DC40
« on: February 03, 2019, 04:15:13 PM »
Hello all, 1st post etc

The brush on my DC40 isn't spinning.
Ive had the brush assembly to bits and cleaned it, nothing.
The best i can get coming out of the power connector to the brush assembly is just over 5V?
Its a DC motor on the brush assembly?

Any ideas anyone?

Yes it will most likely be >>this loom<<. They are known for it.

You need to see a DC (not AC) output of about 300-320v. PCB is a possibility but that loom is more likely.

If as mentioned dc high voltage is there then motor at fault, if not... then loom or pcb at fault.
The only failure is not to try.

The loom doesnít look damaged, belled out and 0.2ohm on each core. So it must be the pcb?

always wise to give the loom a waggle when checking on the meter.
If you have no voltage to the motor and you say the loom is ok, then either the motor or pcb at fault.
You could also check for 240v ac~ input to the pcb too to confirm cut out and axis switches are working.

It's hard to diagnose through the keyboard, in the real it's easier to find fault.
