Motor removal

Ouch ! Unless you love to tinker, have plenty of room and tools and are just looking for a reason to do major work on the bike.

The Rocket is a relatively easy bike to work on if you're going that route, and you'll save a heap o' money if you do it yourself, though you didn't say.

Have you done the tests so beautifully outlined by @DEcosse so you're sure of the electrical behavior and most probable cause ?

Please keep us posted as you proceed.
 
I'll get to put it up on the operating table after work tomorrow, I'm going to watch how to do it on Discovery tonight. I'll be an expert then.... Right
