If the questioned circuit keeps blowing fuses--replace fuse with a test light--light will illuminate as long as there is current flow to ground (Short) when short is found and removed (bad wire etc,) light will go out

Swap out any mains leads for a known good one
Get a cheap multimeter or bulb and battery set up to detect short circuits.
Start from live pin of plug with one terminal of tester and move to the switch or fuse point and check switch and fuse work as normal.Check switch poles are not shorted live to neutral. Check live to Earth or case of equipment. No current should flow.
Check transformer primary is around 100 Ohms and the lamp or meter needle is slow to react by inductance of the coils. Immediate move to full scale deflection indicated shorted turn of transformer.
Unscrew printed circuit board and look for blackened areas caused by a spark.
Disconnect each part in turn to isolate problem.

This grounding of the circuit is what caused the short circuit. Find the short circuit before re-fusing or turning the breaker back on.

Why is the breaker tripping when you turn on the oven?
An electrical short in the wiring, or a defect in the oven itself. Have it checked out by a qualified technician.
What is the process for fixing a short caused by your turning lights?
Hey Ray==I presume the fuse is blown is why you think there is a short. You have to examine the wiring to find where the wire is shorted out. If you have a trailer harness, start there. If the vehicle has been wrecked. look there as body men have a habit of pinching wires in the repair. If not, you just have to follow the wiring harness and find out where it is. Goodluck, Joe

89 suzuki sidekick and the running lights have a short how do you track down the short?
Replace the fuse with a test light Turn on running lights (test light should illuminate) Remove bulbs one at a time Check fixtures until test light goes out - this will indicate area where short is Further investigate wiring in this area
