Breaks defective

[Jonny...G]

Sorry...."Brakes"..........Hi. When I switch my engine on it tells me to visit workshop and malfunction electrical consumers switched off. Then when I drive it keeps bleeping at me telling me to stop and that my battery/alternator not working therefore breaks are defective??? The car still drives perfectly tho. Iv checked and both batterys and there charging at 14.6 v so I think the alternator works fine. I've also replaced the small battery in the front.... Also Iv checked that the cut off relay and that's fine. Iv also replaced the battery control module. The only thing I have not changed is the big battery in the boot but the engine starts fine so I didn't think there was a problem. Both battery's sit at 12.6 v too witch I believe is good?????? Please help me some1 as I'm out of idears. Thanks Jon

Iv done that and the only fault it came up with is the cut off relay but Iv checked that and it's working fine
