Thanks for asking that Mike
You helped me out.
I've been working on an electronics project related to the
starter circuit and got stuck at the last fence.
your question nudged my brain back into gear and
I realised I hadnt fully considered what was going on in there
DOH!!
I cant believe I'd overlooked that, most embarrasing.
Anyway
After I stop kicking myself in the ass I can move on
and finish it.
