I bought this PWM with display and switch off eBay.
Tried to test it out by wiring up to battery and pump but no joy.
Followed wiring diagram (battery to pwm, pwm to pump) led display lights up, green push switch turns this on and off fine, dial works as "flow rate" moves up and down between 0-100. But pump not being activated.
Checked pump wasn't faulty by connecting straight to battery, that's working fine.
I'm at a loss... any one know what's up?
