Had a walk out with my dog blade last night , this was only the second time I've used it .I know that the wire issue I totally stripped it down resoled it and added a little mod to it but my problem is that when I turn it on it's ok after 20 -30 seconds it starts pulsing it's not that big a problem I only paid 25 sheets for it , I'm wondering if the battery is to big I've tried two 12v 6.5 amp and 12v 8.5 amp I'm hoping to try a 4 amp To see if that helps so if anyone has any ideas please let me know atb mark ps still got 16
