If it should turn out to be a VR don't feel bad since yours is a '98.
The VR went out on my '13 last year with less than 25,000 miles on it.

Mine was probably one of the leftovers from the model '12 year where that had so many bad defective units.

A big thanks to all y'all for the quick help. I haven't had a chance to get back into the issue. When I do I'll follow up with what I find.

One more symptom I just remembered is that every time the gauge drops to 8 I get some serious popping and crackling on decel. Would sound kinda cool if it was a drag bike or some such thing.

(After this is figured out, does anyone want to admit to understanding Brit bikes in general and Norton in particular?)

Thanks to everybody that replied!!! This is the first opportunity I've had to get back on here in awhile.

I checked the actual voltage delivered to the battery compared to what the gauge was telling me and found that it was getting around 14.2 volts at 1800-2000 RPM. Seemed good so I took the bike for a ride. While riding it a considerable distance (nearly 200 miles round trip) I found that tapping the gauge made it jump up to a more proper 13.5+ volts. Looks like I found my problem.

Wonder why I, or any of my friends that claim to be wrenches, didn't think of one of the easiest ways to test the gauge? LOL

Anyway, thanks to all for the quick replies to my original post!!


Doug

harley volt meters a notoriously inaccurate. you need to check with a hand held meter attached to the battery while riding. i taped a meter to the fuel tank and took a ride to see the harley gauge was inaccurate.

I hope you've resolved your problem. But the above statement makes me wonder if you really have. A sticky gauge won't cause backfireing.
