Scape to bare metal and reground all ground wires then make sure no hot wire has melted its insulation and is touching metal on ur bike,

It sounds like its possibly a bad regulator/rectifier. I have posted a link to a video on how to test your regulator. How to test 2 plug Regulator Rectifier for K6 K7 GSXR 750 600 1000

Gsx r 750 1998. Battery holds charge when riding with lights off. But not with lights on. Stator or rect/reg??


Definitely a charging issue. Always check the battery first, I prefer a gel cell battery over acid. Battery must be good and strong to charge properly. This charging system is so small , it only operates enough to maintain battery voltage. Normally it wont charge a weak battery, so start there first. you can check the voltage coming from the stator, at 3k RPM you should be getting around 60-80 volts per leg. If each stator leg checks within these results, it will be a good stator. The reg/rect is not something I can tell you how to check on the bike. We have a stand alone system here where we bench test them off the bike to eliminate the rest of the system to test Just the reg/rect.
I have these stators here new also have the reg/rect, both have a one year warranty. If you need more help let me know. Thanks

Hi I have a 2001 Honda shadow ACE motorbike. There are 3 yellow wires going from the alternator to the voltage regulator through a 3 pronged plug. They have become very hot and fried themselves at...


3) there may be damage that has caused this
2)doesnt matter which yellow wire
1)maybe fried regulator or stator coils or aged insulation which has allowed a short between windings

The three wires are the 3 poles of the stator windings,

Fix the wires and plug first(electronics shops will have suitable 3 or 4 pin plugs to use)
get a multi meter and check resistance, any pair should have same resistance, non should short to ground.
with the bike running they will produce AC current (maybe 50-60vAC)again any pair.
If you are getting good AC voltace, then put the meter across the battery 12vDC engine stopped should rise to 14 vDC (about) when engine revved to 3000rpm

No AC -new stator
No DC-new regulator
Note voltages are estimates, many bikes run very similar charging systems

I replaced the stator and rectifire in my 2oo1 r6 batt is still not charging why


check the voltage across the battery, should be over 12v engine stopped, and 13-14 v with engine running.
make sure the battery will accept charge from a battery charger. the stator should produce roughly 50vAC from any pair or the three phase wires( they are the three that are the same color)

Hi,I have a 1982 V45 sabre,the problem is the stator plug is getting really hot.checked the charging and it's between 13.2-13.9.is it normal for this plug to get hot?


Yes some heat is normal, not so hot that it melts. Your voltage from stator is AC not DC,the voltage you read was after voltage regulator.To check the stator output unhook the wires from stator,run engine at 1,500 rpms as you read Volts AC on your meter,read from one stator wire to the other (do not use black to ground) untill you have tested all the combinations,write down the different set of numbers.You should read around 45 or 50 volts AC on each set. The high temp on the wire is more likely the result of wire connections needing to be cleaned and treated with dielectric grease to keep out moisture and deture corrosion.With good clean contact the wire will have less resistance and be cooler.The hot spot is usualy the weakest. OK well hope you get it done soon,Ride safe!

Stator wire melted 98 GSXR 750


I guess its the regulator/rectifier thats pushing too many volts down that wire. Try another unit after fixing the wire

97 gixxer 750, will not start. Starts fill with


Your charger should be putting out 13.0-14.5 volts to keep the battery charged. Otherwise its running off the stator sometimes and the battery at other times depleating the battery. The voltage regulator could be bad or the stator could be bad. try swapping the volt regulator first and start from there. Also a battery that has been depleted should be sufficiently recharged before using it again.
