Upgrade Your Battery Cables

Electrical problems have punctuated the winter this year with the Big White Bus. I’ve had a lot of trouble electrically speaking. The engine has run rough for a few months now. The tachometer has been exhibiting the bouncing needle problem indicative of a failing alternator. A glowing battery charge light when the headlights are on. And of course as you read in the last post my ignition switch has been acting up.

I got the ignition switch problem sorted out and now it was time to upgrade the battery cables. And there is only one man you go to when it comes to electricity, The Evil German Dude. His evil liar has all the tools and he has a supreme understanding of the dark art of electricity.

Other than “replace the cables” there really wasn’t a clear and concise plan when we started to swap the original OEM battery cables for an upgraded set hand-crafted by the Evil German Dude. The plan is pretty simple:

  • Remove the old cables.
  • Build new comparable cables.
  • Install the new cables.

There are four battery cables of concern on this project. One goes from the positive battery post to the starter. One goes from the positive battery post to the alternator. One goes from the negative battery post to the frame. And the last is a fresh ground connection to the fender from the negative battery post.

We also upgraded the battery post connections to industrial grade. The ones they sell at the auto parts store are just…INADEQUATE.

EGD was able to salvage some heavy-duty battery cables from a private contact he has and we re-purposed them for use on the Range Rover. […]
