Kid-Ae Posted June 6, 2011 Report Posted June 6, 2011 My problem: - Charge light stays on, kills battery. Solution? Changer alternator! Dilemma - Nippon-Denso unit has a plug on the side (guessing this is neg, earth, fuel). Bosch unit found at wreckers is an internally regulated alternator with a completely different setup. Is there a way to install the Bosch one? Just want to get this sorted before I tackle the rest of the electrical system (kind of helps to have a battery that will hold charge). Thanks. Quote
ke70dave Posted June 6, 2011 Report Posted June 6, 2011 (edited) alternatively.... take alternator back to wreckers get money back. take original alternator to auto electrician, get him to test it. and/or get him to fix it. then no stuffing around with regulators. did you check your voltage with running engine to make sure that the alternator wasn't charging? also, "neg, earth, fuel"....what is fuel?

Twinky Posted June 6, 2011 Report Posted June 6, 2011 Charge light would be staying on because the battery voltage is too low, probably just worn out brushes. Go to an auto elec and buy them for $10 and replace them. But before doing that make sure that the alternator is not charging the battery. Anything below 14 volts is low charge. Quote

Never bought it, it was already out of the 4k when I was there and decided not to buy it so I wouldn't f@$k up. Yeah, it's been tested and was struggling to put out 12v. (started the car with a 580cca battery, only one I have that would get it going as the alty has killed the other two) Fuel is for fuel solenoid?

ke70dave Posted June 6, 2011 Report Posted June 6, 2011 not sure on the fuel thing, maybe.. some info here might be helpful: http://www.rollaclub.com/faq/index.php?title=Tech:Engine/K_Series/Alternator Quote
Kid-Ae Posted June 6, 2011 Author Report Posted June 6, 2011 (edited) So from doing some reading, my understanding is that I, in theory, COULD replace the external reg with the internal reg. The internal reg grounds itself and then the alternator only requires a the usual battery wire and charge wire to be placed on the back via ring terminal/blade terminal on the B+ and D+ terminals. This also means I can remove the messy wiring from the external reg and clean the engine bay a little. Am I even close? Not sure on electrical systems but I'm willing to learn the slow, hard way. Thanks :) (sorry if I sound like an idiot, I just want a better understanding of how it all works). Edited June 6, 2011 by ROLLA'BOY Quote
