just did an engine swap and hooked everything up the same way as i took it off. and now my charging system isnt working properly ive been through 3 alternators so far. ive got a 2000 neon. been getting alternators from advanced, and getting ready to try auto zone.

 

Battery keeps dying I assume? Should only be a couple wires. Either your battery is dead or you're hooking it up wrong.

 

Do u have an aftermarket udp?
