I was benchmarking my stock stator (2001 model, with 9,000 mi.) last night, and I wonder if it's dying. Across each of the three coils, from 2000-6000 rpm, I measured 9-13 Volts AC. This was measuring across the yellow wires on the regulator/rectifier plug. I was expecting a lot more than that, about 50 VAC at 5000 rpm. So is it dying? I bought a 400W Electrosport stator & regulator/rectifier and wanted to get a baseline reading before installing the new parts. thanks, Chris

Volts AC. Unless you were using a true RMS voltmeter ($$$ Fluke or some such), your voltage measurements are going to be bushit. Unfortunately the voltages you get out of a stator are not going to be a nice pretty sine wave like the stuff in a wall socket, so your little $10 Radio Shack DVM (which is set up to measure nice sine wavey wall socket voltage via a process of diode chopping and averaging) is going to be utterly confused.

I doubt it, since these are windings, they usually open or short. They usually do an "instant death" and don't slowly die? Shorted turns could cause the problem, but continued use would probably make them overheat and open? You really need to use a TRUE RMS voltmeter with know specs for that measurement. Most voltmeters assume a low frequency sine wave. They are calibrated to that and get way off for anything complex. You can not depend on any data take with a standard DVM. Best would be to use an oscilloscope. Borrow one if you can?. Digital is best because you can save your data for reference. You can see the peak voltages, not just some average of all the pulses and spikes. Mike Crestline, CA 2004 - "eBay Red" "WE HAVE ROOM FOR BUT ONE FLAG, THE AMERICAN FLAG.

I forgot this in my previous reply. Because of the complex measurement, manuals usually have you measure the DC Resistance of the windings. They know about the length of wire on each winding and the size, so the resistance is pretty consistent. Be sure to measure it at the temperature the spec says (25C?). Low ohm values are tricky to measure. You have to take into consideration you test leads. They may have 5X the resistance than what you are trying to measure. I like using a power supply with a constant current, say 0.1 or 1 amp into the lead and measuring the voltage at the winding. One Amp makes One Volt into One Ohm. Good old Ohm's Law! You can use a resistor or extra light bulb from your battery to limit the current. You can use the DC current function on your DVM to measure the current. It is best to have 2 DVMs, so you can read Current and Voltage simultaneously. Mike Crestline, CA 2004 - "eBay Red" "WE HAVE ROOM FOR BUT ONE FLAG, THE AMERICAN FLAG.

Ah, thanks. I was using my $20 Craftsman DVM. To baseline my current system then, is loading it until the voltage at the battery drops the only good way then? This all may be more effort than it's worth, I just wanted to see if I could measure the improvement from adding the high-output Electrosport stator. thanks, Chris ---------- Original Message ---------------------------------- From: "E.L.

It's not uncommon to see many Harley's followed in numbers by Goldwing's in small remote towns in Mexico. I used to be surprised, now I think oh they like to ride and take in the culture just like I do..One of my favorite memories was watching two Harley's riding up and down the boards over steps into Margarita's courtyard in Creel before the courtyard was closed off. Probably as memorable as an FJR and Concours going in... ,_.__JF_,___
