Motorcycle Multi-functional 2 in 1 Digital Display Voltmeter + Electronic Clock, 6-30V IP67 (Green Light)

Voltage meter

I chose this because it is one of a few 6v meters on the market. Unfortunately for me the instructions were clear as mud, and took a few times of imput to actually understand exactly what I was doing. As for mapping ? Not got any response yet,so that part is wasted on me. I just wanted a simple device to tell me if my motorcycle was charging or not. Flashing lights to me are pointless. This is in no way I am saying the product is not a very good meter, just a bit of a faff . Fitted to a 1955 bsa, it lights like a Christmas tree....but nothing else. But me being as old as the bike...not surprising I find it a overcomplicated.
