Review: Find that shorted wire! - I saw this tool on a You Tube video and how it is used...bought one for myself. First time I used it, I found a shorted wire bundle where a careless body shop mechanic cut into the bundle when replacing the floor board in my 56' Chevy. With all new wiring...a short was not what I expected. This tool found it without any problem! Liked it so much...bought. one for my brother who was chasing a short the old way...to no success. He got nailed with a 510.00 repair bill before he received his testor! He has since used it and loves it too. Great tool, great price, fast delivery. Review: It helped me find my short, but not the way it's supposed to. - Take your victories where you can :) Been looking for a short in the parking lamps on my 2004 Lincoln Town Car for like 6 weeks, probably spent 50 hours on it and replaced all kinds of parts, disconnected everything I could, etc. Anyway, this little sucker works by pulsing some current through the fuse slot that was blown. Hooked it up and started to look around, since I could disconnect everything except for the wiring to the headlights I started there. Looking at the connector to the headlights I swore I saw a little flicker of light, stared at it for a while and there it was again. Turns out the connectors in the connector were a little messed up and were intermittently touching each other, so it wasn't the gauge with the short finder that found it, but the capacitor sent the current and I visibly saw the hot spot where they were connecting. Problem solved, so it helped, just not how it was originally intended. Success story anyway. ## Features - Used to locate shorts quickly in 12 volt automotive circuits - Operates through metal parts, panels, fiber and plastic materials - Schematic included with instructions - Furnished in a clear box ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000RFLR0U | | Best Sellers Rank | #674,312 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #731 in Circuit Testers | | Brand | Tool Aid | | Brand Name | Tool Aid | | Color | Clear | | Customer Reviews | 4.5 out of 5 stars 491 Reviews | | Global Trade Identification Number | 00600161249135, 00638570251005 | | Included Components | Item | | Item Dimensions | 5.7 x 1.4 x 5.7 inches | | Item Weight | 0.35 Pounds | | Item dimensions L x W x H | 5.7 x 1.4 x 5.7 inches | | Manufacturer | SG Tool Aid | | Minimum Operating Voltage | 12 Volts | | Model | 25100 | | Power Source | 12v Automotive Circuit | | Specification Met | CE, CSA, EMC, EN 61010-1, ETL, FCC, IEC 1010, IEC 61010-1:2000-1, IEC 61326, IP 40, IP 67, ISO 9001, NIST, REACH, RoHS, TIA, UKCA, UL | | Style | Modern | | Style Name | Modern | | UPC | 600161249135 523161027179 055555595563 086000214708 638570251005 | | Unit Count | 1.0 Count | | Warranty Description | Lifetime warranty does not cover abuse | ## Product Details - **Brand:** Tool Aid - **Power Source:** 12v Automotive Circuit - **Style:** Modern - **Color:** Factory - **Item Weight:** 5.6 ounces ## Images ![SG Tool Aid 25100 Short Tester - Image 1](https://m.media-amazon.com/images/I/61SkaZ1rQAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Find that shorted wire! *by A***R on June 19, 2016* I saw this tool on a You Tube video and how it is used...bought one for myself.

Success story anyway. ### ⭐⭐⭐⭐ Works great for constant shorts, but ECT2000 is a more modern and expensive version for more complicated scenarios *by C***Y on December 18, 2015* I prefer the Power Probe ECT2000 Short Open Circuit Detector to this one. Both accomplish the same task. Neither is really user friendly, but just help with your troubleshooting. This short finder works. it tells you the direction of the ground using the needle. The ECT2000 has an arrow light that tells you the same thing along with a beep if there is current flowing. For me, I was frustrated finding an intermittent short. I found out afterwards that the short only happened while turning the steering wheel in my car. In this circumstance I found a light bulb that had no current so I hooked up the ECT2000 to the light bulb socket, and traced how far the current would go backwards. The SG tool aid couldn't help me at all, but the ECT2000 could. Granted, the ECT2000 is much more expensive, so if you have a constant short or a fuse that blows right away after replacing, this is what you need. ## Frequently Bought Together - SG Tool Aid 25100 Short Tester - General Technologies Corp GTC CT6100 Fuse Socket Connector Kit , Yellow - Power Probe ECT3000B Short/Open Circuit Finder in Automotive Diagnostics - Tool Only (no Accessories or Box) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/4651012-sg-tool-aid-25100-short-tester](https://www.desertcart.tn/products/4651012-sg-tool-aid-25100-short-tester) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-24*
