chrisexall Posted August 30 Report Share Posted August 30 My controller seems to be jammed on the reset function. I've renewed the switch which hasn't cured it. Any ideas what to do next? Quote Link to comment Share on other sites More sharing options...
konrad Posted August 30 Report Share Posted August 30 You need to explain the problem in more detail. Do you have the optional regen lever (EM calls it PRB-R)? Are any tones emitted by the motor when you press the map button? Note that the controller will not permit the motor to run if there is a fault with the throttle. You can find the wiring diagram here: https://www.electricmotiontech.com/home/em-epure-race/wiring-diagram Quote Link to comment Share on other sites More sharing options...
chrisexall Posted August 30 Author Report Share Posted August 30 Hi Konrad No Regen lever. Every time it's switched on it goes through the map reset process inc sound. It has new map button. Quote Link to comment Share on other sites More sharing options...

konrad Posted August 30 Report Share Posted August 30 It's easy to try the encoder re-calibration process described here: https://www.electricmotiontech.com/home/em-epure-race/motor#h.aqwdzouw61q4 It's possible the throttle signal is out of range. You can try unplugging the throttle, cycling the battery on/off and then reconnecting the throttle. A crash can also pull on the handlebar wiring and cause trouble. It's best to have some slack in the wiring to the handlebars. Check for poor contact at all the connectors. Failing that, it will take someone with electronics knowledge and a multimeter.

chrisexall Posted September 4 Author Report Share Posted September 4 I've renewed the wiring loom and it worked for a bit then went back to being faulty. The only other bad bit of wiring was the battery display lead, especially the earth connection. I've removed it and at the moment it's working! Could this be a coincidence or could a bad earth cause this malfunction? Quote Link to comment Share on other sites More sharing options...

Could this be a coincidence or could a bad earth cause this malfunction? It definitely sounds like a bad connection somewhere. I'd suggest going through every connector, visual inspection, contact cleaner, then dielectric grease (around the plug, not on the metal bits) and a double check that the connector is back together properly afterwards.
