s14 rb25det

I just got a r33 rb25det swapped into my auto 95 240. When i was driving it home from the shop i got the swap done at, i noticed that the engine was starting to bog down once i started using the windshield wipers and headlights. i had to recharge the battery 3 times just to drive an hour. at first i thought that it was the alternator,but i took the alternator off and got it tested at advanced auto parts. the alternator ended up being fine. Does anyone know what the problem would be or could be. If you could respond ASAP, i would greatly appreciate it. Thanks

The alternator wiring is probably all farked up....Ask the installers if they used the KA lower harness or the RB lower harness...

If its the RB its probably not wired correctly to charge the system.
