Modern Vehicles Need More Than Guesswork
Vehicle electrical problems can come from batteries, alternators, starters, wiring, sensors, fuses, modules, poor grounds, or computer-controlled systems. We test the system before recommending parts.
No Start / Intermittent Start
Testing battery condition, starter circuit, ignition relay, wiring, and related electrical causes.
Battery Light / Charging Problems
Alternator output, belt condition, voltage drops, weak battery, and poor connections.
Electrical Shorts & Blown Fuses
Fuse issues, wiring faults, parasitic draw testing, and electrical circuit diagnosis.

Sensor & Computer Issues

Battery Drain
Testing for parasitic draw and electrical issues that leave a vehicle dead overnight.
We Test the System Before Replacing Parts
Electrical problems are not always obvious. A dead battery may be caused by a charging system issue, a bad connection, a parasitic drain, or a component staying on after the vehicle is shut off.
JCR Auto Repair uses diagnostic testing and hands-on inspection to narrow down the source of the issue before recommending repairs.
