You cannot tell if fuses are good by looking at them. You need to remove them all and test with an ohmmeter.

Have your battery and alt checked checked by auto repair shop or parts store. Many will do this for free.

yeah sounds like your tacho fuse has blown like half your gauges run off this one fuse you can check them in there just get a multi meter put the earth on the body some where and if you get 12 volts on one side and not the other it is blown

note:the accesory you are tesing has to be on

good luck man
