Hi, we are working on a Raymond Model: EASI R40TT s/n: DZD03-27475. 6G is overheat for the motor. We have replace the sensor and we still have the same issue. We suspect the vfc but we are wondering something... When the sensor is unplugged, we have the 5 volt at the vfc pin all the time. When we plug it, it varies.6 volt to 1.2 volt. The question is: Is it the vfc itself that drives the 5 volt or is it the other computer below who does it for him? thanks in advance for your help!
