OK, i checked the connections, yesterday, sprayed them with WD40, all was good yesterday.
Today, just as i arrived in town, it stopped working.
I pulled the right brake connections apart and hey presto, it's working. Put the connectors back together, and it stopped again, so this time i put some pressure on the lever, to open it, and the motor stated, so that seams to be the issue.
I'll see how i get along for a few days, if i can live with it i will; if not i'll get another lever.
So mystery solved. So i'm happy.
Not so impressed that the shop did not figure it out for the past 6 months.
Thanks one and all.
