FAN KIT FOR EC300 question

Hi all
Wanting to install fan on my gg. But it's not original kit. So i wondering what "voltage rectificator from AC to DC" is for, and can i install fan without it?

The fan is then most likely a DC fan. What model of bike do you have? Only the last models have DC system. If you have any older bike you must install the rectifier since it has an AC system..

That rectifier should be an easy install. The black and red are your DC output to the fan. The yellow and white wires are for AC. You need to locate the yellow wire that comes out of your stator and connect into that circuit with the yellow wire on your rectifier. The white wire on the rectifier is then grounded to complete the circuit. The fan will run whenever the engine runs.

In the kit there is a thermoswitch you can add to the circuit. Put it in series with the white wire. This will let the thermoswitch ground the rectifier to create your DC for the fan. This is the way the kit is intended to be used so the fan engages only when the coolant reaches the temperature limit.

On the AC input it does not matter if you hook up the wires opposite (connect the white and ground the yellow).
 
I fitted a handlebar switch (the same as the map switch) and turn it on when the going gets tough or v slow

With the fan fitted (but not turned on) the bike will boil easier as the fan cowling will reduce natural airflow so once fitted remember to use it
 
Thanks all, but i don't understand - should i install rectifier with fan, or i can install it without rectifier?
 
Another thing to consider: Even if you have a battery, using the separate rectifier will put the fan load on your AC windings. This will prevent the fan load from running down your battery.
 
Hi, I have a 2011 EC300 E (electric start) and I'm planning to install a fan and I think is a good idea to have a DC source parallel to the original sistem so the fan will not drain the battery, that is possible?
 
Yes, just hook up the rectifier input to the AC wiring (yellow plus chassis ground). Connect the rectifier output only to your fan through a switch. If you use a thermoswitch make sure it has two connection terminals so that your circuit will be isolated from ground.
 
Add Fan Question

This is kind of a dumb question but I want to to mount a fan on my 84 RM 250. I am going to use a Spal Fan with a switch. This is the stator before restoration. My stator only has the two AC wires. Do I need a new stator with dedicated power source wires? Like in the video below,
