This is a 03 ZX3 with 2.0 Zetec. Car won't start unless it is hooked to another vehicle with jumper cables. Battery doesn't hold a charge. Once it's running it appears fine until you stop. Once at a stop the temp gauge acts funny and some clicks can be heard around the instrument panel, especially if you use the turn signals. I'm thinking alternator here but wanted your thoughts. Got it home and shut it off and then tried to start and all I got was some clicking from the starter. Thanks!
