I have had a DGV which is a combined gear indicator and voltmeter on the bike for the past 2.5 years. During this time I have always had probelsm with batteries going flat and I am now on my 5th battery in just under 3 years. I got my dealer to investigate in case there was an earth leak and it seems that the DGV is responsible - drawing 17ma of current. Now it is disconnected battery is fine. Acumen don’t sell this product any more which suggests it has been problematical.
Has anyone else had this problem and have you had any success is getting redress from Acumen?. I put a message in their Contact Us box but have had no reply. I have now got a dud indicator on the dash, covering the hole for the cable. If they offered to exchange it for a gear indicator at least I would have that functionality and something to cover the hole.
