I have a 99 jeep cherokee and my alternator harness is draining my battery do i need a whole new wire harness?

I am trying to go the cheapest route is there any way to just change the alternator harness vs.changing the whole wire harness?|||Why do you need the jeep if you are just trying to get it the cheapest way?? Sell it and buy Daihatsu Core, your gategory.|||i would change the entire wiring harness. but that%26#039;s just because i prefer to be safe and not have o go back and do it later.|||Changing the alternator harness is the best way to go and it is in most cases the cheaper way to do things. This may not last you as long as changing the whole wire harness.|||Yeah if it keeps being like that then you have to do it|||Are you sure it%26#039;s the harness? Usually it%26#039;s a component that causes parasitic drain on a battery. If you have to fix the harness, I%26#039;d suggest just fixing the broken wires rather than changing out the harness. It%26#039;s a bit more labor intensive, but a lot cheaper.|||did u try a new battery.if u did and it didn%26#039;t work take it in for repairs...im not rlly a car person|||You should be able to buy only the connector. Check with your local dealer. I would not suggest the junk yard. One from there would be worn out too. If you have buy the whole harness, you can splice the connector in, but you will have solder the connections to do it right. Good luck.
