engine computer on 87 honda accord problems!!!

hello. i have a 1987 honda accord with a carberator. let me tell you the
story of this car. when i bought it it was in perfect shape with no problems
except that once in a while in very cold conditions, the headlights would
pause before they would turn on.
heres the problem and the details that i think are relavant.
a couple of years a go i took the car to have a windshield replaced. they
did an ok job but i noticed water leaking on my feet during heavy rain
downpours. one day i was driving in a heavy rain storm and all of a sudden.
all of the interior lights, radio started dimming. the idle was rough too, i
figured it was a short because every thing seemed starved for power and a
short would do that.
the next day my alt light came on. My theory was a short strained the alt
and overloaded it. i had the alt replaced and the car worked great until a
year later after another heavy rain the car did the same thing. the light
came on the next day....this time i had another alternator put it, but after
the new alternator was put in the alt light stays on and the car idles too
fast, and also, when you turn the ignition key off the car keeps running. i
have to pull off the ignitiion coil wire to turn it off.... my theory is
that the water damaged the engine computer and during downpours water drips
on it and cause shorts...can somebody with better understanding of hondas
give me some advice about what they think it might be. also , the alternator
on this car is a 3 pin type. if somebody were to pull the wires out of the
connector and put them back in in the wrong places would that cause this
problem?

 

Only the LXi has fuel injection, and a computer. Carb equipped ones
don't have computer controls.
I think you have many problems from wet fuse panel and wiring
connections. Will be almost impossible to fix. bob

 

This diagram is for an '87 LX. http://tinyurl.com/38vjv Although it is not
the same as on the LXi, there is still an electronic control unit present.

 

I had to go to the factory manual and learn about the cars with carbs.
I was wrong! The carb cars DO have an Emission Control Unit under the
drivers seat. It has 14 input signals from the engine, and controls 12
output functions. The outputs "control emissions and effect smooth
engine performance."
After re-reading your original post, I think you may be having ignition
switch trouble.
There are 129 pages of possibilities in the book for the fuel and
emissions systems alone.
Good Luck! bob
