[QUOTE="ionbeam, post: 1263555, member: 277"] I agree, it sounds like the starter. The fastest way to determine that is to put a current probe on the battery and read cranking current. A dealer should be able to do this, I have a current probe in my tool box. Lacking a current probe you need to do some structured testing with a volt meter to determine the real root cause. If the starter is really going bad, hooking it to a car battery should take care of that. Look for the smoke, it will be a race to see if the starter cooks before the wires melt. It bothers me that #1 a starter is bad at 20k miles (it does seem to happen with some Gen II bikes) and it bothers me #2 that the symptoms remain the same with two different batteries. A loose battery cable or bad battery cable would cause the same symptoms as you see with the meter assembly blanking... And, I assume that the clock and trip odometer reset too? [/QUOTE]
