I would not use solder to make the blades thicker except as an emergency stop gap measure expecting to have to replace the socket later.

I think twisting the blades (slightly) to get better contact is a much better (and certainly more practical) stop gap measure if you have such an immobilization issue again. I'd bet the fuses are part of the issue however - make sure you get good ones. The ones mechanics install for you may not be... so don't assume that.

Chemical cleaning & good fuses are still your best bet - pretty inexpensive path.

Amazon has a value-pack of Littelfuse ATO/ATC fuses for ~$11, would take three of them to get enough of the 5A fuses for a late car, but that's still $0.60 per fuse for a complete set with lots of spares....

Alan, is there a theoretical difference to ATO (open) vs. ATC (closed) in an automotive application?

Particularly to Alan:

I do use Deoxit. Is there a particular brand of fuse that you would recommend? Particularly one that might be available in one of the auto parts chains?

Thanks. I appreciate your input. Maybe if you switch to jet/rocket engine ambulation, I can help you some day.

As noted I prefer Littelfuse which is a well known USA brand - not easily available retail but you can buy at waytekwire.com for example - Bussman is a good brand for ATO(F)/ATC fuses also (but not for the earlier torpedo types though). Bussman is the most widely available brand in retail packaging in car shops - however for the number you need buying online may actually be more economical.

At Waytek Littelfuse ATOF fuses are approx $0.075 each - pretty reasonable to get exactly what you need (get some spares) - and without getting oddballs you didn't need...

Rob - The difference is whether the fuse element is open underneath - in practice this doesn't matter much. Theoretically the element could get corroded by being open - but in our configuration that is extremely unlikely. Either is quite fine to use.

Not really sure how to reply to a post that quoted my post...

Regarding gold plating:
I think you are mistaken. The plug and plate kit uses a brush to apply the plating. You attach an alligator clip to somewhere else on the part and then there is a power supply that goes between the brush and the clip. No disassembly required. I have used this system before and it is a bit tedious to use, but it works. I'd guess that in a couple of evenings you could clean and plate all the contacts and fuses.

Regarding soldering on the back:
I have actually tried this and it proved impossible for me. The spade terminals behind the panels are intended to never be removed and have locking tabs that make it very difficult to remove them without doing a lot of damage. There may be a special tool for this that I don't have, but you will certainly cause more problems than you fix just trying to pull them apart.

Maybe you are thinking of the fuse holders in your 79... go take a look at the GTS panel & tell me how you are going to get a brush in there...? In any case without good cleaning - you are plating on top of oxide...

For the reason you give - I do not recommend disassembly of the panel for any routine maintenance (and have said this many times) - however if you have a major downtime problem - there are tools and techniques to remove the spade connectors - they are indeed pretty secure & most likely you could clean in situ in most instances anyway.

Key is to pull only on the terminals (both sides) - not against the panel. True parallel action pliers make this much easier
If the terminals are so corroded they don't make contact - I think you'd agree they are certainly not good candidates to try to solder together...

I still do think its a very bad idea - there are better ways - that keep the panel modularity intact.

BTW You can also remove any relay & fuse connectors and replace any of these with available & correct terminals (but admittedly these are not easy or cheap to source in small quantities). I have disassembled many panels, and while it is difficult - it's certainly possible.
