Battery, Alternator & Starter Repair in San Jacinto
No-start, slow crank or a battery that dies overnight — we test the whole charging system, not just the battery.
Diesel trucks run dual batteries, and one weak battery drags the other down. We load test each battery separately, check charging output under load and measure voltage drop across the cables and grounds.
If the battery keeps going flat parked, that is a parasitic draw. We isolate it circuit by circuit rather than selling you another battery.
What's included
- Battery load testing — single and dual-battery diesels
- Alternator output and ripple testing
- Starter draw and no-crank diagnosis
- Parasitic draw isolation
- Cable, ground and terminal repair
- Glow plug and glow plug relay service
Questions we get
My truck has two batteries. Do both need replacing?
Usually yes. Mismatched batteries in a pair kill each other — we load test both and tell you what we measured.
