i stuffed an 85 turbo diesel motor into an 82 yota 4x4 and will be using the mercedes alternator. There are 3 wires coming out the back, 2 thicker white/red charging wires and a thinner white/blue. I intend to run the charging wires to the battery+/starter connection. Wondering what the white/blue is for? I've read it is a "charging indicator" but does that mean that it is always lit on your display? If i were to splice it with the indicator lamp wire for the cluster in my yota would this mean the battery light would always be "on" while driving, and then only go off if the alternator failed to charge?
