Hi first thing to do is test THE BATTERIES WITH A LOAD TESTER. This will give u an accurate reading on the condition of the batteries cost E/BAY Aprox $35 .also check the reset switch it might have tripped open push it in .Cheers
Hi check Tyre pressure 30 to 35 Tighten CENTRE axle nut really tight.If this doesn't work loosen axle nut jack it up tighten axle nut when it's back on the ground tighten nut again ..this usually works ...cheers
Have you made sure the connectors to the batteries a fully clicked in? I had similar problem with mine, the casing had caught on one & moved one battery terminal clamp, this was after me going over a pot hole. Hope this helps
