The first order of troubleshooting electrical problems is to check the presence of voltage at the load point in the circuit. Using a test light is a quick way to check for voltage, but a voltmeter is more accurate. Every electrical device also requires a certain amount of voltage to operate. A light bulb will glow with reduced brilliance as the voltage drops. Checking the load point for full battery voltage will tell you whether or not sufficient voltage is getting through. Sometimes undersized wiring can cause low voltage it is not something you will find in much original equipment wiring circuit. A final note regarding repairing electrical faults is that splicing wires do not just twist them together and wrap electrical tape around the connection. Use a solderless crimp-on connector or twist the wires together use shrink wrap electrical insulation tubing to seal the repair.
