1997 Mercury Sable Repair Question
New alternator and new battery. the alternatoris not charging the battery.
With the key on, any voltage at the I terminal at multiwire connector? I looked at info for a motorcraft generator.
Charging system wiring, below.
started car and no voltage on the I terminal
There may be a problem with indicator lite or wiring. The info shows a resistor to bypass the lite incase the lite-bulb vibrates out socket, or goes out. Does the charge lite on the dash work?
I've seen diagrams like this before, with the bypass, generator would not charge unless lite was fixed.
the light does not come on. It came on originally when I had low voltage on the bad alternator. I replaced the alternator and the light went out. I assumed it was because i fixed the problem. According to the owners manual the light should come on briefly when the key is turned to the on position. It does not! Is there a fuse I should be looking for to replace?
The fuse is in the diagram, goes hot/voltage with key on. If fuse is ok, use voltage tester at fuse leg, where the fuse plugs in.
you are the man! replaced the fuse and alternator is charging the battery to 14.25 v
Thanks a lot.
Glad you got it going your way. Hope the fuse doesn't blow again? Maybe it was the old generator that caused it to blow?
