[QUOTE="helotaxi, post: 4066371, member: 550915"] Your stock electrical accessories draw a lot more than 30A. The headlights will draw about that on their own. AC and ABS computer are a big draw also. Then factor in the ECU, fuel pump and ignition module. Don't forget the instrumentation and other misc stuff. The vehilce probably uses close to 80A when a lot of stuff is on. Chrysler didn't provide a 130A alt because they thought you would want to power a stereo, they installed it because the vehicle needed it. There's a bit of headroom factored in for duty cycle and aftermarket accessories but not 100A. Does that mean that you'll have a problem? Probably not but don't think that you've got anywhere near 100A of excess current to play with. [/QUOTE]
