Step 35Verify & Label Wire Ends of Splitter
Use an ohm meter to make sure you know which wire is positive and which is negative. If you don't do this right, you could end up blowing fuses or damaging your bike generator. Set you $10.00 volt meter from radio shack to a resistance measurement.
Next put one hand probe on the end of one wire and the other Ohm meter hand probe on center contact post of the cigarette lighter plug. You will see it when you look down into the barrel of the cigarette lighter plug. If the ohm meter shows 0.2 to 1 ohms then you know the wire you are holding is connected to the positive terminal.
GET a piece of tape and mark that wire so you make no mistake when putting it together. If the ohm meter doesn't show any measurement change when you touch the two ponts, then switch your hand probe to the other wire end to confirm that it is the positive voltage wire.
(2)Do the polarity check described above on both pairs of the ligarette lighter sockets. Now twist their wire ends together. Make sure the positives are twisted together.
(3)Now crimp on the ring terminals to the ends of these wires.
(4) Now to make extra sure you don't get mixed up, mark the conectors positive and negative with a permanent marker as shown below.
