August 29, 201411 yr Messing about in the garage yesterday , I decided to take the shroud off the bottom of the engine. ( Forester 2010 D ). There are two braided ground straps left & right side of engine . One of these had completely corroded away . After reading how important these are and the effects the electrical circuit I replaced it with a much stronger copper cable .Wonder why there so flimsy and I guess are only replaced when things go wrong.
August 29, 201411 yr yep, yep, costs; as copper is more expensive then metal in most cars these braided ground straps are way to small and putting more strain on the battery. it's a good mod to change them for thicker and better ones
August 29, 201411 yr Many electrical problems on older cars can be traced back to a bad earth. I have a home made earthing kit on my GT-B and it has improved things greatly. Everything from radio reception to steering feel is better (the GT-B has electric speed sensitive power steering).
August 29, 201411 yr Hi adam, ro you have any pictures of where you've run the grounds, I've been looking at doing a diy job too as the earthing kits are extortionate and I could do jsut as good a job
August 29, 201411 yr No photos to hand, but from memory I ran a cable direct to the battery from each of the following... 1 cable per cylinder head (the GT-B has coil on plug ignition). Inlet manifold. 1 cable per suspension tower using the same connection points as various OEM earth cables. I'm sure there were six but I can't remember the other one at the moment!
September 4, 201411 yr Cheers for info, hunt round the internet found one for a reasonable price, I'd have had to factor into the price of a diy build a soldering iron as mine has seen better days so it worked out the same price :-D
