Replaced Alternator 92 Sc400

[DaveMcKenz]

I was having troubles with my car gradually loosing its charge. Every week or so I was hooking it up to a battery charger and I would be fine for a while and then I'd need to do it again. I cleaned all my terminals but no change. I decided i had 100K on my original alternator so I'd take a chance on replacing it. I bought a rebuilt nippondenso on ebay for $105 shipped.

I was very pleasantly surprised by the simplicity of replacement:

Disconnect battery ground

Raise front of car and remove belly pan

14mm wrench to loosen tensioner and remove serpentine belt

14mm wrench to loosen one nut and one bolt on front of alternator, from above

12mm wrench to remove B+ cable from alternator (from below)

Unplug other cable from alternator top rear (from below)

You can now push alternator forward off mounting stud and wiggle it out (from below)

You may need to release a soft line fixation point to make room to get alternator out

Replacement is the reverse and actually easier. Time will tell on improvemt in charging system. Thought someone would like to now how easy this is. It took me 1 1/2 hours and I'was never in that area before.
