i have a 93 fatboy and the plug was a little sloppy as well so i took a punch and spread the prongs apart however, what is the spring clip that you guys are talking about??

RE: Low voltage on gauge
My '93 had a clip on it when I bought it and it is installed on the engine mount bolt below the plug but I think it is either missing a peice off of it or it is the wrong clip all together because it doesn't come up high enough to even contact the plug. I have seen others clips on ebay that look like they may work better but I haven't purchased one yet to see. Best thing to do in my opinion is to bring your bike to the Harley Dealer and see what types that they have and bring them out to the bike to see which one will work the best.
Hey 93 bagger....have you had any problems with your voltage gauge dropping when you apply the foot brake? Mine does this and it seems like a common problem with the older electraglides. Drives me nuts and i haven't seen anyone that has found a fix yet.

Tbird,
How much does the guage drop? This is most likely normal. The guage reads the voltage inside the fairing, not at the battery, remember. With the brake on, you not only have the brake light adding additional load, but also the anti-dive air control valve kicking in. It is nothing to worry about. If it doesn't do it when you apply your hand brake, then you likely have a bad brake light switch in the handlebar control.

Dr. Hess,
The guage will drop from about 12.5 volts down to 7 or 8 volts. It comes back up when I release the brake and rev the engine up alittle. I do think I have a bad switch for my hand brake because it doesn't illuminate the brake light when I apply it. Do you think this might be what is causing the voltage drop with the foot brake? Whats so annoying about it is that when I apply the foot brake and the voltage drops down, my right turn signal will not work until I rev the engine up to get the voltage back up. If I put the turn signal on before I hit the foot brake then it comes on like normal and will work fine even when I apply the foot brake. I only have the problem if I apply the foot brake first and the voltage drops and then try to put the turn signal on.
Also one other thing is when my turn signal is blinking (either side) the volt meter will drop and raise as the turn signal light blinks. Weird!!!

Tbird,
You have a couple of issues here. First off, yeah, the brake light switch in your handlebar control is broken. The brake light and anti-dive valve should come on with either the front or the rear brake. The front is a mechanical switch. The rear is a pressure switch (unless things changed between your bike and mine). The switch isn't too bad to swap out, but I think you have to solder the connections. I took one apart last year when I changed out the throttle cables on the 883 and I seem to recall it being soldered in.
Next, 7-8 volts with the brake on is probably too low of a reading, and on top of that, your turn signal issue isn't right either. I'm going to say that they are both related. The problem is most likely a dirty/corroded connection. You can trace it out with a volt meter if you know how and find exactly the bad spot, or start at the battery, go to the starter, then the feed wire to the ignition, ignition to the various breakers, etc. Take apart each connection, hit the terminals with a little wire wheel on a Dremmel Brand Mototool, put a little Oxy-Guard grease on it, put it back together. The main breaker could also have an internal problem. It could also be the ground connection block. Basically, you likely have a single connection point that is dirty/corroded. You just have to find it. It would probably take me an hour to find it.

Much better! Exactly what was needed! I cleaned up the stator plug holes good and spread the regulator plugs a bit, globed some Silicone Dielectric Compound in the holes and put it all together. Tough to get at the motor mount nut. I hope I don't have to move this thing every time I change the oil filter.
Thanks for all of the replies!

RE: Low voltage on gauge
I too am having this same problem with voltage to the point that if I turn on the passing lights the gauge reads a shade over 12 or a little under 12. I have noticed that if I appl the front brake, sometimes the voltae will not come back up to 12.5+ but if I hit the ffront brake again, it will come back up to 12.5+/ A meter on the battery indicates 13+ volts going to the battery. BUt the same meter indicates less than that going to the volt gauge. Bike is a 95 Ultra. Put it in the shop and the mechanic can't find anything. Where would you start looking?
Thanks for the help

RE: Low voltage on gauge
Some of what you are seeing sounds normal, but if you have noticed it degrading, you should tak apart every connection between the battery and fairing and clean them. Not as hard as it sounds, just follow the wiring diagram. With age, corrosion starts setting in. I just did that on my 90 ultra. Also, it sounds like your brake switch may be sticking. I think 95 had a brake relay also, but it's not as common for them to stick.
