So my 36V Ultrex just left the shop again this afternoon and it appears the main wires to the motor (located within the tube) melted together and shorted out. What the hell would have caused this on a 1 year old unit? They shorted one and other about 6" up from where they connect to the motor or lower unit itself. Burning completely through the hot wire. Also why didn't it trip my circuit breaker at the battery? Crazy what I've gone through with this TM in the short time I've owned it.
