Does battery cables need to be disconnected when changing headlight? sorry if this came up already


Technically, no as long as there isn't any power going to the headlamps there is not need to disconnect the battery cable. BUT any operator's manual will tell you ALWAYS disconnect the positive cable from the battery (or disconnect power source) when doing any sort of work on anything that has power, because you never know. If you remove the negative - you risk still grounding to the chassis if you place the cable loosely inside the engine compartment.

Tighten the bolts to 40 ft. lbs. (54 Nm).
  2. Attach the electrical harness connectors to the starter.
  3. Connect the negative battery cable and check the starter for proper operation.

I have an electrical problem. When unhook my negative clamp form battery i can get 12 volts from my negative post to a body ground. So I have a short somewhere. Where would it be.


IF YOU UNHOOK THE NEGATIVE CLAMP FROM THE BATTERY AND YOU STILL GET A READING FROM NEGATIVE POST ON THE BATTERY TO THE FRAME YOUR METER IS COMPLETING THE 12 VOLT CIRCUIT AND THAT IS WHY YOUR READING 12 VOLTS ON YOUR METER. SOME BATTERY CABLES HAVE A SECOND GROUND FROM THE CABLE TO THE FRAME BUT IS CONNECTED AT THE BATTERY POST SUCH AS A FUSEABLE LINK WHEN YOU DISCONNECT THE CABLE YOU DISCONNECT THE GROUND. IF YOU HAD A SHORT AND READ 12 VOLTS THRU THE GROUND YOU WOULD DEFINETLY SEE SMOKE
