I have a 1990 Accord LX with about 377K miles.



You got me beat. I've only got 260,000 miles on my 'Teg. Bought it new,
too.



It has been a great
car, but now the Charging system light (the red light with a Battery
icon) has come on (and stays on). I read through the Owner's manual
and Hayne's Service manual. The Owner's/Service manual suggest
tightening up the fan belts, which I have done - no luck, the Charging
light still comes on. Any ideas what is causing my problem??



Does it come on when the key is first turned to ON, and remain on
thereafter? If so, it means the system is not being charged by the
alternator. This does NOT necessarily mean the *alternator* is bad...



I have replaced a few parts charging system-related in the past.
Here's a brief list:
- fan (drive) belts - 330K miles
- new battery 322K miles



Not really part of the "charging system", but if bad, will overwork the
alternator.



- new ignitor, coil, rotor - 270K miles



Not part of the "charging system".



- new voltage regulator, alternator brushes - 248K miles



Ohhhh, the voltage regulator failed? Interesting. How many times has the
battery been allowed to run flat?




The alternator is original, and I suspect that's my problem.



Could be, but you need to test this hypothesis with a multimeter. If you're
over 13.5V at 2,000 rpm, then the alternator is probably fine. Anybody do
any basic checks with a VOM?



It looks
pretty simple to replace, but I wonder if it makes sense to go through
this expense. The car is due for a timing belt replacement (at $785),
and I just do not know how much longer it will last (original engine,
transmission, clutch). The clutch currently shows no signs of
slipping, but that's the next big expense I am anticipating.



If your clutch is original, I'll eat my hat. I got 255K out of mine and
every mechanic I've talked to says that's a record for them.

This car must have spent nearly 100% of its time cruising on the highway.
That's the only way you could get 377K out of your tranny bearings.
