Let's get the obvious out the way first.check the main fuses.then check the new battery "is"charged,sometimes the come dry charged,this means no acid in cells.check that.then using an indicator bulb or similar connect direct to battery and see if it lights up.then check all battery terminal connections for clean bright metal to wire.while Im at it use the indicator bulb again on the old battery to check that.after this it gets complicated.
