It is similar to this one

My coworker has a 2003 Jeep Liberty. She is having a weird issue with it. It cranks weak when she has a short trip but is fine when there is a longer time between starts.

For example she drives to work and it’s fine when she starts it at her house. Then she works for 8-9 hours and when she starts it after work it is fine. However, if she goes to the gas station after work it will crank slowly and have a harder time starting.

She got a new battery about a year ago. I was thinking maybe it’s an alternator problem or something with the starter. I was planning on bringing my multi-meter to work next week to see how many volts it’s putting out.

Any ideas Oppo?
