So im having an issue when i press the brakes the dash lights up, clock dies and the car just dies, like all the power is getting sucked out of the battery! I think it might be a grounding issues but not sure... If i could PLEASE get some ideas on where to start looking that would be GREAT!!!

BTW all fuses are good!

 

i would start looking around the brake peddle? loose connectors at the fuse box maybe?

 

if you had any wire tuck done or you did them your self I would re-check those. I thik it's definitely a ground or a live wire that;s touching something

 

Does someone know the locations of the grounds for a 91 civic si hatch???

 

Bump!

 

Start looking here. There is a brake switch at the pedal to turn on your brake lights. If there is a bad connection or a short to a ground here that could cause those symptoms.

 

try getting your battery load tested also -- check your battery ground
