Batteries...
I have presumed that the chugga, chugga, chugga was the gears for the starter motor failing tomesh with the flywheel due to lack of juice from dem dere battreries... Swapped Tonkas over into MUX & off he went, happy as a sandman

Much to my releif!!!
Got everything swapped back over & put MUX's 'pacemakers' on charge - woke up around 5.45 this morning, couldn't sleep so had them back in by 6.30am. Had to wait til after 7am to check though as he's a bit throaty at the moment... All good though
Will be getting a set of spares for the starter though as a bit of PM & maybe its time for a new set of duracells for the big boy. New thread for discussion coming right up ;-)
Ade, thanks for the offer of the tirfor dude - I suspect we would have moved the house nearer the road though ;-)
Jim, nice to see you & REX. Thank Rob & family for the parking spot outside their house again if you speak to them ;-)
Adios
Hang on, almost forgot the sting in the tail...
Tonka (our T reg Colorado) is the wife's DD & I don't get to drive him too often. Driving to work yesterday, I thought he was a bit clonkier than usual so when I got home before stripping out the batteries, I had a rev about & gander under the bonnet - now't really to see. Afterwards, when the batteries went back in, I had a proper look as hes was right rattly. Grabbed the end of the zorts pipe, rattling stopped - cool... And then it fell off in my hand!!! Rear section out of the big centre box!!!
So thats both of the bad boys in need of exhausts... Another thread coming up for that ;-)
