Hi, Rick your regulator must be properly grounded in order to check out any main electrical system, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary. "WARNING" never plug or unplug any electrical connector with the engine running !!!
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is "GROUNDED" and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

Hi, Janrakus before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries.
1. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
To do this with a meter: black lead to battery ground, red lead to each pin on the plug, start with the voltage scale higher than 12vdc and move voltage scale down in steps for each pin. Any voltage is a bad regulator.
3. On the other part of the disconnected regulator plug. Set the multimeter for Ohms x1 scale and measure for resistance across the pins of the stator. You should read something around 0.1 to 0.2 ohms for a 32 amp system.
4. Then check for continuity between each pin on the plug and frame/engine ground. The meter needle should not move (infinite resistance)(digitals will show infinite resistance) if the meter needle does move (indicating continuity)(digitals will show some resistance), recheck very carefully. If the meter still shows continuity to ground the stator is shorted (bad).
5. Set the meter to read A/C volts higher than 30 volts (the scale setting for voltage should always be higher than the highest voltage you expect or you may fry the meter). Start the bike, and measure from one pin to the other on the plug (DO NOT cross the multimeter probes! - touch them to each other). You should read roughly 16-20 vac per 1,000 rpm.
6. If the battery was good under load test, if the stator is NOT shorted to ground, and the stator is putting out A/C voltage, then the regulator is bad (most likely even if passed step 2)

VERY unusual for a 6 volt system, they just do not work. Count the fill holes, usually there will be 6. Think 2 volts each. To be sure, hook up a volt meter and see, but it just HAS to be 12 volts. Been that way forever.
only do this if the parts are made to let you do it? the charging systen is still going to be at 6 volts no hope of charging a 12 volt battery is there? and the ignishion coial is 6 volts as well, has it got a starter fitted??? well if it has thats also 6 volts? stick 12 volts in it its going to burn out prity fast now then? still wont to go over to 12 volts????
Esage, Whoa! If you try to use the mattress pad that used to plug into the house wiring and make it work from your motorcycle wiring you will not get the result you want. The house supply is 110 Volts AC and the motorcycle is 12 or 6 volts DC. I can help you make what you want but we would have to start from a different direction. First start by telling me what kind of battery you have on the Harley. I wonder if there is enough juice for a thing like a heater. When you charge the battery what settings do you put it on 6 or 12 VDC?
Also You may want to go to a Cabella's store and see all the stuff they have for deer hunters to keep warm that run on batteries and you would get some ideas to use real quick.
