electrical problem in 95 Jeep

I had some corrosion on the cables and posts of my battery. I cleaned
them w/ baking soda and water. Before I removed the cables from the
posts my emergency lights began to flash. I installed a new battery
and thoroughly cleaned the cables. The flashing continued when I
reconnected the cables. I started the Jeep and it died after running
for only a few seconds.

 

Used Jeep? Perhaps the previous owner installed a security system that has
a fuel cut off?

 

What do I need to do to reset it?

 

Check your alternator at autozone

 

sounds like the factory alarm is going off
place the key into the drivers door lock and then lock and unlock the door using
the key if that doesn"t work do the same thing in the pass. door
