Advanced motor wiring problem

[Sultan]

Hello I have a Curtis DC controller 1205 with an advanced DC motor motor peak 15 horsepower which I have been trying for the last 2 weeks 2Wire appropriately and there's obviously something wrong I was doing because the motor does not spin

Originally I thought perhaps I had a bad motor but when I connected the a1 and the S2 directly to the battery and started to spend

so now I am thinking either I have a bad DC controller which I doubt because it was brand new or something is wrong with my wiring

I did notice did the voltage between a1 and S2 is 51 volts the motor is rated as a 24/36 volt and the DC controller is a 48 volt not sure if those inconsistencies would be a problem

But when I jump A2 to s1 the voltage across a 1in S2 close to zero....

I have attached some pictures anyone who has experiencing this please reach out to me cuz I'm stuck

IIRC
for a series wound motor to rotate clockwise connect
A1 to controller
A2 to S2
S1 to controller

…& for CCW rotation connect
A1 to controller
A2 to S1
S2 to controller

A 48V system should operate in the voltage range of ~52V (fully charged)
…& ~41V (low cut-off threshold)

I have a1 connected to positive terminal a battery on DC controler

I have s2 connected to the M terminal on DC controller

And I have A2 to s1 connected to A2 on DC controler
But I still get no movement?

This does not seem correct.

Try, connecting A1 to your controller
...connect A2 to S1 (only)
…& then, S2 to your controller

* Also, it would be helpful to include pics of your controller (connections)
...& the wiring diagram (for the controller) too

I have the Curtis DC controller 1205

A1 to b+
A2 to A2 to s1
S2 to m-
