What size wire did you use? Too small will allow it to over heat and loose connection.
The fuse may be of several types, some should be pulled with the plastic tool that comes with them. Glass; I use a small plastic prybar. Large prong type I use needle nose pliers. And the small blade type I use the tool that comes with most kits.
May I recommend check ground first - keeping in mind that an eyelet near the headlight to a frame piece does not signify ground. I put an Ohm meter between my chassie grounds and the battery - just to make sure.
Delivery of power is next - if you have a meter, read the voltage. Better, read it and wait. If the power drops off slowly, you may have a wire overload and it heating up. If it is quick like a snap, might be a fuse. DO yo have the right size fuse installed?
Well I hope this helps.
