Start relay smoking after AAW install.

I've been gone all day, obviously got here "late" just some random thoughts

NEVER leave a wire / battery/ power source connected if something is getting warm or smoking. (Maybe I read something into this)

I've "preached" this many many times. When you are making wiring changes, rewiring, or even trouble shooting shorts and heavy unwanted current draw, stick a LAMP in series with battery ground

Use a lamp intelligently--sized to the trouble at hand. a 12V test lamp is nearly useless in this situation. I normally use an old 1157 bulb and socket as you can wire it up to cause it to draw different current You have a bulb there with a low current filament--the tail lamp filament, and a heavier one--the stop/ turn filament

For lightest current, use the two lamp wires for connection, and leave the ground/ shell INSULATED (unconnected) This puts the two filaments in series

Next up, use the shell as one connection, and the tail wire, leaving the stop/ turn wire unconnected

For heavier current, use the shell and the stop/ turn wire, with the tail wire unconnected

And finally, for heaviest current combination, twist the two socket wires together, and use the shell as one connection, and the common of the two wires, lighting both filaments

For heavier yet, use a headlamp

WHAT THESE DO, is you have a lamp in series with battery ground, and this LIMITS system current. You can throw a wrench across any hot connection to ground, and the only thing that will happen, is that your lamp "protector" will light up, limiting current flow.

But if you use a heavy enough lamp, things will somewhat work allowing you to easily troubleshoot. For example, using a series headlamp protector while troubleshooting lighting problems will allow most the lights to at least glow, giving you visual indication
