Hello, I have a similar problem with my beta rev 3, fan stopped working. tried bridging the thermostat wires and nothing. So I put 12v directly to fan and nothing so figured the fan was goosed. Ordered new fan tested with 12v before I put it in and it worked a treat. Installed on the bike and it doesn't work. Tried riding the thermostat wires and nothing.
Tested the wires going from the thermostat thinking they may be broken but they are fine. Can anyone please help me to figure this out?
