An electrical ignoramus looking for help here...
I've installed the Honda 12V under-seat accessory socket, which is basically a plug-and-play installation. No wire stripping/soldering, etc. required, since the Honda accessory connects directly to the OP behind the battery. The Honda accessory socket harness includes a 3A in-line glass fuse :frown:
Time to verify it all works...
If I just connect the SAE voltmeter/USB charger to my direct/unswitched battery tender SAE lead (with its own 7.5A blade fuse) it works fine. However the point of the Honda accessory was to be able to use switched power, so I'm wondering where the problem might be.
* - I took the SAE 12V adapter apart to see if it's fuse was okay (it was); the voltmeter/USB charger can't be disassembled.
The voltmeter/USB charger is dual 5V/2.1A, so could draw 10.5W, which is less than 1A at 12V, so I wouldn't expect it to blow a 3A fuse.
What am I missing?

- I connected a 12V-SAE adapter to the socket, Ignition on and indicator light on adaptor lights. Ignition off
- I connected an SAE voltmeter/USB charger to the adapter. Ignition on: Indicator light flickers and 3A fuse blows. Ignition off

- Battery tender SAE lead (7.5A fuse) => SAE voltmeter/USB charger <<= this works fine, not switched
- Bike switched harness fuse (7.5A) => OP connector => accessory harness fuse (3A) => SAE 12V adapter fuse (10A)* => SAE voltmeter/USB charger <<= 3A fuse blows when ignition switched on
