Different ways to slice a pie...but for my applications and peace of mind, running a wire back to battery negative terminal neutralizes (pun intended :p ) all the potential confusion, consternation & discord about all things grounding...
^ Yes, manifold/engine/body etc. NOT the frame/chassis. Manifold is 'part' of the engine - it's bolted to it as is the exhaust system.
Essentially the entire engine/transmission/transfer box/body are suspended on rubber from the frame/chassis...
Have a bunch of different Andersen connectors from small to large current and never experienced arcing on the contacts; just wondered what the OP might be doing to cause the burn.
I found a nice vid that shows very clearly the insides movements when being connected, with some suggestions on how to avoid issues (not looked at those, really, so no endorsement of that):
but as to the OP, for context, the forces to connect...
yup, that's right, I remember now, you can mate the black with any other color, at least on some of the sizes of SB if not all.
Having said that, this color keying has never been useful to me so far, so I don't really care. But I can see that...
It is my understanding that within Anderson brand connectors that each of the different colors are keyed differently. Any two of like color will mate, but any mix of colors will not mate. From their FAQ:
I have some vague recollection that, yes, the colors mean different keying, but that are also 2 colors (don't remember which - gray and black?) among the many that are compatible. Or maybe it was that there is one color that fits all the other...
um, no, do not file the contacts. They are plated for corrosion resistance, which is very, very important in an electrical connector. Even a little corrosion is a disaster in the making.
Assuming that this assembly are real Anderson parts they...
It depends on the application: 10% voltage drop for PV panels to MPPT controller might be a deal breaker if, for instance, a 5v threshold isn't maintained to allow the MPPT controller to flow current (minimum 5v differential between resting...
thanks for the vid! yeh so much varying info out there. 10% voltage drop ok. No more than 3%. etc etc.
As for the wire, I got some 105C rated pure copper 370strand 4awg wire so following what the video says, i should be in the clear.
You don't necessarily need to adhere to 1-3% loss for wire length for DC-DC charger circuit; 10%, for instance, allows you to probably go with 4AWG (I didn't do the calc...but 4AWG would be in the general ballpark for feed from alternator to...
FWIW, installed a new Sterling BB1260 in the nose box of our little Escape 15A 4-years ago and it has worked perfectly. Looks like they offer 12v→24v, 24v→12v too...
Why Sterling? For all other LFP battery & solar I am all Victron but didn't...
