Glad you got it fixed. Sorry about the fried TIPM, though.
Regarding some of the suggestions, above...
Disconnecting both battery leads doesn't make it any more disconnected than disconnecting only the negative.
In the link above, they tell you to disconnect the positive lead, and repeat the word positive. That is not a safe practice.
A good rule of thumb: Never apply a wrench to the positive terminal when the negative terminal is connected. Going by this rule will greatly reduce the risk of shorting your metal wrench on a ground point. Wrenches get hot real quick when shorting the battery, and the spark could cause the battery to explode.
