Fw: (ET) Master Switch & Fusible Link



I blew the fusible link on my E10M some years ago. I got a new one from Bill that time. I just did a quck Google search on fusible link. It turned up several web pages, but I think this link is the one to try first:

This shows Fusible Link Wire kits which look like they might work well, Some background and suggestions are also given. The prices shown are only in the $3-$5 range. It looks like one of these would probably work with a sheet of bakelite as Mike suggested.
 
I also found fusinle link wire at Checker Auto Supply which worked temporarily, at least. A Golf Cart place also might have some with higher current ratings.

You can get this same disconnect switch from JC Whitney for about $24 vs $27 from EV Parts.  Shipping costs look about the same.
 
As for the fuseable link, none of the "off brand" manual disconnects will have anything like it already attached.  I believe that the ones Bill Gunn supplied had been modified, by him, to be able to still use the original fuseable link.  Shouldn't be a big deal to add a piece of sheet Bakelite with a couple holes drilled in it to mount the link and use the switch's own terminals to hold it all in place. 
 
It's not the easiest thing to do, but the OEM disconnect switch can be taken apart and the contact surfaces cleaned to sorta "rebuild" it.  Seems like I may have even put in a stronger spring in one some years back, but it's still a marginal unit.
 
Anybody got a theory, or first hand experience, as to whether or not we even need the fuseable link?  Has anybody ever "blown" theirs?  Or are they just another place to burn your fingers when looking for bad/high resistance connections?
