Just installed a new CS alternator on my 2.8 and It wont charge the battery. This is a continuation of a battery charging problem that Ive been fighting since I had my stock alternator. The L wire is only hot with key on and S wire is hot all the time like it should be. The other wire is connected at the stud like its supposed to be. Battery is low to start since It hasn't been 100% charged since I bought it last month since the it keeps dieing from not being charged. Is there a fusible link or something that may be fried? If so, what do I look for? Im open to all suggestions.
Returned my 2.8 back to stock for the weekend (Took of the supercharger) and the car ran fine and the alternator charged the battery and it never went down. So I threw the SC back on and same probelm again. Jump start and car starts at 13 volts and slowly goes down to around 8 and then it wants to give out. After i turn the car off the battery goes back to 11.75 and it stays there. Belt is tight and the clip is wired correctly as per instructions on the forum. I'm very confused! Does this have to do with a longer belt or something? I know that doesn't make any sense but thats really the only major difference. NEED HELP! haha
Well you say you change one thing, the computer, with one computer the car charges, with the ohter it does not. Now either one computer works and the other does not or you are mistaken about what changes were made. If every thing is the same except the computer then I would say it is the problem. But then I am old and drink a lot. Larry
I changed the battery today and now the battery stays at 12 volts the whole time at idle. Its great that on and off, the battery holds a constant voltage. But unlike any typical alternator, the battery is not at around 13-14 volts at idle. Its like the alternator is half working or something?
