I'm not really good at this so I will try my best to describe as much as possible. My Mahindra 3525 is needing some fix and I need to know where the black wire and blue wire should connect for the timer plug. It feels like the blue is at the right spot already but the black one is pulled out so I'm not sure where it goes now. With the four empty sockets, I filled in the left pin and it made my heater control click, but there's no light indicator it's working. Have any of you faced this issue? How to solve this and how can I fix it?
 
Good that you identified the blue wire's position as likely correct. To confirm, refer to the wiring diagram for your Mahindra 3525. This diagram should outline where each wire connects to the timer plug. You can find one online or through a Mahindra dealer if you do not have a manual. And then address the black wire. Based on your description, the fact that the heater control clicked when connected to the left pin suggests the circuit is partially complete. Yet the lack of a light indicator implies that the connection might not be entirely accurate. Testing each empty socket one by one using a multimeter to verify voltage and continuity. This will help you determine which pin provides the proper connection for the black wire. Ensure the ignition is in the correct position for this test. With careful testing and referencing the diagram, you should be able to reconnect the wiring properly. Let me know if you need more help.

Thank you very much for this. Your input is really helpful to the point I got to fix it myself. I'm going to a dealer later just for a second look but at least it won't cost much for the "checking" as much as I would have spent if I brought it to them for repair. Hoping I can help you out too.

Wow that's some glow up right there. Case closed for this one then :)
