Multimeter question
Hi there,
I have a (old) Gunsons multimeter, and would like to know if anyone knows how to attach it for use as a tacho. The instructions show a diagram with the meter connected to a car, one terminal to ground and another to the coil securing point, but not sure where to connect it on a GL1100 with two coils and no obvious point. (can't remember the colours of the meters cables, but can look that up)!
If anyone has a similar meter if not the exact one, sure the principle will be the same.

Re: Multimeter question
I have a "Engine Analyzer" that looks similar. I put the ground to the battery ground and the red to one of the bullet connectors where the points/dyna hook into the main harness on a 1000. Because of the wasted spark system mine reads half scale, so when running 1100 rpm I get 550 on my meter but it works. If you can find a way to touch any of the trigger wires from the timing module it should work, it just needs to see the pulses.

Re: Multimeter question
Thanks for that, but a little confused as the 1100 doesn't have points as I'm sure you know. Maybe someone else knows where to hook up the second wire?

Re: Multimeter question
I do not know 1100 wiring well enough to provide that info. Maybe where the coils plug into the harness??

Re: Multimeter question
Try hooking it to the wire, on the primary of one coil, where that wire goes to the ignition (trigger wire).

Re: Multimeter question
And play with the "Range" and "Cylinder" switches. Try low range and 2 cylinders first. I never have figured out how to use one of those for accuracy on a 4 cylinder, two coil, wasted spark ignition. That much math hurts my head. You have to realize that the particular tool was used on a distributor ignition. That means for every two revolutions of the crank the distributor would make one full turn. So with an 8 cylinder engine the rpm readout would be two RPM, of the crank, for every 8 pulses it counted.

Re: Multimeter question
Set it on 8 cylinders and it will read correctly for our bikes.

Re: Multimeter question
The 8 cylinder setting will read double on a 4 cylinder motor - with a distributor. Since the meter will read 1/2 of what it should on our GoldWings, due to the double spark, the 8 setting should give a correct reading. Mine does, but it is from the '70s.
