I added some LED light strips to my BMS Heritage 150cc splicing into the wires at the tail light. One is for running lights and the other for brakes. Around that same time I noticed that my voltage meter on the instrument cluster was running high. But I don't know if it was high before I added the LED's.
Now I'm concerned there is a real problem because my headlight bulb blew. I replaced the bulb then disconnected the LED's but the voltage is still running high. I reconnected the LED's and still high. No difference really with the LED's connected or not.
I suspect a bad voltage regulator because of these readings at the battery:
My question is; does the video indeed conclude that the voltage regulator is bad and did the LED's create the problem or were they just a coincidence?
Thanks for any incite.
Bill

Reg question I don't know. If u r worried about the draw of power, change the running light/ brake light to an Led also. Parts for scooters has them. That should more than free up power distribution. LED's draw far less power. Bright lights save lifes.

it does sound like your voltage regulator could be bad, thats usually one of the biggest problems when they go bad, is high voltage, sometimes is low voltage too but most of the times is high voltage and blown headlights because of the high voltage.

Thats too high voltage . what happens when you use the turn signals and brake lights . I don't mind the voltage 15vdc or a spike from time to time to 16vdc , 17 or 18 is too high . Can I see the style regulator your using .

I didn't video voltage with the break light on but I did notice that the scooters' meter was a little less with the breaks on, but again, I don't know by how much. And so I don't have to go through all the hassle of do the photobucket thing, here is a link to my voltage regulator on ebay. Here |

I have a slightly different 6 pin regulator that you can use a sub . Looks like the same mounting .

If you have high voltage you voltage regulator is not doing its job. Its responsible for keeping electricity on the bike regulated, hence its name. Its possible that you wired something wrong or created a short during the led installation, but assuming you knew what you were doing this is probably not likely. You should have ran a separate line directly to the battery for the leds. The wire harnesses are made with paper thin wires and tend to fail. I would check for a possible short anywhere, or loose connections then I would assume the voltage regulator. Their often under 10 bucks and are extremely easy to change. It should be located in the front of the scooter behind the body mounted to the frame. Simply unplug it, unscrew it and replace. Running at the voltage will damage your battery.

The wiring was too easy to screw up, so I highly doubt that's the issue. And if there's a short somewhere the bike either came that way or it happened within the 311 miles that I drove it so far. I got a new regulator on the way and am counting on the problem just being a bug in a new machine. It was suggested that I run a wire from one of the regulators' mounting bolts directly to the negative battery post and I see no harm in that so it will be done. And I am going to take a new reading immediately after installing the new regulator and then go from there. And, until I get the problem resolved, Betsy Mae is gonna sit.  |

On the plug to the regulator , be sure the black wire is 12v when the key is in the run position . The black wire senses regulator output voltage then internally adjudts .

Turned on the key, but didn't start the engine. 12.0 volts exactly at the black wire.

The black wire ckt is bad internally in the regulator .

So do they go bad, just cuz, or could there be a reason for it's early demise?

Some people have good luck and they never go on the bikes, some don't. I've had my headlights blow out back to back, but only at mid-high, changed the regulator and have been fine ever since.

A regulator is basically a shunt, it sends extra power to ground. The thing most don't understand is that shunting power to ground doesn't just make it vanish, power either has to be used or stored. The way a regulator uses this power up is by generating heat. This excess heat, together with manufacturing flaws, can cause it to fail.
