With regard to contact cleaners, the one used by electronics professionals is called Deoxit. It is more than a simple solvent as it chemically removes oxidation. Fairly expensive stuff.
Must confess when I found a few green terminals on a some connectors I very carefully used the files to clean the pins , along with using the spray , they came up a treat and tested them after with a multimeter to ensure Vdc was going through the...
That sounds amazing mate, and i will definitely be listening to all your advice. You obviously have a wealth of knowledge about these that is invaluable to novices like me. I'm very intrested and keen to learn all i can Graculus.
It's the connections in the plug housing that will be problematic - watch out for a poor fitting battery box cover (or missing foam tape) that's the usual cause of water ingress - and a poorly fitted E-box cover!
I had two Disco 3's from new, the...
They're all solvent based, of one sort or another. There isn't a solvent for copper corrosion...
The temptation is to use something abrasive, but that just widens the receptacle or thins down the pin. I've never found a better solution than...
I cleaned the connections up a little and examined them under an electronic microscope and all looks fine. I do have an iCarsoft LR2 which i plugged in initially a few days ago but i didnt reallt understand what i was looking at, i do remember...
The 'TCM' you've found is actually the Transfer Case Control Module - the 'true' TCM is integrated into the gearbox itself. It's possible its the transfer box that's throwing the transmission fault on the dash. Try putting the transmission into...
I don't think there's a start inhibit - otherwise the starter wouldn't click. If the initial checks are OK, then you need some way of reading the DTC's ('fault codes') to progress the diagnosis.
I've seen that message on other brands and later...
I removed the battery and took the TCM module out, i took the TCM apart looking for any signs of corrosion but it looks ok, however there was some slight green discoluration on some of the plug pins. Im going to spray some contact cleaner on them...
First thing is to check the engine ground strap - easiest way is to use a heavy jump lead between the battery negative post & a good, clean bit of engine. I think the transmission fault message is a 'consequential' fault, not the cause of the...
