I tried a battery disconnect on the negative wire for a while and it ended up going bad. Not sure why it went bad? I took it out and just keep a 1/4" ratchet with a 10mm socket in the glove box. I quit using the cheap battery box cover and now it only takes 30 seconds to remove the entire negative post group. I've flat towed it about 6,000 miles with no problems. Need to add tail/brake lights now.
Green Mtn Boy, please add the pics of your install.
