What if I changed the starter out with a used unit that tested good, but now the ignition fuse blows all the time? It will allow it to start sometimes & it starts well, but otherwise I have blown about 20 fuses in 2 days. Any ideas?

 

your fuse blowing should have nothing to do with the starter. the started is on a relay and you turning the key on powers the relay. i think you might have to be looking into the wiring.
