More basic question about sevcon gen4

Ryan Sweet All Messages By This Member #30658 开云体育 ?Does one expect the sevcon gen 4 to clear fault codes without intervention if the fault condition is ameliorated, or is intervention required? With my old Toyota Highlander hybrid it always required intervention if a fault code was triggered. You had to send a reset command via ODBD-2. ?? I am assuming the sevcon is similar. ?I have put everything back the way it was when it was working, and voltage at the throttle (potentiometer - I have the Curtis throttle from the thunderstruck kit) - checks out normal. ?The throttle is in the off position. I don’t know how I would check the output current, without the throttle telling the motor to go, but I’m wanting to believe the fault had something to do with the charger being applied to the circuit as that was what changed. ? If the expectation is that the sevcon gen4 ?will return to normal once the fault condition is no longer true, then my working assumption would have to shift to either the throttle or the contactor being damaged in some way.? It was a bummer because I methodically tracked down and fixed all the vibration and alignment issues until it was humming as silently as could be expected, and was just setting up to wait for the tide to put it back in the water.?I suppose it’s good to be learning about these things before I am somewhere far from home.? This is the section of the manual with fault code 6 (formatting is wonky but it’s (fault\|causes\|procedure)... — 6 Throttle pressed at power up DI Throttle demand is greater than 20% at power up. Reduce demand 6 Analog input wire-off VS Analog input voltage is outside allowable range. Check analog input wiring Monitoring Doc. #?177/52701 Rev. 3 7-7 LED flashes Fault Level Set conditions Operator action 6 Analog output fault (over/under current, failsafe, short circuit driver) VS Analog output fault caused by over current (>4A), under current if actual current < 50% target (current mode only), failsafe circuit fault, short circuit driver MOSFET. Check analog output wiring.
