A dead battery keeps a box truck off the road, so we test and repair charging systems in our Yorba Linda shop for Corona fleets. We load-test batteries, check alternator output and voltage drop, clean corroded terminals and cables, and find parasitic draws so your Inland Empire truck starts every morning and holds charge on route.


## What this includes
- Battery load and state-of-health testing on single and dual-battery setups
- Alternator output, ripple, and voltage-drop testing under load
- Terminal, cable, and ground cleaning and replacement
- Parasitic-draw testing for batteries that drain overnight
- Battery replacement with the correct group size and cranking rating
- Charging-circuit and fusible-link repair
- Dual-battery and isolator diagnosis for upfit and liftgate loads

## Who it is for
- Corona fleets facing slow cranks, jump-starts, or repeat dead batteries
- Operators running liftgates or refrigeration that drain batteries on Inland Empire routes
- Fleets that want charging health checked before cold mornings and long idles

## Pricing
Battery testing and replacement sit near the low end; charging-system repairs reach the high end. Electrical labor billed at $260/hr, diagnostics at $285/hr.

## FAQ
### Why does my liftgate kill the battery?
Liftgates draw heavily, and a weak charging system or bad isolator cannot keep up. We test the whole circuit so Corona trucks stop stranding drivers mid-route.

### Is it my battery or my alternator?
We load-test the battery and measure alternator output and voltage drop separately, so Inland Empire operators replace only the part that actually failed.

### Do you handle dual-battery trucks?
Yes. We diagnose isolators, verify balanced charging, and match replacement batteries so your Corona box truck's dual system stays reliable.
