yep, the main power fuse broke right in half, had to order a new one.  this time i also ordered a contractor to be the main on/off switch and i'll use the main power switch as an emergency power off 'panic button'.

i also decided to run the bike at 48 volts instead of 72 volts.  at 72 volts with 6 batteries the bikes handeling is a little on the unsafe side.  so instead of getting 55 mph for 60 miles i should get 48 mph for 45 miles.
