Just picked up a Kriss Vector for $30 due to the motor giving out a puff of smoke on firing.
Fire select works fine, so no mosfet issues. Looking at it while it’s apart and test firing it with a 7.4v battery I get a tiny puff of smoke out of the back of the motor just behind where the red active wire’s soldered onto the motor, that’s if the red and blue wires are what they’re supposed to be.
Is it the motor itself that I should be replacing or looking further along the loom for problems? Everything seems okay on visual, but I wouldn’t want to melt this thing… or fry the mosfet.
