Alright, who can explain this electrical monstrosity? By FACE PLANT FOR LIFE (Read 441 times)

[FACE PLANT FOR LIFE]

Alright guys, I've got a 50cc GY6 that runs great, and is, in general great! Has no electrical gremlins to my eye, except for one that I can't quite put into words..here..just take a look:



I replaced the voltage regulator, looks to be the same problem

The bike honestly performs fine, but I CANT figure out why its doing this...The multimeter comes within 6 inches of the battery and the thing SPAZZES. If I touch just the ground probe to the battery, it SPAZZES, and if you touch just the positive probe to the battery, it doesn't...so..any idea?

Put the probes together and it probably won"t do that. It is picking up impulses from the scooter quite possibly from the spark plug. There is no load on the open probes. An engine hour/rpm meter works on the same principle. That you wind one insulated wire around the plug wire and it picks up a signal to indicate rpms.

I'm thinking lack of shielding.

Does it do it if you take pull the connectors off the meter, they are dangling and both touching ground.

my ipod will do strange things also. i think it has to do with the electromagnetic field generated from the stator causing interference but i'm not an electrical engineer so i can't be sure.

[Alleyoop]

That is the most likely scenario the stator causing interference

Probably what it is, just like if a car doesn't have non-interferance sparkplug wires, you can hear engine pulses through the radio.
