Question about Harley Davidson FLHT Electra Glide Standard Motorcycles
Hi Flattopmike1, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at "BOTH" ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.

SOURCE: fuse box
Looking at the bike from the front, it is located under the side cover, on the right hand side, you we need remove saddle bag. Once removed the fuse box is located under the plastic cover.

Here's a few things that I would check. Now, I'm not that familiar with the computer controlled bikes like your. I work on the old bikes, those made prior to 2000.
First, check the plug where the regulator plugs into the stator on the front of you engine down my your oil filter. These plugs are notorious for getting oil in them and for coming unplugged. Buy yourself one of those little metal things that keep the plug plugged in. Also check the plug for a broken wire internal of the insulation. I've seen the copper wire be broken up inside of the plug but yet the insulation and the plug itself look fine. It's difficult to find but I do it by bending the wire and feeling of the "resistance" to being bent. If it bends too easily, it might be broken inside.
Next, check the ground on the regulator. I like to put one of the "star" type lock washers between the regulator and the frame on both bolts that hold the regulator onto the frame. The regulator must have a good ground.
I would tell you how to test the stator but since you problem seems to be so intermittent, it's going to be difficult to "catch" the problem. I doubt seriously that your battery is tripping a breaker. If a breaker were tripping, this would reduce the load on the battery causing the voltage to go up, not down. Now, if you've got something drawing too much current that might cause the voltage to down until the breaker tripped. Watch the volt meter and see if the voltage goes up and down in a rythmic cycle. If it does, find your circuit breakers (usually under the seat) and start the bike. Watch the volt meter and feel of the breakers. When the voltage changes, you should be able to feel the breaker trip. You might even be able to hear the slight "plink" noise it makes when it trips. Good Luck!

Everyone has their favorite spark plugs and oil. As for spark plugs, I like NGK plugs because I've had less problems with them than any other plug I've ever run.
As for oil, it depends on whether you're talking petroleum based or synthetic. Aftermarket petroleum based, I like RevTech. Aftermarket synthetic Mobil V-Twin.
