Power to electric fan, but it's not switching on...
Hi, I hope someone with greater electrical understanding than me can help out?
I have a dial adjustable thermo switch that feeds to a relay then on to the electric fan.
This seems to be working and I can hear the click at the relay, but the fan doesn't switch on.
There is 11.7V measured at the connector between the relay and the fan. I can rotate the thermo switch to cycle between 0V and 11.7V. The "connector" is just a pair of regular spade terminals for power and earth.
If I run wires straight off a battery to the connector at the fan, the fan starts working...
Seems to me like I've verified power to the connector, and power from the connector, and the spade terminals seem clean and undamaged, so I'd appreciate any thoughts on how I can fix this.
Thanks!
