If terminal end on wire is still intact remove corrosion, remove relay from holder and push wire and terminal back into holder and hold it in place as you reinstall relay and see if wire terminal grips relay terminal blade.
Rare for me to try and suggest a better approach than Steve's, but here goes. Rather than using coloured crimp terminals, consider obtaining plain brass Utilux or Amphenol (etc.) spade terminals. If not practical to purchase a small quantity (they come in packs of 50 or 100), perhaps purchase a two-, three-, four-, or six-way standard connector pair, which come with identical-sized terminals. In the pic you can see a three-way connector pair that I intend to re-do my brake light switch with, after someone used those horrid (sorry Steve but I really dislike them and they're not up to your usual aircraft-engineering standardsYou can grimp on a new female terminal after you clean up end of wire and crimp it onto wire. Usually depending on wire size you can use one with red/pink color if larger wire use blue color size. Use smallest one you can so it will fit into socket in relay holder.
It won't have a lock tab on it but you usually can force it into socket and hold it there while you reinstall relay.
Alex I agree with you and granted having access to correct terminals like my son did with his last job building things for industry is a plus..

Phew! I certainly didn't want to contradict you or cause offence, I hoped you would understand (with your wisdom) and of course you did.Alex I agree with you and granted having access to correct terminals like my son did with his last job building things for industry is a plus.
I will see if I can find source of supply for correct terminals so I too can NOT use quick fix auto parts store stuff. Thankfully, I have seen an improvement in stock on auto store shelves lately so just maybe I go go upscale, too.
I do miss the tech and engineering support of the aero industry day job I held in days of yore (7 years ago already).
Yes indeed - those are available as well, but as Craig said, most relays have just the standard size terminals.I just measured them and they are 1/4". My bad.
it was the fan relays that screwed me up. those have extra wide, high current blades.
