So my battery has been discharging (yes, I read the tracing a drain sticky). Yesterday I had a little time to play with the multimeter and got the following readings: 12.35V with ignition off 14.55V idling 14.7-14.9V under throttle 13.9V idling under load (headlights only) 26.9 AC idling 12.9 when ignition turned off, dropped down to 12.56 At 10pm I disconnected the alternator because I thought a diode might be bad reading 12.4V Next morning @ 930am (11.5 hours later) battery was down to 12.26V Reconnected the alt and checked the draw (193ma-194ma). Checked the fuses and the tail lamp circuit dropped to 13ma when I pulled the fuse. I don't know much about electronics and I find wiring diagrams confusing. So my question is what all runs off that circuit and can I trace it down without tearing apart my interior?
