Thread: Attention All Puma Owners

Just got my auto leccie doing some work here today, so I asked him about this problem and these are his comments.

1. The most common reason a "different" earth circuit is completed is when the battery earth lead is loose, dirty or other poor connection, rather than other poor earthing. So it's critical to make sure that the battery connections are good and secure.

2. He sees more problems with arcing & pitting of positive battery terminals and connections.

I know that after I had the battery out at one stage, my scan gauge showed lower voltage. I'd tightened the terminals, but one not tight enough. I'll pay particular attention to this in the future & check on the scan gauge regularly.

Ok I have just got back from KLR having fitted a new handbrake cable and we had a really good look at the earthing system. Frankly its less than impressive.

There is one earth cable from the negative battery to the chassis to the engine, this cable has a T joiner where it attaches to the chassis and if you unbolt it the chassis is painted. The body is painted and then attached to the painted chassis so not very conductive, no surprise that the current didn't want to travel down this path!

We have put some additional earthing straps in between the chassis and transfer case and when I am back we will also earth the body to the transfer case.

LR may have addressed this starting with either MY12 oir MY13. In the front driver side wheel well my MY13 has an earth strap from the chassis to the footwell whilst my MY11 has an earth strap from the chassis that disappears up behind the guard... haven't checked any further though.

Looks like a couple of extra earth straps to be installed this weekend......

Better safe and a easy little job.

Sounds like an earth strap from a nut on the back of the handbrake mounting bracket down to the chassis would be a good way to go.
