Alternators and charging faults
Daily highway running between Escobares, Roma and Rio Grande City puts hours on a charging system. We bench test before and after, so you replace the part that actually failed.
Starr County, Texas
Escobares is ten to fifteen minutes east of the shop on US-83. Close enough to drop a vehicle off on your way into Rio Grande City.

You are close. That changes which option makes sense.
Drive it in. It is a short run east on 83 and we would rather look at it while it is still moving than after it strands you.
Ask about a service call. From Escobares we are not far, so coming out to you is usually straightforward. Call and we will quote it.
Call the shop and ask for Ana. Departments running their own units are better off with an arrangement than a call each time something quits.
Escobares sits on the commuter stretch between Roma and Rio Grande City, and the city runs its own police and fire departments. Those two facts drive most of what we see from out there.
Daily highway running between Escobares, Roma and Rio Grande City puts hours on a charging system. We bench test before and after, so you replace the part that actually failed.
A vehicle used for five minute errands never fully recharges, and a battery left partly discharged loses capacity permanently. We test the whole system, not just the battery.
Light bars, radios, inverters and liftgates were spliced in after the factory, often by more than one installer. When a fleet vehicle has a fault nobody can find, it is usually in the added wiring.
Leak detection, compressor clutches, blower resistors and the control circuits that leave a healthy system blowing warm.
You are close enough that dropping off in the morning and picking up after work is realistic for a lot of jobs. Call first and we will tell you whether yours is one of them.
Service calls
A dead battery or a starter that will not turn means the vehicle is not going anywhere. We run mobile service calls out to where you are, so you are not paying for a tow just to find out what is wrong.
From Escobares that is 10 to 15 minutes of our time each way, which is what the call-out covers.
You will know the call-out charge before we leave the shop. It depends on how far out you are and what the vehicle needs, so we quote it on the phone rather than pretending there is one price for everybody.
Asking costs nothing and commits you to nothing. Tell us what the vehicle is doing, and if a tow or driving it in would work out cheaper for your situation, we will say so.
Call (956) 487-2143The same work we do for every town on US-83.
Rio Auto Electric is ten to fifteen minutes east on US-83 at 400 W Main St in Rio Grande City, depending which end of Escobares you start from. We have been there since 1997 and specialize in automotive electrical.
Not necessarily. Call us first. For a lot of no-start problems we can come out on a service call, and from Escobares that is a short run for us. We will tell you on the phone whether that beats a tow for your situation.
We service municipal and emergency vehicles across Starr County, including 12-volt and 24-volt systems, emergency lighting and upfit wiring. Call the shop and ask for Ana about an arrangement for your department.
Almost always a parasitic draw or a charging system that is not fully replacing what you use, rather than the battery itself. Short daily trips make it worse. Testing the draw and the charging output takes about an hour and tells you which it is.

That is usually when people call us. Tell us what the vehicle is doing and we will tell you straight whether we can help.
