rectifier regulator ..... 1983

[aaronmvrider]

battery reads over 11 volts when nothing running ( no lights and key off ).... as soon as i start the bike volts drop and if i turn on lights the engine dies......

[motoholic71]

The 3 white wires MUST read the same exactly AC voltage between any of them.

Very likely you have 1 of the 3 coils circuit on your stator burned or the faulty white wire is broken inside giving intermittent contact.

The fail of 1 of the 3 coil circuits will cause low voltage on the battery.

However that doesn't explain the engine dying unless the bike has an aftermarket ignition powered by the 12V circuit.

Or maybe a short between the stator coils and the ignition source coils deep inside the stator guts, thus joining the circuits

Or is this an aircooled model with a standard coil and points?
If it's an rz you need a new stator.

zeel installed

back again after a short leave of frustration.... with myself... and a small electrical issue

still have this issue.... i have had the stator tested by a stator rewind company and it checks out all correct... so i kind of think my issue is in the lighting circuit.. something isnt correct... it is draining the battery... when engine is running
when the bike has a fully charged battery all lights and horn work correctly when turned on individually... but if i turn lights on the horn stops... then with lights off and the horn going if i put the indicators on the horn works in sequence with the indicators.....

the bike has been sitting for a long time.. 6 - 7 months.... and started first kick after priming with fuel... any ideas fellas....

zeel is working correctly and powervalves are cycling correct... plug in display unit is showing all correct revs and ignition etc...

bike revs as per normal... but once battery is drained the bike will stop dead as the zeel requires 12 volts...

when lights etc... drawing a current.... you can see volts dropping with a multimeter on battery.... revving the bike doesnt show any increase in volts at battery

Two thoughts as sounds like unrelated issues, but is probably linked as you think....

1, Sounds like a bad earth if you get horn with indicators etc, ie its using the other item to get to earth. I would check all the wiring in the headlight area and clean up the connectors as well. Even if youve already done it... check for continuity on the earth as well, it could look fine but be broken inside.

2, The draining when running is strange. Is the regulator tested as ok and connected up right? you should be able to see the output from the stator and from the regulator, and if its working and power gets to the battery (measured across the terminals) then its the battery not taking the charge, but it sounds like somewhere along the line something is broken, a connector or a reg perhaps?

[aaronmvrider]

the bloody multimeter just shit itself... not a good start

Did you ever get to the bottom of this problem?
And if you did what was the cause?

[yamasukiman]

I've been having problems that are not to dissimilar to what you have.
I've checked stator resistances, rectifier/regulator on the bench and found no problem.
I do have spares so I substituted both stator and rectifier/regulator on the bike and still no result.
I started to suspect the regulator part of the rect/reg and started checking that we had continuity in the loom.
I found the red wire from the rect/reg plug didn't connect to the positive battery wire.
I discovered a break in the wire where it is spliced into the loom under the fuel tank.
With that sorted we now have a charging system that works.

I wonder if you might have a similar problem?
I was an Aircraft electrician a long time ago so I am a bit rusty with these things but I do get there eventually!!

correct... wiring issue
