.
Its also possible the 6 pin CA3 -Phaserunner cable is inductively coupling as it runs along the back of the Phaserunner. Depends on the sensitivity of the speedo pickup I suppose.
Anyone have some insight?
