75/15 Yellow Flashing

New 75/15 (non bluetooth) connected with no jumper to a AGM 120amp battery without a load or panel connected and i get a consistent fast flashing yellow led??? DOA?

Tried reset battery disconnect and googled the hell out of it with no joy.

Cheers Geoff

@JOF062, without PV connected the device will not be charging, obviously, so I wouldn't jump to any conclusions about whether it's DOA or not before you complete your installation. Under normal operation, a fast flashing yellow LED indicates bulk charging.

Ok seems to charging fine but the Yellow LED continues to always flash with only the battery connected even when fully charged. Will make JST-PH 2.0 lead to usb lead so i can see whats happening in the back ground on a pc.

Thanks for the reply,

Cheers Geoff
