As the title says, Im having problems with my starter. Basically, it wont turn the engine over. It was working perfect, but i took my car out for a test drive the other day, during which the saftey fuse blew. After replacing the fuse, the starter wouldnt would turn the engine. I had this problem before but it was because my battery was on its last legs. I have a brand new 6v battery which reads fully charged everytime I check it. Also, the starter works fine when i hook it up to my modern car via jumper cables. Oh, and all the lights and stuff also work so it doesnt seem to be the battery. Is it a bad connection or a bad starter or something? anyone have any ideas? Thank you.
 
I'm with the others regarding a poor ground.. Clean all the related connections, starter, both battery terminals[remove and clean],, remove and clean the ground cable connection at the frame..
 
I hope your not jumping a 6 volt battery [thats still conected] with a 12volt battery . I had a friend who tryed that once and the battery blew up in his face. Lucky I was there to take him to hospital !!!!!

A starter normally doesn't care about voltage. 6 or 12 is OK, but what jj johnny said about the battery is right on. One of the things that tend to bite you in the hiney regarding an "all of a sudden" starter issue is usually poor ground as stated above. How to test is really pretty simple. Connect 1 jumper cable to the starter bolt, or something on the starter motor that you feel is a good ground. Have someone engage the starter, on the 6V battery only, and as it's struggling connect the other end to the frame or a suitable ground area. If it starts working as it should or speeds up, voila, bad ground. The rest has been covered many times so I won't be redundant, but if you end up rebuilding, shimming the field coils a bit closer to the armature will net you high torque faster spinning starter. Old trick learned from a seasoned rebuilder.
 
I've jumped a 6 volt with a 12 volt battery before, but there is only one way to do it in a half way safe mannner. Have the negative from the 12 volt battery connected to the Model A starter switch. Have the positive jumper cable connected to the 12 volt battery and hold the other end NOT connected to anything yet. Have someone turn the key on and start cranking the Model A on it's battery only. As soon as the starter is engaged touch the 12 volt jumper to a good ground on the Model A. Remove the 12 volt jumper from ground as soon as the Model A starts or if it won't start remove it anyway within 10 seconds and crank no more than 10 seconds.

No point in burning up a good starter if something else is keeping the engine from starting.
