    Ok really need some help unless i can figure this out in next hour before i call it a day. It seems i've got bigger problem than idiot light. Came into shop this anoon and had less than 1 volt on battery. Put battery charger on it for 5 minutes and charger showed full charge. Disconnect my jumper wire from term 2 and instantly battery showed correct voltage. Without idiot light hooked up, tried running main battery wire from alternator and term 2 wire to fuse block on the 'Batt' fuse like diagram suggest. Put multi meter on there and literally saw the volts drain away fast..... This does not seem like rocket science. On my old push button toggle system i had the alternator main wire to the battery and term 2 wire to a toggle switch that controlled my coil and had no problems.. Any ideas lol?

    Edit: I rewired the alternator as a one wire deal and did not hook up/touch terminal 2. Did hook up idiot light and with car running the light did not come on. Still going to monitor and tinker with tmrow anoon as i'd like to get term 2 straightened out. What i don't get is that my multimeter showed 11.5 volts at battery, when motor was running and also off but the volt guage only showed 9.5 when running...Also, i don't see as how i have a parasitic draw problem either since that's on my mind considering i had no juice today. I've only got a 5 fuse block and the only term that stays hot all time is the one battery fuse (battery lead feeds this fuse and another wire to 'batt' term on switch), i dont have anything running on other end of fuse. Perhaps will draw a sketch of my simple wiring diagram.
