Hello, I recently bought 2 of these PWMs here, http://www.ebay.com/itm/10A-Pulse-W...697?pt=LH_DefaultDomain_0&hash=item48542d0c31. I planned on using them in a conjunction to control the power going to a small vehicle. At first they appeared to work, but now both seemed to have developed issues. The range of the PWMs has gone from 10%-100% to more like 95%-100%, which is pretty useless for my application. I originally wanted to get a higher current rated PWM, but these were the only ones that shipped in a reasonable about of time. While in their short time of use, I blew their fuses several times, though I never bypassed the fuse with one of a higher rating. I'm very frustrated at this point and have no idea what to do or what is even the problem. This is for a high school project and I would greatly appreciate any insight I could get.
