Has anyone else had problems the the MV50 (also called the M1050 I think) air compressor blowing fuses? I've heard of people running them on continuous duty for upwards of 30 mins, but I went through 2 fuses in less than 15 mins last weekend. Both blew after stopping the compressor to switch tires then trying to turn it back on. Is mine just defective? It's only been used to air up 4 tires 4 times .
