I installed the kit about a week ago and followed all directions as it said (Used tutorial on this forum). And it only worked for the first night, every time I turn on the system I always get the 3 Red lights again. What should I do.
Depends where you're located. $50-$60 usually in the States, not sure what pricing is in the UK but I'm sure checking Martin C's or BGAMods' threads in the service section will give you an idea for across the pond.
