I have a red box boyer. As I recall it's a microdigital from the 1990's era. I also have an ammeter on my bike. I'm getting an intermittent issue where the bike doesn't start. The ammeter shows a drain on the meter just as I kick the engine over. If I turn the key on, the ammeter shows no drain with the lights off. The minute I roll the engine over with the kickstarter, the meter goes to the negative, showing a drain and the bike doesn't start. After a few seconds of the ammeter needle pointing into the negative, it pops back to reading Zero again... My thought is that the boyer is "asleep", even with the key on, but when the engine rotates, the pick up causes pulses that "Wakes up" the boyer and thats when the ammeter jumps to the negative. After a few seconds of no engine rotation (when the bike doesn't start) the boyer shuts off because there's no rotation, so no trigger signal is being sent to the boyer. Does this sound like a fair discription of how the boyer works? This negative ammeter behavior hasn't been the norm in the past. I wonder if I have a shakey connection on the boyer circuit or if the boyer's circuitry is dieing a slow death. Other thoughts are a bad cell in the battery causing some issues. I balked at buying a new battery the other day, even though one cell was low on water and the battery is pretty old. The ammeter definately indicates it's charging more strongly than usual and I keep the bike on a battery tender when it's parked... I guess I'll break down and buy a new battery and see if that helps. Ideas? comments?
