GY6: Unregulated AC on DC Charge Circuit - 2 Diff Rectifiers By viceroy (Read 1,103 times)

[viceroy]

I have a 2013 Taotao EVO 150 that all of a sudden wants to do nothing but send unregulated AC power out of the rectifier, instead of regulated DC power.



My first warning that something was going on was when my battery started dying. Eventually, my gauge cluster lights, DRL's, turn signals, and brake light (DC power) all went out completely.



With the scooter still running, I disconnected the battery and found that it had a pretty good charge (12.4V), but the fuse between the battery and the scooter was no longer allowing power to pass through it. The filament was not burned out, but it was not conducting very well.



Upon disconnecting the battery, all of a sudden, the DC powered lights went really bright, and were doing that subtle pulsing thing that the AC powered lights do. I revved the engine a little, and they all burned out, except for the gauge cluster lights.



I figured the rectifier was toast, so I threw in a spare one that I have. Result? Same thing. When I connected my test light to the red DC output wire, it glows bright enough to scare the sun.



Anybody have any idea why two separate rectifiers would both pump out unregulated AC power instead of DC? Real head-scratcher on my part.



Thanks in advance.

Both rectifiers may be bad,,,

[jct842]

Don't have time to look it up here in the library but if you do some reading there are procedures for checking the stator and regulators.

[viceroy]

Been there, and done that. Zero information on my specific situation. Guess I'll just have to try yet another rectifier.

The second one I tried was working 100% on my other scooter until the moment I removed it. Don't think it's terribly likely that it is bad.

[cyborg]

Well if you know it's sound ,, then check all the grounds around ,, electricity gets weird if grounds are not hooked up or are intermittent

[viceroy]

Will do. I'll check continuity through all of the grounds and check back.

[tvnacman]

see if you getting battery voltage at the stator wires key on an off. with the regulator disconnected.

[viceroy]

No battery voltage at the stator wires. The only reasonable conclusion I can make is that the stator must have gone bad somehow. Only reason why now 3 separate regulators would not work.

All grounds are verified perfect.

I've ordered an 11-pole conversion with harness and regulator.

i just bought a new engin for my 150cc jonway scooter an im running a AC charging system an my engin is Dc so wat do i need to do to fix this problem i cant send the engin back is there away to change the some of the parts on the engin or use my old cdi an reg will that help i had no idea it was DC i just found out im running this AC system it keep blowing the bulbs in my head lights a guage i put the cdi that came from the engin an everything blow but the blinkers an the brake lights

Start a new thread, include year make and any info you have. pictures of the regulators and the harness.

Hello I do know a Lil something about DC stators. Well the old Honda 3wheeler's had DC and yamaha banshee which I have ,all we do to convert them to AC is float the ground connected to stator. So to me if all of a sudden u running DC when it should be AC power then u mite be grounded somewhere. Check stator then work your way up .
