Interstar Terminal 15 Ignition Issue

Sounds familiar. I had a similar problem with my Interstar. Check the starter solenoid, and look for any voltage drop in the wiring harness. It could also be a circuit break related to the power supply.

Thanks for the quick reply! Where exactly is the starter solenoid located? And how would I check for a voltage drop? I'm not super experienced with car electrics, so any pointers would be amazing!

Honestly, checking for voltage drops can be tricky without the right tools. And getting to the solenoid can be awkward. I'd just take it to a workshop to be safe. They’ll sort it out quickly.

You were right! Took it to the workshop, and it was a dodgy connection. They sorted it for 95€. Thanks for the advice!
