Hello everyone,
I have Kia Forte 2014 LX, 1.8 engine, automatic.
I'm having issue with my battery. I have installed brand new battery on 31 March 2022 and it drain if I don’t drive my car for at least 3 days (working from home), I'm having trouble starting it normally. Need to jump start. I had the same issue with my old battery and then the battery itself not holding the charge so I decide to change it.
I'm not a mechanic, but can do basic troubleshooting with help of forums and YouTube videos.
I did the following tests and every things seem to be ok, except for 2 things.
- I have 9 inch screen aftermarket radio/head unit is installed with backup camera. And it was draining the battery so I decide to remove the 15 Amp (Multimedia #1) fuse from passenger compartment fuse box. No power in radio, don't use it for now.
Question: Is removing the 15 Amp radio fuse (multimedia #1) will stop the draining? Radio is still connected.
- The 7.5 Amps (Memory) fuse, does NOT goes to Ohm 0.00, it stays at between 0.09 - 0.11. So little draining here. Also replaced "Memory" 7.5 Amp fuse. Following are connected on Memory fuse:
Driver IMS Module, Driver Smart Key Outside Handle, Passenger Smart Key Outside Handle, BCM, Tire Pressure Monitoring Module, Auto Light & Photo Sensor Instrument Cluster, Data Link Connector, Multipurpose Check Connector, Digital Clock, A/C Control Module, Electro Chromic Mirror, Driver Power Outside Mirror Passenger Power Outside Mirror
See attached pictures.
What could be the cause of the draining?
Any help would be appreciated.
Thanks for helping.
