Next Gen Ranger Raptor battery issue! Please help

[RaptorChe]

Hi. I have a 23 Next Gen Ranger Raptor and least week the battery went flat. I jump started the car and used it for the day. (All the sensors were going off al day) next day, battery flat again. So I went out and spent close to $600 on a brand new battery. Drove it for the evening, next morning, new battery dead… any help or thoughts?? I’m going crazy

Well, there are two possible scenarios.
1. Your alternator is not charging correctly (low or high voltage) - measure the voltage on the battery with engine running= should be above 13.5 VDC and increasing with the engine revolutions.
2. Could be current leakage - with the car of, disconnect the battery positive terminal and connect an amperemeter in series to measure the current - should be no more than 50mA.
If it is more you need to start remove fuses to find out from where the leakage is coming from.

Hope that helps

It isn’t the alternator if he drove it the rest of the day after the jump.
