Hi, Rhall20448 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. Battery Test:
The battery needs to be a fully charged and load tested to ensure proper readings, connections need to be clean and tight. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Standing battery Voltage should be 12.5-13.2 DCV.
2. Charging System Voltage Test:
Start motorcycle, measure DC volts across the battery terminals you should have a reading of approximately 13.2-15 DC Volts.
3. Connections and wires:
Inspect the regulator stator plug, and check the battery terminals for connection corrosion. If everything seems to be in order, move on to number 4 below to determine if there's a failed component.
4. Stator Checks/Rotor Check: Each of the following tests isolates the Stator & Rotor. If AC output and resistance test fail and stator test passes then the rotor is at fault (Pull Primary covers and inspect rotor for damage).
5. AC Output Check:
Unplug the regulator plug from the stator start motorcycle and change Voltmeter to AC volts. Probe both stator wires with your meter lead. The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. Reading will vary depending on system, check service manual specification
Generic Specs:
22 amp system produces about 19-26 VAC per 1,000 rpm
32 amp system produces about 16-20 VAC per 1,000 rpm
45 amp system produces about 19-26 VAC per 1,000 rpm
Stator Resistance Check:
Switch your multimeter to Ohm x 1 scale. Probe each stator wires with meter leads and check resistance on the meter.
Resistance should be in the range of 0.1-0.5 Ohms. Reading will vary depending on the system, check the service manual for specifications.
Generic Specs:
22 amp system produces about 0.2 to 0.4 ohms
32 amp system produces about 0.1 to 0.2 ohms
45 amp system produces about 0.1 to 0.2 ohms
5. Stator Ground Check:
Switch your multimeter to Ohm x 1 scale.
Probe each stator wire with your positive lead on the multimeter and the negative to ground.
There should be no continuity to ground on either wire.
If there is continuity your stator is shorted to ground and must be replaced.
6. Regulator Test:
Each of the following tests isolates the regulator only, so if any of these tests fail, the regulator is at fault.
Identifying Wires:
Battery Charge Lead- Wire going from regulator to battery positive.
AC output leads- Wires coming from the Stator to the regulator.
Ground- Wire from Regulator to ground or regulator may be grounded via the physical bolting to chassis.
Regulator Ground Test: Ensure the regulator body is grounded or grounding wire is fastened tightly to a good ground (you should verify this by checking continuity from regulator body to chassis ground).
Fwd/Reverse Bias Test/Diode Test:
This check is testing the Diode function to ensure it is regulating the AC current for the stator into DC Current.
Switch multimeter to Diode Scale.
Place your Multimeter positive lead on each AC output wire.
Place your multimeter negative lead on the battery Charge wire.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the AC output wires and the Positive lead on the Battery Charge Wire. The reading should be Infinite. With your meter on the same setting, place your multimeter positive lead on the regulator ground wire or to the regulator directly, and then place your meter negative lead on the AC output leads.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the regulator ground and the Positive lead on the AC output wires. The reading should be Infinite.
Note: Below is a table to show the readings:
Positive Lead Negative Lead Reading
AC output 1 Battery charge lead Voltage
AC output 2 Battery Charge Lead Voltage
Battery charge lead AC output 1 ?
Battery charge lead AC output 2 ?
Ground AC output 1 Voltage
Ground AC output 2 Voltage
AC output 1 Ground ?
AC output 2 Ground ?

SOURCE: i installed a new stator/generator and a voltage

Hi and welcome to FixYa,

The heating up would be normal as relatively, high current is passing through these wires/terminals not only to charge the battery but to power the electrics of the bike. If the regulator is working correctly, it would soon dwindle down since presumably the battery has been charged. Almost always, the connector used is not plastic but phenolic or epoxy based due to this very reason.  Another possible reason for excessive heat is that the terminals are not tighly fitted to its counterpart connector. A loose connector would result in a slight voltage drop but high current accross the connection.

Good luck and thank you for asking FixYa.

SOURCE: wire connector between stator & voltage reg/rectifier burnt

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

Check the out put of your regulator/rectifier, though rare with honda r/r's since they are made very well and rarely break down ( at least the older model ones ) it could be what is causing this unless you have a short circuit in your wiring harness.

Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery must have 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 batteries fail in this scenario more so than lead acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.

2002 honda 1100cc shadow sabre What is the purpuse of the rectifier? Bike runs great for thirty miles on charged battery then quits. While running disc pos. lea to battery an bike quits. should it still...


On motorcycles the regulator/rectifier are usually one unit. The voltage regulator takes the juice coming from the alternator and converts it , usually from a higher voltage, to 12 volts. The rectifier takes any extra power left over from the conversion and dissipates it in the form of heat. Honda motorcycles draw power from the battery to run everything on the motorcycle. When you disconnect the battery it is like turning off the key. If your battery is not charging check the alternator first. Find the plug coming out of the engine with three yellow wires. You should have continuity between any combination of these three wires. You should have no continuity between any of these three wires and ground. If If you get no continuity between any of the yellow wires or you get continuity between a yellow wire and ground , you need a new alternator. If the alternator checks good and the battery passes a load test, then you probably need a new regulator/rectifier.

Replaced two new batterys after batters discharge bike dyes i believe alternator is defective. is this a repair i should attemp in my garage as a certified small engine mech.? would i save that much doing...


well if you a cert small engine tech you shouldnt be asking this...

Start the bike up and check to see if its charging 13.4 over if it is, its charging. Now check for a current discharging the battery using a amp/ multimeter.
If its not charging, check for battery voltage at the regulator, red and black it sould be the same as whats at the battery if not check for bad wiring and the earth lead. If the bat voltage is OK unplug the reg run up the engine and check for voltage with meter on AC at the 3 same coulor wires yellow or white this comes from the Alt cover you should have 18 -40volts AC at 2500RPM if this is correct on all 3 wires (test any 2 of the 3 wires) if this OK suspect the regulator

NOT CHARGING JUST REPLACED REGULATOR NOT PROBLEM


if you have a multimeter conect it to the battery with the motor running at idle it should show 12 volts on increaseing the revs youshould see it climb to approx 13.5volts if it fails to do so you need to test voltage output at the alternater I think that is were you will find the fault also you might want to have your battery load tested if it has one or more colapsed or sulphated cells there is no way it will charge
