So today was connecting something in the car. I tried connecting via a fuse tap and using empty fuse socket from the fuse box. Checked volt meter was reading 12v. Great. But it would not power the box.
When connecting it off the cig lighter wiring .. which also gives 12v..it works fine.
Absolutely baffled as to why this is. First time was trying to tap off the fuse box. Watched many youtube vids looks like what i did was right and volt meter was confirming it.
Any ideas what it can be?
