Last November I purchased and installed a new voltmeter. Granted I went for a pretty cheap one on EBay (less than $10.00) but it was waterproof and supposed to be fine for motorcycles. Unfortunately it seems it is not suited to the new normal of exceedingly hot days. My bike seldom sets in the direct sunlight for more than 30 minutes straight (while I am in a store) as I only take short trips around town and for my own comfort (the seat gets hot) I try to park in the shade whenever I can. I doubt if it is still waterproof but it does still work. Although due to distortion it is a little hard to read. Any recommendations for one with a glass lense?
