I’ve been working to get my brother’s 99 up to par since we purchased it a few months ago. When the bike idles, the headlight works relatively well. Once the bike raises above idle, the light dims. Alright, so let’s check the battery. Battery is meh but not bad. Throw it on the charger for a few hours, let it sit a few hours after that and recheck. Battery still isn’t the greatest but it’s not to the point of replacement. Okay, I’ll swap my battery (from a 6th gen) with his and check. Same thing. Maybe my battery is shot too? Reinstall in my bike, twist throttle, light brightens. Okay so not the battery. Check the stator (stock), stator checks out and has ample and equal output across the three wires. Alright. Now I’m scratching my head and clutching at straws. I wire wheel the terminals and connections with my dremel and wire wheel the bolts. Nope, wasn’t a bad connection. I’m lost. Bike runs like a champ, maybe a little toasty, but it’s a vfr. Anyone have any idea?
