These pictures show the circuit and some melted wires similar to what I had to replace.
Step 1: Components & Materials Needed
A PCB soderness board (I reused one that I had bought for something else 10 years ago)
2 automotve 12V headlamp/taillight relays 10Amp
2 1000 Ohm (1K ohm) resistors
2 LEDs, 1 Red, 1 Yella (2V each)
An assorment of short wires (14 guage) and for the LEDs any small guage will do.
2 10 Amp fuses doesn't have to be automotive but it is easier to work with.
Wire connectors (Male/Female assortment)
A DPDT slide switch to turn off when not in use.
Soldering Iron and RA core solder to stick
A pair of helping hands will help with alligator clips
A drill to widen the PCB board holes to take the more larger components
A lot of patience because these things are small and in a crampt area
The picture of these cool components courtesy of Google Images, and two pics of the underside of the circuit, here you can see where the patience comes in.
