I noticed last riding season that I was getting less and less range from my bike. I commute just under 5 miles round trip to work. It was getting to where I couldn't make that distance full throttle in 'go fast' mode with a full charge. I was a heavy 240 lbs back then (30 lbs lighter now), but the range shouldn't be THAT short.
Since it was the end of the season, I didn't fret about it and at the start of this season, I bought two fresh batteries. I put them in and charged them overnight and then tried to ride the bike. I had a full set of bars but by the end of the driveway I had nothing but one bar and a blinking bar. When I shut everything off, I got 4 bars. Let it charge for a week and tried it today, same thing.
I just put the other batteries in to see if it is the batteries (I didn't think to test them before I removed them) and I will test them tomorrow.
I read some on this in another topic and the charger light is behaving in the same way, constant green, never going to amber. (I haven't tried disconnecting the batteries and plugging it in; it is dark now, but I will try that tomorrow).
If it is the charger, what do I test? I have a nice voltmeter, but do not understand it that well. If someone could give me a clue on what setting I need it on and what terminals to test that would be great. I want to be sure it is the charger since that is an expensive article to replace and I just put down over $150 on the batteries already.
Any help would be appreciated. Thanks.
