I have a 2005 cummins and when I cycle the key on it blows the 2 amp ignition feed switch fuse. Has anyone had this problem if so can you help me out it is giving me a headache.

Thanks

 

Yeah I had that happen and put a 5 amp in no problems in over a year. When you cycle you mean turn it over if so the starter is starting to draw alot more due to being worn out or maybe damaged/??
