voltage regulator

Where is the voltage regulator located on a 98 ultra tour glide classic?

Not sure on what a 98 ultra tour glide classic is, but on a 98 FLHTCUI it's directly above the front motor mount.

Thanks Smitty, It's an 89 not 98. charged the batt all day and just did a load test. it's only got 117 cca so it needs a batt for sure. and it's only charging 12.3 at 2500 rpm.        Thanks again,  Andy

If you lose the stator, it's not uncommon to lose the regulator also.  If you really need a regulator, I'd suggest that you replace the stator also.  I believe that in 1989 they went to the 32 amp alternator / regulator; if for some reason you still have the old 22 change up to the 32.  Look at one of the aftermarket web sites if you are unsure, the regulator plugs are different and they'll show you a picture and you can match what you have.

Yep, just happened to me on my trip out to CO and back.  Running about 60mph and the bike died.  Turned out the stator shorted out, then the battery ran the bike until dry, then the bike quit. Upon examination it was clear that the stator had also fried the regulator.
Put back together on the road at Black Canyon HD in Montrose CO cost was $710 including a new battery.  Only $240 for labor and about 4 hours in the shop, plus waiting about a couple of hours for parts...... in the shop at 8:30am, on the road at 2:30pm.

had it happened at home I'd have repaired it myself, but when 1500 miles from home .....

Installed new battery, volt guage is reading 10v with Ign. on even with battery voltage on new battery over 12v. Started er up and checked stator ac voltage at idle and 2000 rpm and they're in line with what i've been reading on the board, checked for short to gnd. on stator, no short to gnd. looks like it may need a reg but not sure how to check it, any ideas about the guage issue?

Well, I think on the Harley volt meter (if that's what you're referring to), I wouldn't necessarily trust it.  If you are really getting 10v to the fairing, you have a short somewhere.  Are your turn signals dull, hard to see?  Mine were and it turned out that I did have a short though I didn't know it (and the bike ran well, but just didn't start well all the time).

Uncover the battery, get a multimeter. Withe the test leads on the battery, check the voltage on the battery.  Should be 12.6v or higher.  Start the engine and run the bike up to about 1800 rpm.  With the test leads still on the battery, you should see something like 13.5v - 14.0v, and something like 25 or 26 amps.  I might be talking out my butt, that's about what I remember.  If you see these kinds of numbers, the charging system should be in pretty good shape.  I'm sure that someone else will see this and give you a better idea of the numbers that you're lookin' for.

I'm only getting battery voltage at 2000 rpm. battery is new and fully charged.
