We work on semi-trucks, heavy-duty commercial trucks, and trailers from all major makes.<\/p>\n<p><strong><a title=\"Call (877) 425-5143 to schedule electrical repair at one of our 8 TPS branch locations.\" href=\"tel:8774255143\">Call (877) 425-5143 to schedule electrical repair at one of our 8 TPS branch locations.<\/a><\/strong><\/p>\n<h2>Signs Your Truck Has an Electrical Problem<\/h2>\n<p>Truck electrical issues rarely announce themselves cleanly. If you\u2019re seeing any of these, bring it in before it leaves you stranded:<\/p>\n<ul>\n<li>Engine won\u2019t start or cranks slowly, especially in cold weather<\/li>\n<li>Battery warning light or charging system fault on the dash<\/li>\n<li>Headlights, marker lights, or brake lights flickering or out<\/li>\n<li>Electrical fault codes or CEL that won\u2019t clear after reset<\/li>\n<li>Alternator whine or burning smell from under the hood<\/li>\n<li>Trailer lights not communicating with the cab<\/li>\n<li>Accessories cutting out intermittently while driving<\/li>\n<li>ABS or traction control warning lights tied to wheel speed sensors<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Truck &amp; Trailer Electrical Repair Services<\/h2>\n<p>We handle the full range of heavy-duty truck and trailer electrical work at all 8 Betts locations \u2014 from a bad ground causing phantom faults to a complete charging system overhaul.<\/p>\n<h3>Alternator Repair &amp; Replacement<\/h3>\n<p>Alternator failure is one of the most common reasons a commercial truck won\u2019t stay running. If your batteries keep dying overnight, you\u2019re seeing a charging fault, or your lights dim at idle \u2014 the alternator is the first thing we check. We test on-truck, then replace with OEM-quality units from Delco Remy, Bosch, and Denso. Most alternator replacements are completed same day.<\/p>\n<h3>Starter Motor Repair &amp; Replacement<\/h3>\n<p>A click with no crank, slow cranking on a cold morning, or a starter that intermittently engages are all starter problems. We diagnose and replace starters on Freightliner, Kenworth, Peterbilt, International, Mack, Volvo, and Western Star trucks. Don\u2019t guess \u2014 we test the full starting circuit before replacing parts.<\/p>\n<h3>Battery Testing &amp; Replacement<\/h3>\n<p>A weak battery causes a cascade of electrical gremlins that are hard to trace on their own. We load-test your batteries, check your charging system output, and measure parasitic draw to find the actual problem \u2014 not just swap a battery and send you back out. We stock commercial-grade batteries from Deka and other premium suppliers built for heavy-duty duty cycles.<\/p>\n<h3>Truck &amp; Trailer Lighting Repair<\/h3>\n<p>DOT lighting violations get trucks sidelined. We repair and replace headlights, taillights, brake lights, marker lights, turn signals, and interior cab lighting \u2014 on both the truck and the trailer. We carry Signal-Stat and other industry-standard lighting components in stock at most locations. If you\u2019re running a BIT inspection, get your lighting sorted first.<\/p>\n<h3>Wiring Diagnostics &amp; Harness Repair<\/h3>\n<p>Shorts, open circuits, corroded connectors, and chafed trailer harnesses are some of the most frustrating electrical problems to trace. Our technicians use oscilloscopes and advanced diagnostic tools to pinpoint the fault \u2014 not cut and splice until something works. We handle full cab wiring repairs, trailer harness replacement, and 7-way connector issues.<\/p>\n<h3>ECM &amp; Sensor Diagnostics<\/h3>\n<p>Modern semi-trucks run dozens of control modules. If you have fault codes you can\u2019t clear, systems throwing false positives, or communication errors between modules \u2014 we can read, interpret, and diagnose ECM and sensor issues across all major platforms. We\u2019re not just clearing codes and hoping for the best.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t<div class=\"wpb_text_column wpb_content_element \" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h2 style=\"text-align: center;\">Semi Truck Electric Fault Finder Animated Diagram<\/h2>\n\n\t\t<\/div>\n\t<\/div>\n\n\t<div class=\"wpb_text_column wpb_content_element  vc_custom_1782734217335\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h2>Parts Built for Heavy-Duty Use<\/h2>\n<p>The cheapest electrical part is the one that fails again in 90 days.
