It offers real-time waveform visualization, spark peak voltage measurement, and timing diagnostics, enhanced by advanced charting to detect intermittent faults, making it indispensable for marine, motorcycle, and automotive applications. ## Description The GTC505 Engine Ignition Analyzer is a handheld instrument designed from the ground up for the diagnosis and performance measurement of all types of spark ignition systems, from conventional to the newest Coil on Plug in use. The GTC505 is capable of displaying and measuring the following in real time: secondary ignition waveform, primary coil current ramp time, dwell time, spark burn time and RPM. It also provides two innovative and unique display formats used to compare measurements between cylinders, and to look at data for hundreds of spark events over time in order to detect intermittent problems, misfires and other performance issues which are very difficult to detect using conventional scopes. Review: Muy buen articulo Review: Great tool! Works very well great for quick detection of misfires easy to use! ## Features - Measures spark peak voltage, for finding primary and secondary coil faults - Displays ignition waveforms in real time, allowing for detailed analysis - Detects ramp time (or dwell angle), for diagnosis of timing issues and primary coil faults - Has chart and comparison functions, allowing the user to find intermittent issues - Works on all spark-ignition engines, from small 2-stroke engines with magnetos to modern cars with computer-controlled coil on plug systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001TD5JYE | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #65,939 in Automotive ( See Top 100 in Automotive ) #1,528 in Automotive Diagnostic, Test & Measuring Tools | | Brand | GTC | | Brand Name | GTC | | Customer Reviews | 4.4 out of 5 stars 318 Reviews | | Global Trade Identification Number | 00833303000688 | | Included Components | GTC505, flexible probe, coil on plug pickup, spark plug wire pickup, USB micro cable, AC adapter, user manual | | Item Type Name | GTC505 Engine Ignition Analyzer | | Item Weight | 907 g | | Manufacturer | GTC | | Power Source | Battery Powered | | Power source | Battery Powered | | UPC | 833303000688 | ## Product Details - **Brand:** GTC - **Power source:** Battery Powered - **Automotive Fit Type:** Universal Fit - **UPC:** 833303000688 - **Global Trade Identification Number:** 00833303000688 ## Images ![GTC505 Engine Ignition Analyzer - Spark Diagnostics and Tachometer Readings for Marine, Motorcycle, and Automotive Mechanics, General Technologies Corp - Image 1](https://m.media-amazon.com/images/I/612AX+MwL5L.jpg) ## Questions & Answers **Q: Is this top of line ?** A: It's, as far as I know, a unique product. No-one else makes anything quite like it (as a handheld, one-box solution). I've got one, and it's a fantastic time-saver. I can do a quick look at four cylinder's worth of ignition waveforms in twenty seconds. To do the same thing with my Snap-On Verus (five grand's worth) takes five minutes to boot, then a couple of minutes to find and plug up the adaptor, then another minute to configure the scope mode. And I gain little or nothing more by doing it with the Snap-On tool than using the GTC product. **Q: Will this work on a single cylinder lawnmower engine to read rpm? If so what setting would you use?** A: The problem is that when the unit is in tach mode it reads the wrong RPM’s because you you can not set it for the number of cylinders that your engine has. It’s permanently set for “8” cylinders with no way to change it to “1”, “2”, “4”, or “6” cylinders so that the tach function will read correctly. You have the option of setting the unit for a 2-cycle or a 4-cycle engine so why can you not set the number of cylinders? **Q: Does this product have a warranty besides the 4yr protection plan?** A: Yes, the GTC505 comes with General Technologies Corp's standard product warranty, which lasts 1 year (from date of purchase). Please visit the GTC warranty page for details https://gtc.ca/warranty.html If you have problems after the warranty period, please contact the manufacturer, as GTC can often provide replacement parts, or repairs. **Q: Can this be used to set ignition timing instead of a timing gun?** A: Nope. There is no strobe to illuminate the timing marks on the vibration damper. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Muy buen articulo *by J***Z on 23 May 2025* ### ⭐⭐⭐⭐⭐ Great tool!
