need4speed Posted January 24, 2014 Share Posted January 24, 2014 After finding out from a friend today where to earth my lambda sensor, it occured to me that i dont have ANY of the earth points connected on my defender. This is due to a loooooong-running ground up rebuild... So as title suggests, if someone could let me know where all the major earth points should be, id be very grateful. Will the fact that i have a galv chassis affect anything chassis-wise? Quote Link to comment Share on other sites More sharing options...
Lewis Posted January 24, 2014 Share Posted January 24, 2014 There is a braided earth strap from gearbox to chassis on my 90, and then a 35mm2 cable from tubular outrigger to battery. There may be a second earth strap from engine to chassis but I can't remember without looking at it. If I were starting from scratch, as you are, I would run 50mm2 from batt negative to starter motor bolt or convenient bell housing bolt, then a 35mn2 cable from batt negative to chassis bolt, and a 16mm2 or 20mm2 cable to a fixing on the bulkhead as some loom earths fix to the bulkhead. Also I would run 4mm2 cable from batt negative to the earth studs on both wings so that the headlights have a decent earth path Quote Link to comment Share on other sites More sharing options...
HampshireHog Posted January 25, 2014 Share Posted January 25, 2014 Fully agree with Lewis . after buying my 90 I had shed loads of leccy faults , dim lights , even dimmer when you asked the heater blower to have a go at its job to demist the screen , but after fitting a recon gearbox I ran earth straps back to the bell housing , the chassis rail and on into the engine compartment up to the bulkhead , Christ what a difference , the more the merrier Quote Link to comment Share on other sites More sharing options...
