After the brakes, it was time to tackle cleaning the engine grounds. There are 4 of them that I am aware of:

Main ground strap:


Easily accessible, near the brake booster. Looks like I need to deal with the surface rust from where brake fluid ate the paint.

Multi-ground point:


Hiding directly under the brake booster. Complete pain to get at. Not convinced it's for the engine.

One beside the FPR:


And one below:


The first one also bolts to the head.

The second one I relocated, because it's dang hard to get at.

The third and forth both bolt to brackets which are in turn bolted to the head, so to ensure a clear path for the electricity you need to clean the brackets too. The wiring harness is in the way, and just happens to turn a fairly easy job in to a pain.

All connections were cleaned and coated with protectant, so they should be good for years to come.

And holy heck, what a difference! Smooth idle, restored power at low rpm, and no more hesitation/struggle when the alternator gets heavily loaded at slow idle. I can now cruise in town in 5th gear!

Why is it always something simple? And something you keep putting off?
