What would be the symtoms for voltage regulator rectifier going bad or stator going bad :shock:

A bad stator usually has either no power output,very low power or can become thermal....
The reg/rect module can show the same....
If the battery voltage is above 14.5 volts DC at 3000 rpm....it's a wiring modification.

If the voltage/charge is low or high...it's a process of elimination...
There are 2 components to the entire charging system...
The stator should put out power with rpm...
The R/R module converts the 3 phase AC from the stator to a stable,regulated DC voltage...
Should there be ANY corrosion in any plug or ground of the system...it will affect it....

Normal specs for the bike....
Measured directly at the battery posts...
12.8 engine off
12.4 key on
11.5 cranking
12.5 low idle..< 900 rpm
12.9 and climbing as the engine rpm increases
holding 3000 rpm
12 amp charging the battery...tapering off to 3-4 amp after 10 minutes.
Clamp on AC amp meter shows 7-8 amp on each "yellow wire" at 3000 rpm....The stator output.
13.5-14.3 volts as the rpm changes from 1000 rpm to 3500 rpm.
Voltage should not increase above 14.5 volts ..
There are specific tests for each part to determine what may be wrong...

Where do you want to start and what's wrong..??

Check the connector with the three yellow wires from the stator next to the front of the battery is it..melted/black/burned?? If so cut it out and solder wires back together or add new connectors spade type not in a single connector..helps dissipate the heat.

The above all excellent info.

I am having a similar problem on my 82 interstate. I replaced the Regulator Rectifier with a brand new aftermarket one. Ran rough once the bike got warm. In the past I had a problem with a vacuum valve sticking, I removed the vaccuum line from the carbs and sucked on it a bit to unstick the valve, ran fine after that. I restarted the bike while it was still warm, it ran perfect but the Alternator/Battery tester that i had plugged into the cigarette lighter was showing that the alternator was putting out over 15v now at low idle. the lights were flickering slightly at idle but nothing extreme. I shut off the bike and tried to restart it again, now i have absolutly no power. No neutral light, headlights, oil light...nothing.. I am almost 100% sure that the stator is good as its putting out the voltages stated earlier in this post.. any ideals?

Check the main fuse and all the big connections and wires around the battery, solenoid etc. sounds like you burned something up.

Forgot to metion that usually if i let it sit for a little while i get power back and everything works like it should for a while

Yes on the 30 amp dog bone fuse.
Check the fluid level in the battery.
At 15 volts,it has a tendancy to boil dry.Load test the battery.
Your going to have to look at that overcharging problem too.
The charge voltage should not exceed 14.4 volts at 3500 rpm.

It's a brand new battery and I did a measured discharge at college with a aircraft grade discharger/analyzer everything came back good. The overcharging problem only occurs after the bike is warmed up and running for a while. It's at a point where i could ride it if I absolutly had to but I don't want to burn anything up. The voltage regulator is brand new out of the box with only about 20 minutes of run time on it. when the bike is running but not when its overcharging the battery is around 14.4-14.5v

I would do as Virgil mentioned, especially the part about the battery, I know my overcharging regulator on my 1100 boiled the electrolyte out of my battery, and it then wouldn't start the bike.

Check the sense wire going to the regulator. The regulator uses this wire to determine what the system bus voltage is. If it sees low voltage on that wire, it boosts its output to compensate. If that wire has a bad connection somewhere, or is just otherwise deteriorating, and is showing less volts on it than you see at the battery terminal, the end result is that the regulator will inappropriately boost output, causing too high a charge voltage.

I ended up running a fused wire directly from the battery, through a relay, and connecting that to the sense wire on the regulator. I then took the original sense wire and used it to trigger the coil on the relay. That way when the key was turned on, the relay turned on, which connected the battery directly to the sense wire on the regulator, giving it an accurate picture of the battery charge. That solved my overcharging problem.

I tried the three yellow wires and was getting 7to8 but here is what i see as i drive the bike the first three gears my amp meter on the dash reads 12 to 13 its when i go either 4th gear or over 40 mph it drops to 8 any thoughts on that

Yes...You might have a bad ground on your volt meter.
I don't assume they work.Attach a DVM directly to the battery posts for your tests.
