No power.just clicks when you pull the trigger

Sounds like it could be one if sveral fixes to try. Open the handle with the switch with it unpluged for safety. Have a look at the incoming wires for burnt or disconnections. ALL ok then if you have a multi meter or voltage tester plug it in be careful, check for power coming in using the saw as ground. Then check again from the neutral to hot (white to black). All good then go from the White coming in to the out going terminal, I have no picture of the color or which is the outgoing terminal, sorry, as you click the switch. Some units have a switch with a brake in it, this coud be faulty but not usually. If good so far and you have voltage outgoing then unplug again and you will have to follow the circuit wires thru the case to the motor Usually some access is available to follow, take your time removing things and good plan to take pictures as you go so reverse is easy. I have had sawdust under the brushes, I have had no brush left. Smell all around the saw for burnt, and around the armarure as well as look for burnt wiring. Again using the volt meter press the switch and check for voltage at the brushes. If you are not happy checking electrical things hot then do not . You may have found out now the incoming vord is open, the switch is faulty, or some dust or wood chip under a brush.
