Lines: 9 I'd say an 18-20V trigger would be better - do you know how high the voltage goes when your running the alternator? Usually around 15V. Most ICs that I've seen for automotives (that want to hang right on the battery) are rated to around 28V. Kristi Bittner hplabs!hpscdd!kristi Brought to you by Super Global Mega Corp .com
