Update------ I've done all that was recomended by our pals
--- all checked & o.k.// and guess what--
The bugger would not take a charge through the optimate Grrrr.
It turned out that the initial prob' was that the fuse on the optimate had blown
Well I never even thought of that in the 1st place,so each time I was piddlin' around & pestering you guys, then re-plugging in to the charger----
feck-all was happening
Agrrrrr.
Anyways, I'm glad that at least you fellas have helped me to get things as they are supposed to be----
Looks like I owe yer all a drink------ DON'T GET OLD !!!!
