Electrical Diagnostics for Oilfield & Fleet Trucks

- Heavy equipment and off-road machinery
Our goal is to restore reliability and prevent recurring breakdowns that cost you revenue.

Diagnostics identify problems in your truck’s electronic systems by reading fault codes and checking sensor data. This helps pinpoint the root cause of issues like engine misfires, poor fuel economy, or electrical failure.
Can a Faulty Alternator Drain My Battery?
Yes. A bad alternator may not recharge your battery properly, leading to repeated starting issues or system shutdowns. If your battery keeps dying, it’s essential to check the entire charging system.
