Loooks like you owe one to Siemens for making a faulty Over-Voltage-Relay.

Behind the battery, aluminum relay. Part 000 540 52 45.
Change it to 000 540 67 45 .

...about $60 , can get it right here.

And, of course, if that fixes it...go give her some more $$$$...

I often wonder how many get traded/sold BC of a bad OVP?????
