My scooter is an AC system.
For reasons i don't get, that seems to cause problems even when the engine is off.
Example: I have an LED strip to augment the tail light. It flickers, even with engine off.
Example: have an LED running light inside the headlight I use during the day to save juice. Often have to turn it on and off after getting the scooter started because, otherwise, it doesn't always turn on even though powered (might be the flasher unit upstream of the LED itself).
Example: I have a pair of radios (1 front, 1 back). When I accelerate they often momentarily cut out, though obviously still are powered. I even installed a relay so the power will come directly from the battery - didn't solve the issue.
Any idea, you electronics gurus, why this might be the case? Regulator feeding something back even with the engine off? Stator maybe?

For LESs, you may need to install a resistor, they don't draw enough current to top the required threshold.
For stereos, you may need a small capacitor, check with a local automotive stereo installation a shop.

Where are you getting the power for those lights? Straight from the battery or did you tap into something else? Do you have to turn the key on to power the leds?

The LED strip for the tail light is spliced into the tail light circuit. The radio is straight from the battery, via a relay activated by ignition.
The fact the tail light flickers even wiht the engine OFF is perplexing.

Well the taillights( running lights ) are DC straight from the battery and will come on with the KEY ON. Usually if they Flicker it is usually a bad ground at the socket and or the BROWN live wire is not making good contact with the BULBs socket. The sockets on these are very cheaply made I had my trikes taillights flicker and I had to fix one of the sockets the Brown 12v wire was loose.
To verify if that is the case just wiggle the wires by the tail light socket.

The fact the tail light flickers even wiht the engine OFF is perplexing. rcq first Ill address the light strip.... If it's spliced into the tailight circuit, when the LED strip blinks/flickers, does the tail light also flicker? If they both flicker with the key off, it may be the case you have a faulty key switch (or bad connection like Alley suggest) ... If it's only the LED strip, it's possible that the device has capacitors that store a little bit of energy and what you see as a flicker is actually the caps discharging... -------------------------- The Radio.... Relays are activated by a specified voltage... Give it too many volts, it cuts out, to few, it cuts out..... What you're describing sounds like your regulator isn't doing it's job... When you go up in RPM's you increase the current, your R/R is designed to do 2 things, take that A/C current and convert it to usable DC, this is rectifier part, the other part takes that usable DC and regulates it, hence the regulator part... R/R... If the regulator isn't properly doing it's job, it will allow the voltage to spike or drop... Seeing as how your radio is dropping out when you increase RPM's that indicates when your stator starts pumping out juice, the regulator let's it and I suspect your voltage curve may be increasing with your RPM's, exceeding the relays tolerances, then shutting it off until the voltage comes back within tolerance. I suggest installing a volt meter, go driving and monitor your voltage. These kind of gremlins are very hard to diagnose without the scooter |
