Adrian Posted May 24, 2018 Report Share Posted May 24, 2018 Hi all, just one of this stupid moments, no matter how many pictures you take you always miss what you want! I’m looking to put some heat shrink on the battery earth, just to tidy it up and more easily cleaned in the future. The main battery strap has an extra clip close to the terminal which is preventing the heat shrink from going on. I can’t remember if it was originally attached, if it was it would be on the edge of the battery box support. is kit necessary to attach it?

yorkshire_spam Posted May 24, 2018 Report Share Posted May 24, 2018 On my RHD Spitfire 1500 (1977 build) it's fitted like this, but I can't vouch for whether or not it's fitted "right" or not: Link to comment Share on other sites More sharing options...
daverclasper Posted May 24, 2018 Report Share Posted May 24, 2018 Hi. Not sure that you need to clean the earth cable a such (apart from the connections if need be)?, maybe some maintenance spray to protect from the elements . Any larger obsticle will stop the cable feeding into the heat shrink. A crimp tool to reconnect the cable, or a good alternative way?. Hair dryer to shrink the heat shrink.

Pete Lewis Posted May 24, 2018 Report Share Posted May 24, 2018 If its just to tidy up get some pre split copex sleeving Pete Link to comment Share on other sites More sharing options...
thescrapman Posted May 25, 2018 Report Share Posted May 25, 2018 Just spiral wrap it with yellow tape. it should go round back of battery by the way Link to comment Share on other sites More sharing options...
Adrian Posted May 25, 2018 Author Report Share Posted May 25, 2018 Thanks for the replies. Clamped on side like Yorkshire and round the back like the scrap man. Didn’t bother with wrap in the end. Cheers Adrian Link to comment Share on other sites More sharing options...
NonMember Posted May 25, 2018 Report Share Posted May 25, 2018 That is the correct arrangement. Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 25, 2018 Report Share Posted May 25, 2018 Adrian, A battery clamp is a good idea. You probably haven't got around to putting it back? An MOT fail, if you're taking it! Doug Link to comment Share on other sites More sharing options...
thescrapman Posted May 25, 2018 Report Share Posted May 25, 2018 There was a requirement to have the earth lead marked in yellow come in at some point during Triumph production. During the 70's I reckon Link to comment Share on other sites More sharing options...
JohnD Posted May 25, 2018 Report Share Posted May 25, 2018 I think that is/was a Motorsport, not a production requirement. It dates from before the days of the FIA cut-out, and let a Marshal armed with bolt cutters disable a battery quickly (?!) The earth lead still has to be in a "distinctive" colour, not just yellow,despite the cut-out switch being mandatory. John Link to comment Share on other sites More sharing options...
Dick Twitchen Posted May 25, 2018 Report Share Posted May 25, 2018 John Thomason's 'Guide to Originality' has a photo and mentions the yellow sleeving appearing on the Mk3 Spitfire; interestingly after the statement '...now a negative earth vehicle.'.

JohnD Posted May 25, 2018 Report Share Posted May 25, 2018 Motor Sport Association's Yearbook, section J, Competitors' Vehicles, para 5.14.5. "Have the battery earth lead, if not readily distinguishable, identified by a yellow marking." The "Distinctive" ccolour is for tow-rings - my mistake! Dick is of course correct in quoting Thomason. Modern domestic wiring uses yellow/green, or green as the colour code for an earth, but I think that in the UK the yellow is long post-1967 and was green alone before 1977. So that doesn't explain why Triumph used a yellow sleeve. No sign of it in any "Construction & Use Regs", I fear, and it doesn't happen today. As I mentioned, it's redundant nowadays in motorsport, but I don't know when it was introduced. A Q I'd have to ask the MSA, if they have a historian.

Adrian Posted May 26, 2018 Author Report Share Posted May 26, 2018 Battery clamp now on (just timing on the photo). I just love the extra info you get from the community, may not help the problem but builds background knowledge. Now I’ve got to figure out the wiring connections for the lights etc, and try to figure out if the scotch lock red cable with two terminal blocks (domestic) actually did anything! Shaun, it’s taken a while to get to this stage and I started with a good external example, just engine, inside and underside needing nursing. There is part of me feeling inadequate because I’ve never welded! Link to comment Share on other sites More sharing options...
