Can be tedious but with your simple system not bad. Just be thorough and you'll find the issue.
Potential issues: transformer, cable, LED fixtures, LED bulbs, connections.
I don't heat shrink my connections - I use wire nuts filled with dielectric grease.

heat comes from current and resistance
P = I^2 * R
If there is a short or really a ground, it will heat up the wire. If you have a wire smaller than the rating of the transformer, it could heat up to the point of fire.
