Re: [AMC-list] Reversed Battery Connections! What did I do???

[danritz@xxxxxxxxxxx]

 I'm no expert on this but... I would guess that when the
battery was incorrectly connected, the ignition key was in the
"off" position.  If so, wouldn't that alone have prevented
damage to the majority of the circuitry?  Wouldn't the juice have
stopped at the stater relay and/or the ignition switch, except for devices
that are powered on when the key is in the "off" position?

> Check all fuses first. How did you run power to the fuel pump? Find
the power wire and jump directly to the battery and see if you get fuel
pressure. There's a good chance that you shorted the ECU though,
unfortunately. The fuel pump would probably survive reversed polarity for
a second or so, the ECU, however, probably didn't like it at all! But
check the fuel pump circuits first. Oh, since you mentioned the solenoid,
does it click when you turn the switch on? If not, the damage stopped
there! Since it was smoking, there's a good chance you just burned the
solenoid up.
