I too have a '01 Caravan and just had similar problem all instruments and headlights would work but no start, battery was replaced and it was noticed that acid had leaked onto the wiring harness [located directly below the battery box] poor design choice by Chrysler the shop which replaced the battery under warranty refered to dealer.
Dealer was able to cut and splice/solder the wires tape and all components were back in working order.
However at a cost of $520.00 4 hours at $130.00
