HI All,
*Caveat here by saying i'm pretty awful when it comes to electrics but want to learn. I'd say the post is split into 3
1 - Parasitic drawn on Fuse 3
When i first got my jeep i kept having battery issues. I got a new battery and things were ok for a while, but now ~30 months later i'm having issues again where i need to keep using a battery jump pack to start if it's inactive after a few days.
The jeep does have a 12v shut off switch under the dash which i'll start using again, but i've been trying to diagnose the actual issues.
Checking it out earlier and found a power draw around of around 1.5a, i started pulling fuses and found the issue to be Fuse 3 in the engine bay. This seems to be linked to the ignition switch. Anyone able to help with where to start looking from here?
2 -Misc Wiring
I then found a wire from the +ve terminal of the battery to this relay. It's fused with a wire off to an earthing point
The yellow wire goes into this harness. Which then runs back into the dash. I assume this is the 12v shut off connection? Can anyone confirm this seems likely?
3 - No Power to Stereo
I've also lost power to my head unit. It was always wired up wrong by the previous owner as it didn't have a permanent power, and so would lose all settings when the ignition was switched off (Although i assume using the 12v cut off would ruin this functionality anyway?)
Following my crash last year, i now have no power to the stereo at all. Nothing should have changed from the wiring and it all looks ok. I've not started testing the connectors yet as i'm flying with work tomorrow and need the car first thing and last thing i need is to cause a problem! It could be that the crash has broken the stereo but seems unlikely. Any tips here in advance of me pulling out the dash/stereo and trying to fix the issue. Have confirmed it's not the fuse.
At some point i also need to remove the whole dash as i think the crash has broken the air vents. I've read some plastic can break off and fall down, as now i only have air through the small top vents on each side.
