I can only wish you good hunting with this one MJ.
I understand where you are at, but very interesting.
I think you are correct thinking that this is down to some amateur messing with something not properly understood.
I'd love to get my teeth into this with you. But then you don't need an old fogey peering over your shoulder.
Compliment time.
I've been looking all my life for a good looking young lady with mechanical and electrical skills along with a good sense of humour, don't bring your wedding dress to the Annual Meet I'd be tempted.
