help plz, no power to motors

[steel]

Hi

I have made the "basic rov control system" with joystick and the relays are clicking when i move the joystick but there isn’t any power to thrusters. What are I’m doing wrong? Any help is appreciated.

Regards steel

Did I buy wrong relay? Should be 2 NO and 2 NC

If i wire the motor to pin 1 and 2 or 5 and 6 with no joystick movement nothing happens. But when using joystick the motor is running.

Is this the right way to read the reley

1 and 2 NC
3 and 4 NO
5 and 6 COM
7 and 8 Coil

?

I think you're reading the relay right.
Here's a link for the Seafox wiring. The COM, NC and NO are different on these relays, but you should be able adapt it to your relay.

This is how yours should be wired. (forgive the crude drawing)

(edit - Just to be clear you need two relays per motor to control forward and reverse.)
