I get this response with both my PS2 and my one PS3 engines. If I switch on the power with the MRC Pure Power Dual rocker with the handle on full they catch the WD. If I use a toggle on the siding they are on they start up. I just hit the startup button and all is normal. However, if I don't hit startup soon enough on the PS3, it takes off and I have to cut power and start over. Everything else is fine when I get them out of that funk. Usually the problem only shows up when I use the toggle switch.
