electrical problem

I have been trying to get my bike going and have upgraded the ingnition to dyna s and wired the coils according to wgcarbs tech the fuse to the relay ugrade is also blowing when the bike cranks and runs but the headlight will not come on and now the taillight has stopped coming on also it has the original wiring harness any help is appreciated

It may be your fuse box, take a look at it. Are the three fuse clips tarnished, corroded? You can replace that fuse box with a new style that uses the new blade style fuses. This may be all it needs.

You can use these:


or this:


Also make sure the connections in the white square are very clean. Corrosion in this plug coming from the regulator/rectifier will add lots of heat and put bad juju into your system. Don't ask how I know this.....

thanks for the help I try a few things and let you know how it turns out

headlight had some corrosion and cleaned up also had a wire not hooked up properly for wgcarbs coil upgrade and had a bad bulb in tail light thanks for your help:)
