I'm having a number of electrical problems with my 740T - blown fuses, directionals keep burning out, horn only works sometimes, fan motor won't shut off completely, and on and on. The only common component I've found so far is the fuse and relay block. I've pulled and inspected them, thanks to the great directions on the board, but I'm ready to try replacing them to see if it makes a difference.

Does anyone know how I can get a compatibility list as I search for a replacement? Since I'm not sure this is the trouble, I'd prefer to get a known-good block from a tear-apart yard or someone with a piece-out car rather than spend the money on a new one. I've heard that the 240's are compatible, but I'd like to find some way to confirm that, or to see what other models may use the same fuse and relay blocks. Thanks.
