Kenscomet Posted September 24, 2018 Author Report Share Posted September 24, 2018 I disconnect the positive cable instead of the negative because the negative is under the couling could this be why I get that code but it's not all the time Quote Link to comment Share on other sites More sharing options...
TheWizard Posted September 24, 2018 Report Share Posted September 24, 2018 It makes no difference electrically whether you disconnect the positive or negative cable. Both are necessary for current to flow. The reason for disconnecting the negative is for safety... if you happen to bang your wrench against something metal while disconnecting the negative cable, nothing will happen. But if you happen to bang your wrench against something metal while disconnecting the positive cable (while the negative is still connected) you would create a massive and very dangerous short circuit. 1 Quote Link to comment Share on other sites More sharing options...
