To hardwire the DR900S-2CH, the instruction manual says to choose a fuse that relates to accessories, like a cigarette lighter or stereo. It also says this should be 20 amps. My new car has an interior fuse box for such things under the steering wheel like most vehicles. The problem is the only 20 amp fuses have to do with the door power windows. The one for the cigarette lighter socket is only 15 amps. When I tried the 15 amp cigarette lighter fuse and set up the hardwiring, the B-124 I have connected to the dash cam, said it was too low on voltage. I tried all the other 10 amp fuses and it was if the B-124 was not connected at all. And on top of that the power window for that fuse would not even work.
I'm wondering if newer vehicles are moving away from accessories that are 20 amp and going to 15 amp. The reason why I want to hardwire the battery is because it would charge at 9 amp instead of the 5 amp with a cigarette lighter socket. My commute to work is not that long and I never get a full charge on the battery to last the day at work or after work as the battery dies in the middle of the night.
What possible solutions can I do besides plugging directly into the cigarette lighter?
