Tried to install dashcam and took out my clock and radio display
Wondering if anyone has any advise before I take this to a shop and have to pay for someone to help me.
I was installing a dashcam on my 2013 Toyota Corolla using a hardwire kit. It's the Rove 4k dual dashcam.
My first thought was to use slot 12 (25a) "ACC-B" for constant 12v and slot 23 (15a) "CIG" for the yellow ignition power.
When I pulled the fuse for slot 23 my voltage meter didn't detect any power from either end. I thought maybe it wasn't in use and instead pulled slot 1 (15a) SEAT HTR and connected my yellow to that.
I then tested it out by turning on the car and the dashcam worked on startup but not on standby, and I noticed my clock, radio display, and cig charger all had no power. All my other lights seem to work and are functional along with doors etc.
I swapped from slot 12 to slot 22 (20a) "Sunroof" for constant 12v (because I dont have a sunroof) and that seems to work fine for the dash cam. However replacing the fuse in slot 12 didn't fix my clock and radio.
So I'm currently left with a working dashcam which is great but no clock or radio which is sad. I'm looking for guidance on what to check for.
My two theories are either
- the slot 23 "CIG" controls all 3 of those and by pulling out the fuse I damaged it which is why my voltage read no power at all in that slot.
- Slot 12 "ACC B" controls all those and was blown/damaged when I swapped in that wire initially.
However neither fuse "looks" blown from my amateur eyes at least, and I'm unsure how to verify what else the issue could be. Tried to look up the mappings for what controls what but seeing mixed answers. Hoping someone has some good advice I can try to make my DIY a success not a failure.
Pictures are of my fuse box label and initial state of the fuses. The only difference now is the wires in 1 and 22 which are working.
UPDATE:
I got my fuse tester and tested all the fuses both on the inside of the car and under the hood. They all came back good. I also flipped the ones that were reversed.
While I was doing this I did confirm that both 17 and 23 don't read any voltage on the voltage meter when the car is turned on, so I assume something is interfering with the electricity running to those slots that is not fuse related.
