Hello there, newly registered but I admit to having been lurking for a while. My first post so please be gentle! Whilst lurking I have learnt a great deal, been amused, puzzled, surprised, and confused and learnt that sometimes it is better not to post electrical questions. I have fitted a Smartguage though! My question should be pretty straightforward though I think for some.
We have a 45ft Liverpool sailaway, on the Glos - Sharpness, nearly finished after 7 years but would rather use it than spend too much time on the mooring so progress is slow.
What used to be the standard arrangement on Liverpool sailaways Beta engines with twin alternators was that the B+ on the domestic bank alternator was connected to an insulated post on the engine bed. When you have progressed far enough to connect the domestic battery bank you simply connect to that post.
Mine is done like that, the battery bank is on the opposite side of the engine and the cable runs around the edge of the engine space, a distance of about 8 ft. From what I’ve learnt from this forum, (apart from don’t ask electrical questions!) when I replace the batteries (3x110 Elecsols fitted May 05) I intend to connect the +ve & -ve at opposite ends of the bank rather than at the same end as at present. If I then connected the +ve straight to B+ the cable would then only be about 3ft long. Would this be worthwhile? Now the tricky bit, for me anyway.
There is another cable on the insulated post, a small wire, brown, which I have traced through the loom to the control panel & it is connected to terminal 87 on a relay. What does this wire do? Presumably it is a feed when there is output from the alternator. If I disconnect the insulated post from the B+, what do I do with this wire, extend it directly to B+?
Any help would be gratefully received.
Thanks
Steve
