Product Details

The SG Tool Aid 28200 is a professional-grade circuit tester built for automotive and fleet technicians working across 12, 24, and 42 volt electrical systems, including modern hybrid vehicles. With an ultra-low 3 milliamp draw at 12 volts, this tester is fully computer-safe, making it ideal for diagnosing sensitive electronic control modules and circuits without risk of damage.

Key Features:

  • Dual LED voltage identification: Blue LED illuminates for 12V and 24V systems; red LED indicates 42V hybrid systems for instant, at-a-glance circuit identification
  • Computer-safe design: Draws only 3 milliamps at 12 volts — safe for use on ECUs, BCMs, and other sensitive control modules
  • Auto-retracting test lead: Wire stretches up to 10 feet to reach deep into engine bays and tight spaces, then retracts automatically to prevent tangling
  • Super sharp probe tip: Penetrates wire insulation cleanly for a solid, reliable test point contact
  • Heavy-duty ground clip: Insulated grip provides a secure, safe ground connection throughout testing
  • Wide voltage compatibility: Covers standard 12V automotive, 24V commercial/truck, and 42V mild hybrid electrical architectures

Whether you're diagnosing a late-model passenger car, a commercial truck, or a hybrid powertrain, the SG Tool Aid 28200 circuit tester delivers fast, reliable voltage detection with color-coded LED feedback. A must-have addition to any professional diagnostic toolkit.

Autoplicity was the cheapest place I could find for my Turbosmart Eboost2. I ordered my controller yesterday and they promptly gave me a receipt and a normal time frame for delivery. Today I got the tracking number and at lunch I got an email saying order complete and delivered. This was an awesome experience and I will definitely be using them next time i'm in the market for a similar product.

Easy and fast

SMOOTH

Awesome price on a name brand part. Good communication too. Many payment plans and you can use your PayPal !!

I placed my order for an Autometer Shift Light and it was shipped the same day. I was provided a FedEx tracking number in the shipping confirmation email. <br><br>Very easy to select what I wanted to buy and the check out process was simple and quick.

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.
