Ground Kit Problem

[JDMark]

so i bought a full ground kit from a friend for 20 bucks,its a high quality one with gold plated ends and whatnot (says hks on it but its red, and i think hks only makes purple ones) anyway i got it on and everything was great, car idled smoother, stereo sounded better, etc. we hooked it up to the intake mani, head, block, tranny, and 2 spots on the chassis.

after i test drove it, it wouldnt start back up (after about 20 mins of sitting) wouldnt even turn over, it was like the battery was dead. wtf? so i took it off and just slapped on the old ground wire to the intake mani and it fired right up. fuckin confused... did the same thing on my friends, but he thought it was cuz it was hitting his hood. we both have the same alarms... could this be it? any insight would help, thanks!
