Nissan NV Terminal 15 Ignition Positive Interrupted

That sounds frustrating! I had a similar problem with my NV recently. Have you checked the fuse box and the relay switch? A defective relay could cause intermittent power supply to the starter solenoid. It took me forever to figure it out. What about the cable or plug connection?

Thank you for your suggestion. Could you please provide more details regarding the specific relay switch that could be causing this issue? I want to check that before moving forward. Cable and plug connection look ok.

Unfortunately, I don't remember which relay was the culprit, but I strongly suggest taking it to a workshop. The error 'Terminal 15 ignition positive interrupted' does sound familiar, and it might be more than just a faulty relay. In my case, it eventually turned out to be a defective connection. Do you have access to diagnostics tools?

I appreciate your input. I will take your advice and bring it to a professional for diagnosis and repair. Your experience has been very helpful in narrowing down the potential causes and estimate costs. I got it fixed for 95€. Thanks again for your help.
