Hi all,
I have bought a Dewalt DCG418 54V angle grinder I want to repair.
The grinder is completely dead and upon taking it apart I think the motor is okay. There is no obvious burning or damage to the armature that I can see. I hooked up an 18V battery to two of the 3 terminals you can see directly on the motor and it tried to turn over. I didn’t get full turning or start up presumably because it’s a 54V tool but I found that encouraging.
I want to try and make a circuit from the 54V battery straight to the motor to check it’s good and indirectly confirming a wiring fault before going any further. However, I am unsure which of these terminals is positive / negative and don’t want to risk damaging the armature nor the very fault-sensitive flex volt battery. I have also bypassed the switch and this isn’t where the fault is so it’s either the wiring from the other side of the switch to the motor, the capacitor in the circuit or the motor itself.
Any tips on how to best proceed?
