Alternator Replacement in Boerne
A failing alternator far out on Boerne Stage Road or at a Cordillera Ranch property can leave you with a truck that will not restart and a long tow to San Antonio. We test and replace alternators where the vehicle is.
Heavy Electrical Loads
Ranch trucks often run winches, light bars, trailer brakes and extra accessories that ask more of the charging system. A dimming battery light, flickering headlights at idle, or a battery that keeps going flat are common signs. We test alternator output at idle and under load, check the belt and tensioner, and test the battery so we do not replace the wrong part.
Testing Before Replacing
A battery that keeps dying is not always the alternator. A worn battery, a corroded ground strap, a loose belt, or an accessory that draws power with the key off can all look like a charging problem. We measure charging voltage at idle and with the lights, blower and accessories on, check the voltage drop across the main cables, and load-test the battery. The alternator gets replaced only when it is the cause.
Light Bars, Winches, and Inverters
Aftermarket lights, winches, inverters and trailer brake controllers are common on Hill Country trucks, and some were wired straight to the battery with no fuse or relay. Those installs can chafe through, drain the battery overnight, or overload a factory alternator. If your truck has extra electrical gear, we look at how it was wired while we are in there and tell you if anything is a fire or drain risk.
One Visit, Most of the Time
We confirm the correct alternator for your engine before driving out, so most replacements are finished in one visit at your home or property. After installation we verify charging output again and check the belt and tensioner, since a worn tensioner can take out a new alternator early.
Cost
Starting at $349 (alternator + installation). Written estimate first.
