one of my 50 amp under hood fuses blew last night . i figured it was just my msd pulling too much current so i put in a 60. it blew again goin down the road after about 2 minutes. anyone had this problem. im gonna take the box off today and see if i can get it to stop blowin fuses.

 

You are drawing too much current through the circuit so either you will need a dedicated circuit or check all of your wiring to make sure it isn't grounding out.

 

the first time i blew the 50 amp, i replaced with a 60 amp to compensate for the extra current. well that time it lasted about 5 minuted and blew going down the road and a tiny puff of smoke came from under my dash. my msd is wired up correctly, if it wasnt it would not even start. i don't really see how that fuse has anything to do with my ignition . could it be a main relay? some guy said that was his problem wen his fuse kept blowing. maybe the relay just decided to kick the bucket?
