Hi Dan
Go down to supercheap and buy one of these (if you don't already have one)
https://www.supercheapauto.com.au/p.../562987.html?cgid=SCA0106060403#start=11I hate electrics with a passion, but had to put in a new alarm system battery - and one of the terminals had to be cut off due to corrosion. Did it in 5 minutes - not hard at all
First cut the old bits off, 2 strip the wire - probably a 1.0 thickness. Note, turn the whole crimper to slice through the plastic coating right the way around, then pull outward to get it off.
Put on the correct size connector and crimp it closed using the equivalent size at the top (blue connector = crimp location beside blue dot)
If I can do it, anyone can
