A good diagnostic challenge for the team this week on a 20kVA TechnoGen generator fitted with a DSE (Deep Sea Electronics) controller.

The generator came to us with a no-start fault. After carrying out a systematic diagnosis and testing procedure, we traced the issue back to a failed solder joint on the controller circuit board.

The faulty connection was repaired by re-soldering the joint, restoring communication and allowing the generator to start and run correctly once again.

This job is a great reminder that not every fault requires expensive parts replacement—accurate diagnosis can save customers significant time and money.

If you're having issues with generators, heavy vehicles, or diesel equipment, get in touch with Mainstream Diesel. We specialise in finding and fixing the faults others can't.

We got called out to an excavator with zero dipper function — not ideal when there’s work to be done. After a full diagnosis, we tracked it down to a jammed spool in the valve bank.

Pulled it apart and found metal contamination had caused damage 👎

✔️ Removed and cleaned the system
✔️ Replaced hydraulic oil & filters
✔️ Machined the spool to remove burrs
✔️ Honed the valve bank slice

Got everything cleaned up, reassembled, and running like it should again 🔧

Back to work with minimal downtime — that’s what we’re about.
