    Blowing the fuses

    Hi, I just finished up building my 3 axis board and started testing it, however i blow the 3 amp fuse all the time. The first time I turn the sysytem on it works, but when i turn it on a second time the fuse blows instantaneously, i checked everything and can't seem to find a problem. Is the system suposed to be grounded somewhere? Any help greatly appreciated

    Thanks

    I was having the same problem (my kit is no longer in use). What I found, is that if you toggle both switches at almost the same time, this will happen. When powering up, turn the fan switch on. Wait a few seconds, then turn the main switch on. When powering down, turn the main switch off. Wait a minute or so, then turn the fan switch off.
