My first question is do you have any reason that the fuse blew in the first place ? second it sounds like a simple 5 buck test light is all you need connect the ground clip to a good ground (bolt or screwhead) locate the fuse box I think on yours it's down by your left knee on the top of each and every fuse (except the turnblinker) there are two small metal contacts turn (ing) switch to accy or run should make every fuse hot take tip of test light and touch both sides of each and every fuse in there you should have a light on both sides of each fuse if not replace those that don't test em again still the same (blew new fuse) obtain a light bulb socket from a junk yard or other means (the type for cars) crimp two small spade connectors onto wire ends place known good bulb into socket connect spade connectors into exact spot where fuse goes that blew now the light will light indicating you have a short trace wire when you find short and repair it (you may have to unplug a few connectors) the light will go out or change brightness shorts gone replace with good fuse My first question is do you have any reason that the fuse blew in the first place ? second it sounds like a simple 5 buck test light is all you need connect the ground clip to a good ground (bolt or screwhead) locate the fuse box I think on yours it's down by your left knee on the top of each and every fuse (except the turnblinker) there are two small metal contacts turn (ing) switch to accy or run should make every fuse hot take tip of test light and touch both sides of each and every fuse in there you should have a light on both sides of each fuse if not replace those that don't test em again still the same (blew new fuse) obtain a light bulb socket from a junk yard or other means (the type for cars) crimp two small spade connectors onto wire ends place known good bulb into socket connect spade connectors into exact spot where fuse goes that blew now the light will light indicating you have a short trace wire when you find short and repair it (you may have to unplug a few connectors) the light will go out or change brightness shorts gone replace with good fuse
