Fixing Earthing Problems - Why and How

[John Vreede]

Yeah the different model sure are different.
A Uly has the battery turned 90deg and the rubber strap goes in the same direction as your hose clamp. The connections are on top and vibration doesn't loosen them.
Also the computer ground lug on a Uly has 2 wires crimped into the same lug, one fat wire and the other thinner, whereas all yours appear to be single wire per lug
The battery tray is actually just getting in the way of the grounding (Edit: Not so. The passive zinc or cadmium plating eases the corrosion potential - but it needs to be clean!) as they're all trying to make electrical contact into the aluminum. People need to clean&protect the joint in between the battery tray and the Al sub-frame
At 0.2 Ohm your lug connection is OK
BTW all your connections look to be dry, If you don't coat them with some protectant, then they'll degrade again.
Thx for the pics, its clear now.
Will put some measurements and pics in the checklist. - jv
