Hey, guys,
I use my JTV-59 Variax infrequently (basically only on Sundays when I need a banjo or I'd need more than two other guitars), so I make a habit to always check the battery the night before I use it. Two weeks ago, the battery indicator was at two lights, so I popped the battery into the charger before I went to bed. In the morning, the lights on the charger indicated that it was finished charging, so I popped it in the Variax and hit the battery level button. A brief, instantaneous flash of all 4 LEDs, nothing else. I hit the button again and get each LED lighting up and turning off sequentially - 1, 2, 3, 4. I hit it a third time, and the LEDs flashed in this order: 2, 1, 1, 2. The flashes were longer this time, as if this were a specific error message. A fourth press starts the cycle again, but with a slightly longer initial light up of all 4 lights. I used it that week with no problems whatsoever (I had a backup guitar, though).
I checked it last week (ended up using my Strat because I threw my back out and didn't want to deal with the weight of the Variax), same thing. I checked it again today as there's a tune with banjo on the setlist this morning. Same thing. I reinstalled the battery just in case it wasn't seated correctly - same thing.
What's going on here? I can't find any mention of those LED indicators communicating anything other than the power level of the battery.
