Disconnecting Batter

I know this is a dumb question, but I searched on the site and didnt find exactly (its a very dumb question): When disconnecting my battery, after a URD TCAI is installed, do you just unplug the Red or Black, or both or does it matter??? (Jokes can be made at my expense haha) Thanks.

 

If your trying to reset the comp, you should disconnect both but ALWAYS disconnect the black (negative) first, that way if you touch something with the wrench on the red (positive) you won't get a spark that could blow up the batt (very bad) reconnect in reverse order red first black last

 

Sparky has given you good advice. I would recommend cleaning the post and terminals while you have them disconnected. If you have any more battery questions, please see the Car and Deep Cycle Battery FAQ on www.batteryfaq.org.

 

Thanks for the help
