Quick update on mk3 problems.
Got fed up with it not working so decided to tinker. Tools layed out and ready to go to war. What's the worst that can happen, shit or bust. removed battery casing and set about working out how everything came apart when i noticed the two little battery terminals were slightly corroded and looked like they had been pushed in to far. after a quick clean up and jiggle with terminals,new batteries and we're back in business. so glad i didn't right that collar off. just goes to show check the simple things first lads.
Cheers for the help with this and happy hunti
