The smart charge will make the lights flicker slightly every now and then, normally when it's ticking over, you will see it flick very slightly 4-5 times. On the ST170, if the dash lights flicker, turn the brightness down slightly, that will stop it.
But the OP seems to be having more serious flickering so it must be something else!
