Check the oil, apart from lubricating it prevents the engine from overheating, even more so than the whole cooling system, maybe you have no oil, or old oil, and this is why this light turns on.

electrical problems are a headache for sure. Get a good test light and test on both sides of fuse while still in the fuse box. If you have current on both sides the problem is in the wiring to the components. If no power to either side start testing from fuse to main power. If no power to just one side the fuse might look good but is bad = replace. Hopefully just a fuse.

Where is this "transfer case"? Why I ask, os transfer cases are usually in 4 wheel drive vehicles and don't have coolant going through them. I'm suspecting your referring to coolant overflow tank, plastic container... please identify location and a description so we can help you.

  1. The following fuses can cause the car not to start. Check and Replace fuses B, 5 and 6 and 7.
  2. Check the power to the neutral safety switch. When the ignition switch is activated there is no power to the neutral safety switch. Power to the neutral safety switch comes from the ignition switch on the violet wire. If there is no power at the violet wire when the key turns to start, the ignition switch is probably bad or there is a problem with the wiring to the switch.
