Fusible link melted!

Well i used my ohm meter to find the short and under my steering colum there was is a connector that goes to the ignition switch. When the connector was plugged it I got .2 ohms (almost a dead short) but I found that when I unplugged that connector I didn't read a short anywhere. So I replaced it and it ran for awhile until the small 20 amp fuse blew. I guess I'll run get a 30 or 40 amp fuse tomorrow. Oh and when I was troubleshooting I did bypass the ammeter.
