Overview

These devices measure the change in inductance in the magneto coil when the points open and close. Simply shorting the clip leads together will not indicate a point closing, therefore eliminating any false reading caused by loss of contact to the magneto grounding terminal. To use, simply remove one plug from each cylinder. Connect black clip lead to engine ground. Connect red and green leads to right and left magneto terminals. Turn propeller slowly. When the points open the L.E.D.s will turn off and the audio "tweeter" will sound. The magneto connected to the red lead will sound a rapid beat and the magneto connected to the green lead will sound a slower beat. When both sets of points are open, a third and continuous sound will be emitted. Adjust magneto timing accordingly.

100% solid state, compact 3/4" x 3" x 5" size, long battery life. Color coordinated leads are 4 ft. long. Comes in strong anodized aluminum case. Also available for single magnetos and without tweeter. The single timer is more expensive now because it is a new, updated version or style. This is a deluxe style with tweeter that has a sound system and 4 foot leads.

Great item, fast ship.

A very useful unit, worked great on my old (1958) BMW motorcycle. An additional paragraph in the instructions on how to use the tool with a magneto ignition motorcycle would be a great addition.

This device works amazingly well. I was able to time my mags in five minutes.

Where has this tool been all my life? Cannot say enough good about it, great value and an unbeatable aid for timing mags.

This is a great tool for timing engines. Simple to use and reliable.

It does what it is supposed to and if you buy the one with the tweeter, it makes it very easy to know when those points are open. A great purchase!

Nice and light, easy to use. Worth the money. Works on P&W2800

Well constructed, easy to use, and dead on accurate. Virtually identical to the one offered by the manufacturer of my magneto at half the price. And it works on my old Harley mags.

worked perfectly out of the box. Read the instructions as it is not a continuity checker...

Q&A

Q: Will the dual mag synchronizers work if used on a single mag?

Per the supplier: Yes, they will work on a single mag.

Q: Will the dual mag synchronizers work if used on a single mag?

Per the supplier: Yes, they will work on a single mag.

Q: Will the single work on classic outboards?

This will only work if you have a breaker point ignition system. It will not work if you have a more modern electric system.

Q: When the plug is to fire for timing do the lights on the synchronizer go out or do they turn on?

The lights will go out when it fires.

Q: Is there a manual included with these INDUCTOR MAGNETO SYNCHRONIZERS?

Yes, these synchronizers include an instruction sheet in the box.

Q: Do you have recommended use instructions?

Per the manufacturer: The dual and single mag timers have operating instructions included with each timer. First time users sometimes do not read the instructions and erroneously assume that this timer will do the same thing as a different brand of timer. They sometimes think that they should get a sound indication by touching the ground lead (alligator clip) to the red or green lead. This again is an erroneous assumption on their part - based on their experience using a different make of Timer.

When I get an inquiry from someone who is having difficulty using the device, I do the following-
1) For Dual Synchronizers - I ask if both LED lights go on when the device switch is slid to the on position. If only one light goes on - there is a defect and the device should be returned to me. If no light goes on I ask that they replace the 9 volt battery and try again. With the single mag timer -only the LED labeled "Closed" should light up when the device is switched to "ON".

2) I ask them to attach the device to a working magneto. It's safest and best to do this on a bench with the magneto removed from the engine. They should clip the black ground wire to the magneto's casing and attaching either the red or green wire lead to the Magneto's "P" terminal. Then by rotating the Magneto's shaft they can expect to get the appropriate light and sound signals from the timing device. Sometimes they have a bad magneto and they need to try it on a second magneto

Often, I get inquiries from non-licensed mechanics who want to be walked through the entire timing procedure. I inform these individuals that this is a procedure that only licensed AP mechanics can legally perform.
