MAGNETO COIL for 48cc 66cc 80cc Motorized Bicycle
Magneto Wire Loop Set, for 2 stroke Motorized Bicycle Engines.
Goes around magneto magnet flywheel with four bolts,creates electrical spark.
Use silicone to seal off wires, enclosure and plastic bushing opening
from water after installation.
Does not have white wire, the white wire does not put out much voltage and is not used often.
Some manufacturers have discontinued the white wire.
The newer style magneto comes with only two wires,
a black and a blue.
This newer generation of magneto has the white wire
omitted with the black wire soldered to the core.
The core has been epoxied to help reduce fatigue
to the ground wire and also has a jumper wire to ground.
Additionally, the frames appears to be of better quality as well.
Testing this two wire magneto is really simple with the
use of an ohm meter. Specs and testing are as follows:
Ohm meter set to ohms. Red (+) on the blue magneto wire / Black (-)
on the magneto black wire. Reading should be around 325 ohms.
If you switch wires the reading should be the same.
With your ohm meter still set to ohms, put the
Red (+) on the magneto black wire and the Black (-)
to your motor case or magneto frame.
The reading should be 0.3 which means you have a good contact ground.
If your magneto meets these specs then you have a good magneto.
