[QUOTE="Jeffdachef, post: 8630646, member: 650438"] a cold start is when you first fire up the car. After the alt gets hotter, the output starts dropping a bit due to heat and efficiency loss. Thats what i meant with a cold start. A cold start does not mean the car is off, otherwise there would be no "start" in a "cold start" So basically your voltages is pretty constant between cold and hot My car is 14.1 - 14.2 max at a cold start, never saw above that until Singer made me a pigtail connector that got me up to 14.6-14.8. However my car's ECU fks me over. after 2 mins of driving at anytime i'm under 750 rpm, my alt doesnt even charge. at 1k rpm i get 14.4 - 14.5 and 1.5k rpm i maintain 14.8. Its not the alt or anything else, its just how my vehicle computer is programed to save gas. Literally need to find a guy that can do some ECU tuning. Does the same sh*t with my stock alt too.
