Rubce Posted August 9, 2013 Share Posted August 9, 2013 Hi AllAm I correct in thinking there should be an earth strap attached to the engine in the bellhousing area? If so, where does the other end attach to?ThanksBruce Quote Link to comment Share on other sites More sharing options...
garyf Posted August 9, 2013 Share Posted August 9, 2013 There is an Earth strap off one of the lower timing cover bolts to the chassis on the Vitesse, so I suspect the Gt6 will be similar?RegardsGary Quote Link to comment Share on other sites More sharing options...
WIMPUS Posted August 9, 2013 Share Posted August 9, 2013 On my Spitfire there is a cable running from one of the gearbox bolts to the bulkhead (where there are more ground wires) and then to the battery .. :) Quote Link to comment Share on other sites More sharing options...
CHRIS211083 Posted August 9, 2013 Share Posted August 9, 2013 Should go from bell housing bolt on left side to left hand suspention turret. you could go to the battery neg if you wanted. I bought a cheap universal grounding boy racer kit for my spitfire and wired it to the earths of major electrical parts and earthing mounting points back to the battery. after that everything worked so much better. Even the window wipers were faster and stronger. Only cost £15. Bargain.Chris. Quote Link to comment Share on other sites More sharing options...
Paudman Posted August 9, 2013 Share Posted August 9, 2013 I used a late Spitfire one on my Mk1; it runs from the engine to the bulkhead but then continues right along to the battery earth. To be sure.... Quote Link to comment Share on other sites More sharing options...
rotoflex Posted August 9, 2013 Share Posted August 9, 2013 On my 1972 GT6 Mk3, the ground (-) cable goes from the battery, grounds via a clamp thing to a hole in one of the buttresses of the battery box, passes behind the battery box buttresses, a clamp thing in the center is attached at one of the gearbox bellhousing-to-engine bolts, & the clamp thing at the end is attached via a short bolt to a hole in the back of the cylinder head.http://www.canleyclassics.com/?xhtml=xhtml/diagram/gt6mkiiibatteryandleads.html&xhtmlcatalogue=xhtml/catalogue/gt6mkiii.html&category=electricalequipment&xsl=diagram.xslThe picture below is from the initiation of the successful college kid engine rebuild in 1979 after 3 years of having the car. Original battery cable, new terminal end, steel coolant pipe already superseded by a length of heater hose, a new battery box already & that one on its way out, who knows how many master cylinder rebuids &/or replacements but something recent evidenced by their shininess, evap canister mounted on the shelf as I remembered it always being so, overdrive added & wiring made of zip cord, the firewall as I don't ever recall having been so stripped of paint, & a light dusting of sawdust from other projects carried on in the family garage. The two blocked holes below right of the battery box were where the hoses from the dealer-installed original air conditioning entered the passenger compartment. Things sure got better from here!The valve cover & cap are incorrect for the year. This was a used engine that went poof put in by the BL/JRT dealership after their rebuild of the original engine went poof after about a year. It seemed like every time it went in for service at the dealership, it came out a little more beat up.Look! You can see the ribbed triangular air flap at the center! I still have it!

I still have it!Seems to be sort of the same way as mine at the battery box , just on mine it's on a bell housing bolt & i also still got that rubber original flap ;) Quote Link to comment Share on other sites More sharing options...
