Electrical Repair

When you're in the Chicago area, our on site truck repair techs will do a full diagnostic on your truck’s electrical system to locate and identify the problem. Accurately diagnosing a truck's electrical problems takes experience and knowledge.

Understanding the relationship between battery sizes and alternator charge rates can help you to locate an electrical problem and possibly avoid future problems. In cold temperatures, batteries don't hold a charge as well, which can often lead to dead batteries or hard starting.

Battery and alternator cables also play a very important role in the proper operating of your electrical system. Though you might have the right battery and alternator, if the cables aren't able to deliver the voltage or charge, you'll have problems.

And if your truck uses an Auxilliary Power Unit, your alternator has to be large enough to handle the extra charging needs. Without the understanding of all aspects of a semi truck's electrical system, diagnosing won't be as simple and straight forward as you'd expect.
