The crazy thing is that the 10 amp auto fuse costs $1.25 each at my local hardware.  The difficulty is that the fuses are deeply deeply buried.  If you are an idiot like me and blew the fuse yourself you may want to look at some of the posts on integrated fuses and how to change them.  Rad doesn?t offer the service!!  So if you stuck a key into the port they want $750 Cdn to replace the battery.  It took me about 90 minute do it myself once I had the tools.  I don?t really have good skills.   

I may open my own repair shop.  I figure I could do about fifteen a day.m someone should.

Thanks everyone very much.   Took about 90 minutes once I had all of the tools. 
The 10 amp automotive fuses cost $5.49 for five
The R10 torx bit was harder.  A one inch bit didn?t work.  I found a two inch on Amazon.

My pictures show the placement of the fuse.   It is upper left.   But on top!
Moving the battery pack out was a bit tricky.  I ended up using a piece of wood and a hammer.
