I'm having a wee bit of a problem with my S/D Controller,When i turn my key to get the ignition switch, i get a solid red light, Mobo switches on, and all is good, but now, when i switch off, the mobo cuts off . the light on the SDC flashes about twice every second. At this point, everything is good, BUT!

when i turn the key at this stage, it still flashes twice every second and the mobo doesnt switch on, i have to like pull out the ground and reconnect, then we start all over again. Do tell me what could be causing this. could it be grounding? as the psu, mobo and sdc are all hooked up to chassis of the ampie case as ground and direct to battery -ve as currently it's on a test in my room before i hook it up in the car.
