L1 & L2 flash white

I have just installed a new Power HAT but at power up it sits there with L1 & L2 flashing every few seconds and does not respond to the buttons. If I press S1 & S2 together the leds stop flashing, but it still does not respond to button presses. I have another power HAT which works fine. Suggestions for a fix more than welcome!

Hi @marc ,

This can happen when you insert the battery backwards. Did you do that?

It’s not even had a batter inserted yet, as I have "cracked off " the battery holder.

Could you please us an image of your hardware setup?

It’s just plugged into a Pi in the normal way. My other power HAT works fine
