Nissan 93 pick-up. After crossed wires fiasco, jumped correctly. Car started and ran for 30 seconds before all electrical power died. Just dead battery...or damaged alternator / elec harness?

could be a damaged regulator, starter, coil condenser, or altenator...... good luck

#1 does the car now "crank with that battery in it (charged up)??
Next check,-does it "make spark" for the sparkplugs? This leads to fuses, and possible blown ignition system (the part under the hood). If it sparks when cranking (pull off a wire, - if individual coils,-- or center wire in distributer cap (and arc to ground) for this check. If you have spark,-the next check is to put a little gas into the intake near the throttle body (or carbureter throat!) Put the aircleaner back on to avoid singed hair in case of backfire!
If you get a "surge of power" for a couple seconds, the ignition (and probably computer) is ok. This would only leave "fuel delivery" as a problem (back to fuses again!) If you finally get the engine running, and the charging system is inoperative, - first check for "in line fuses" (some have large fuse - 50 amps or more in wire between the alternator output and the battery). If you find nothing bad there, - then take off the alternator and take it to an "auto supply house", and have them check it to see if it is good!
DO NOT go and buy lots of parts,-- and just keep putting them on till it works, you will spend lots of money for nothing! Find out what is bad before you start buying parts!
Next question is how much smoke was there? And did it smoke inside the car or just outside??
I have seen this before with another model Japanese car, and all that happened was that the battery "blew out a connector internally" and the car will not geneate power without a pretty near 12 volt input to the field coils (called a stator inside a alternator), -- so the car will naturally die on the spot!
Maybe the first thing to do if it WILL NOT CRANK, --and the battery checks "dead" is to put in another battery (from another car if possible), and see if it "fires up" and runs ok! It is entirely possible that you are getting excited over nothing!! (almost)

93 Nissan? Jap Scrap. Offhand it sounds like the voltage regulator. Some are built into the alternator. So, you might need a new alternator. Fried computer IS a possibility, but I doubt it. My moneys on the built in voltage regulator. Probably fried. So, you might be looking at about 160 for a new alternator. You could also try a junkyard. Best of luck!

The vehicle started and ran for 30 seconds.
This should rule out computer. Did the engine stop when jumpers were disconnected or did it stop while still connected ??
Disconnect battery terminals and put jumpers on terminals. do not use existing battery, see if it will run from outside source.
If so replace battery start and test alternator for charge, dash gage or volt meter, should put out 15 volts.

You might have fried your voltage regulator or badly cooked a connection somewhere. Could be inside the battery. Best have it checked.
