Post Subject: weird alternator problem..hello! I recently had my alternator reconditioned as it wasnt charging well. Got it back and still now charging well! only at maybe 13v with new batteries! 2 strange things happened: 1 is that if i start the engine on 1 (on my 1/2/both ) which is my starter battery, it charges at 14v and i can lower the revs and it stays at 14v...but when i switch it then over to both, the engine lowers its revs and the voltage on goes down to maybe 13ish!?? Another weird thing is that on the back of my alternator I have a small rubber black box connected to the alternator, I looked this up and apparently it doesnt do much. But If i unplug it i get better voltage and if its plugged in!? Im really confussed! all the wiring is the same as when the alternator worked before it broke. I have recently added a nasa battery monitor, I also have a adverc hooked up. any help at all would be great! WHAT IS THIS WITCHCRAFT...
