GTC General Technologies Corp TA100 Smartach+ Wireless Ignition Analyzer and Tachometer

This is more expensive than some of the competition. The batteries are replaceable so this should last a while.I use this for tuning Carbs.

Case provides good protection, and unit works well. Also useful to establish baselines re: ignition voltages for units working properly, for future troubleshooting reference. A must for synchronous generator set up to ensure proper hertz output. Feels nostalgic, because it feels solid and high quality.

I'm a small engine builder and repairer, lawn mowers, chainsaws, blowers, strimmers etc.I'm so glad technology has moved on and created such an amazing diagnostic tool.It is simplicity in itself. No wires to connect up, no messing with having to earth electrical parts.The most common problems with small engines is they rev so high, particularly 2 stroke enginesused in chainsaws, strimmers, blowers etc.Poor starting, poor running, engines that die on idle can be a problem to diagnose.Engines that are 2 plus years old do suffer from ignition module (coil) deterioration. They are okat high rpm but die out lower down the rev range. Most people make the mistake of resting thespark plug on the engine's metal block, turning the engine over, seeing a spark and assuming thecoil is fine. NOT SO. Once fitted in to the engine and under compression any weak spark will beextinguished by cylinder pressure.By simply resting the antenna on the HT lead with the "HT Voltage" option selected, you canclearly see how much voltage is being generated by the engines ignition coil.If its weak or none at all it will be clearly displayed on the digital screen. You can also if the engineis running but poorly, see the input/output voltage fluctuate. It will also indicate low voltage at idlecausing the engine to die. After fitting a new coil, you can get a min - max output from its memory.RPM Setting : Generators in particular have a max engine speed set by the manufacturer for goodreason. Although most have electronic switchgear to prevent excess voltage output, these systemsare NOT always reliable. The amount of times owners have raised the engine speed in the belief itwill generate more voltage then have the problem of burned out wiring or the overload trips keeptripping out is very common. You can set the engine speed as set on the ID plate on the engine.Mowers, strimmers, chainsaws, blowers have MAX RPM also for good reason. Engines that rev waybeyond those specified by the manufacturer can explode, more often they wear out prematurely.It's a must for 2 stroke engines, most have very specific minimum (idle) and maximum (full throttle)engine speeds. The maximum in some cases can be as high as 10,000 rpm on 2 strokes, 3,250 on most4 stroke engines. No messing about with 12v supply, winding an impulse wire round the HT lead likemy old diagnostic tool. Simply select "RPM" mode, the number of cylinders, 2 or 4 stroke and point theantenna at the HT lead. It will give you and IDLE RPM and MAX RPM, it will save both to its memory anddisplay until you press the "CLEAR" button.A SUPERB BIT OF KIT WELL MADE WITH ROBUST RUBBERISED CASE, RELIABLE AND ACCURATE, WORTHEVERY PENNY

This is the best tool for small engines and ignition issues in cars and trucks. Its easy to use and accurate.

Came in record time and works great!!
