Nice old Lucas split charge relay to fit - advice required

i picked up this old stock split charge relay last year and have been reluctant to fit it because of a lack of knowledge really , but i do like the originality of old parts and the company i got it from have a good name in old spares supply and have ensured me it is genuine old stock never been fitted etc so i am keen to give it a go .

These are the bit's i have cobbled together plus i have a new earth strap courtesy of Rick .



i caused the brown patch on the bottom corner by leaving it against a damp box .



lucas part 3335 , relay .


The tags have been labeled up and connected by me for reference , they say ignition light feed , earth , main battery and leisure battery .

questions --

Where does the ignition light feed pick up , is it the regulater ?

where does the main battery pick up ?

where best to earth it ?

Will the 27 amp red cable be strong enough to do the + side of things ?

cheers in advance , Malc

 

cheers for that , i was concerned about the cable tbh but Halfords said it would be fine - raises eyes to ceiling !

 

Besides i like it , its all bulky n that !

 

My biggest worry is whether Rick made it while he slept worked at Lucas ! :help-sos: :help-sos:

 

made uk 12 79 ?

too late foor my bus so it will have to be a bone fide extra !

 

Were they not good?

 

i tried a serious thread !



And failed again --rotten lot
