1990 chrysler imperial elec. problem

Somebody please help me stop dissing my car. My battery isn't
recharging, I have changed the alternator & belt. Does this thing have
a bad voltage regulator or computer chip ? when I charge the battery up
& start it the check engine light doesn't come on until the battery
runs down quite a bit, I can actually drive on the battery on full
charge for about 15 miles. I am a musician not a mechanic right now I
can't afford to put it in the shop so I MUST do my own repairs. So any
genius out there who hasn't killed over laughing @ me please respond ,a
big THANX 2 YA

 

The voltage regulator is in the PCM on that car. You should have the
charging system checked to see exactly what the problem is.

 

And if it IS a bad voltage regulator, there is a "recipe" running around
the 'net to splice in a 1971-up standalone Chrysler voltage regulator
(available at any parts store) so that you don't have to replace the
whole expensive computer board. Its not much harder than changing out
the pickups on a Les Paul or Stratocaster

 

do u have a digital voltage meter?? if you do i can walk u thru testing the
charging system

 

As this is an earlier model, you should be able to dump the codes using
the key-on/key-off method. The procedure can be found on allpar.com.
There is a code that indicates an open field circuit. I concur with
everyone else that this is most likely the problem, and if it is, an
old style voltage regulator can be installed for the repair.
