Need some help with my CA coupe PLEASE

[TeamGreen]

I recently installed a CA MAF that I ordered from Japan... And Aftermarket pulleys onto my CA18det .... The alternator was kinda going but still working okay .... While test driving it drover super cherry for about 10 minutes ... After a while I noticed the dash clock was off and the rpm gauge starting going all crazy .... I pulled over and it seemed to stop so i kept driving ... About a minute later the gauge went crazy again ... The electrical started trippn out ... The motor started sputtering .... An old alarm starting going off (I've had the car for 3 years and never heard any alarm).... Then everything died and the bumper lights and taillights are stuck on (even with no key) ... And nothing goes on...no dash lights ,radio, dome light, gauges... Doesn't start at all.. Please help if you got any ideas
Thanks

I think you answered your own problem, alternator.

I had it rebuilt the next day... The bumper lights and taillights are still stuck on...

I had a similar problem with my alternator, but it was more with the dashlights staying on. Sometimes the relays may get stuck open/closed which may cause some issues like these. Just remove them, gently tap them, and replace. Try taking the car on a long drive after this to fully charge the system. This fixed my problem.

Okay I'll try.... How do I get to the second accessory relay??

go under your dash and check the fuse box there iirc. trace it back and look for where the alarm splices into the harness from ignition.bust out the handy dandy volt meter and reads the ohms on there and if it is kicking on and off or anything at all.

Sounds to me like a short or the harness itself...thats a huge tripping of the car but then again I might be wrong. +1 on te alternator...cheapest and easiest fix. Start with that one and work your way up. Might be just a little stupid short.

Good luck dood.
