Garage sales for $3 maybe? I have a Fluke 88 with a tach function. if you lack one on the dash a cheap tach/dwell meter works. You need the tach to check your max advance RPM and your idle RPM. You have a tach on the dash, no? It works. Don't need anything else-including a manual for it. I've been using a Sunpro/actron CP7504 forever. Rather than dicking with it, ditch it on craigslist (like everybody else) and just get an ordinary, good, timing light. All the computerized stuff gets you nothing but a more difficult tool to use and one with a lot more things to go wrong. I avoid their stuff for a number of reasons-only buy it when I have to.Īside from a possible stiffy from having something labeled "snap-on" (but they didn't make it), i would say the thing is a bad idea. They lack some things when it comes to a being a good company to buy from. Snap on isn't providing a manual for download. The replacement part for what looked like the more likely problem point (the leads) is $155. a whole lot of people looking for manuals and a number of people having problems. Figure since the S marks 6 degrees prior to TDC (or after, I forget) then maybe the advance on the light needs to be set there? Does this sound right? Can this type of timing light be used on an airhead?Ĭlick to expand.I looked around a bit for manuals for that. If I change the advance the S moves up and down. Problem is, without really knowing how this particular timing light works, I am not sure if the readings I get are good or even interpretable. If I set advance to 6, the S lines up in the center of the hole and at ~3000 RPM the Z lines up in the center of the hole. With the light set at 0 advance, the timing marks are unreadable. I have a snap-on computerized timing light (MT 1261A) with tach/advance functions (I don't have the timing light manual, so I basically have no idea what I'm doing - I can at least get it hooked up and the light comes on).Īt idle (~1050 RPM) the light reads about 2100 RPM (twice what it should be). ![]() Right now, I am checking the dynamic timing. I am taking care of a few maintenance items as I gradually get familiar with the machine. 3 Buttons for fine tuning of the speed up to 2 decimal: 0X.00, 00.X0, 00.Hi, I recently picked up a 1989 R100GS. x2 and ÷2 buttons for quick adjustment of flashing speed Slider to adjust strobe light speed between 1-130Hz (60-7800RPM) At this point the rotating object looks like stationary! But, it is moving! So, never touch the moving/rotating object during your test! Then, start fine tuning using the three buttons in the App to get the exact speed. Manually tune the speed using the main slider of the App to see the rotating object looks almost not moving. Turn on the fan in a DARK environment, launch the App on your iPhone (that has flashlight). Suppose you have a fan and need to measure its speed (RPM). You can use this App to use your iPhone as a tachometer that measures the speed of any rotating object. In another word, this App makes your iPhone into a strobe light. Using this App, you can control the flashing on/off speed of your phone flashlight between 1Hz to 130Hz. ![]() It doe NOT work on iPad, iPod touch or any iOS device without flashlight. The App is just for iPhone with flashlight.
