Hello my bike is gas gas ec 300 2010 without battery, i want to install a standard cooling fan , i have RECTIFIER AC/DC with yellow wires , white wires
red , black .Can you help me how cu connected the wires ?
There should be a diagram from the part manufacturer.
My guess would be:
Rectifer yellow to stator yellow (OR stator white for slightly higher voltage)
Rectifier white to engine/chassis ground
Rectifier black to minus side of fan
Rectifier red to plus side of fan (fan runs when engine runs)
Alternate hookup:
Rectifier red to thermoswitch, other side of thermoswitch to plus side of fan
One other thing to note is that your DC minus (black wire) should NOT be grounded to the engine/chassis. The DC power must be isolated from your stock AC wiring.
