Got a compound saw that stopped working, and don't want to just bin it
Anyone help out?
Anyone help out?
make model and suspected fault would be handy
does it hum/arc/spark/or turn
Could be a failed capacitor
if it hasnt got a blade brake[spins freely]try spinning the blade then when your hands clear turn on the power
this will help rule out a dead segment on the commutator or dead windings
was it stored in a cold damp place ??
this can cause the brushes to glaze over and loose contact [lots off sparking]
Capacitors will be connected across the main switch - they can be for motor starting or more likely television interference.
If its connected across the switch then try disconnecting it.
The problem - if all checks out so far - is likely to be in either the stator or rotor windings, and either one is unlikely to be an economic repair, unfortunately.

There could be some burning in there, so check the cables and remove the capacitor for a try. Other than that, they are wired in parallel so there should still be juice going to the motor.
