One of the best electric trailer brake tester I've ever used is ....... a selaed beam headlight bulb.
Put two short wires on the bulbs spade lugs and first put it between the TV's brake lead and the ground pin. When first connected you should get a flicker then it goes out. Next have a helper manually apply brakes from inside the TV, it should fade to full brightness. If it does the TV & its wiring are fine.
Next put the bulb between the trailers brake connection and the TV's brake line with a jumper between ground pins. Repeat the above test. If the bulb fails to light, or lights but differently than the first test you can start digging further into it.
