Hi. A friend of mine has an remote controlled garage door. It has a 4 lead 350W AC motor. It has 2 relays to control the rotation direction of the motor
The wires connections are as follows:
1. Green/Yellow => Ground
2. Gray => 240v through a 4a fuse and a transparent control relay
3. Brown => off position of the white relay which takes power from the transparent
4. Black => on position of the white relay
It also has an AC capacitor that supposed to be connected to the motor (parallel or series, i have no idea).
A few years back the capacitor blew up (he doesn't remember it's capacitance but he thinks it was about 12uf) and my friend replaced it with 16uf (was that a mistake?) it worked ok until yesterday when the capacitor , the 4a fuse and the pcb traces from the relays to the motor connectors blew up. He disconnected the capacitor which was rated for 250v (too little tolerance isn't it?) I bought him a 450v one but now i don't know how to connect it...
Can you shed some light on this?
Best regards and thanks in advance!
