One thing I often do to ensure a durable, reliable electrical system is use heavier duty battery cables instead of the stock OEM or aftermarket cables. Sometimes, I have these battery cables custom-made using heavier cable and better connector terminals.
Because I live in interior Alaska, with winter lows frequently below negative forty degrees F, I typically use arctic grade cable from
Polar Wire Products.
Alternatively, I will sometimes buy the heavier battery cables used on the big diesel engines in heavy construction equipment. (This works in Anchorage and points south ... locally, construction companies buy battery cables from Polar Wire.)
In terms of heavier cables, if the OEM battery cable uses 4 AWG cable, I go to 2 AWG or even 1 AWG cable. In turn, heavier OEM cable means even heavier custom cables.
