tach on vangard

Ellis Kinney · Aug 7, 2017

I recently purchased a new piece of equipment with a vangard v-twin 35 horse engine. I really want a tach for it. I have no clue how to hook it up and would
like some information. What I have seen on you tube is not very informative. I would like something 3 or 4 inches in dia., but will settle for a 2 incher if
I have to. Recommendations ? Thanks, Ellis

Briggs and Stratton (and probably some others) offers a tiny tach that is about 1" x 3" and has an adhesive back. It also has a pickup wire that you just wrap at least 4 turns around one of the sparkplug wires.
Of course, this is mainly counting sparks, so its probably only real accurate at about 3400-3600 rpm.

A lot of the commercial mowers use an oil pressure switch to ground their hour meters. Of course, you will have to consult a manual on your engine to find the oil pressure port. And come up with a pressure switch that grounds when it senses pressure. They wire fairly simply, a positive wire to the hour meter that is hot only when the switch is 'on' and a wire from the other tab on the meter to the oil pressure switch.

Some other commercial mowers only run the hour meter when the pto is on and the blades are turning. This does only count hours when you are actually doing work, but the downside is if the equipment is allowed to run with no load on it for long periods of time.

Hi as the other poster said the tiny tach is very simple to install they are acurrate and have a hourmeter feature and are pretty reasonable on cost but they are not large.

I got a 4 inch round tach and had it put on my golf cart literature says it can be set for one to ten cylinders, wraps on plug wire for signal.

Rather then keeping it a secret how about giving the guy a hint as to what it is and where to get it sounds like its what he's looking for. GB in MN

This is addressed Mr kinney and to MNGB, as long as Mr. MNGB is acting as a secretary. I thought if Mr.Kinney was serious about his inquiry he would have asked himself,any way,the one I got Is Equus 8068, my error is it will work on 1-12 cylinders.

Just purchased a similar tachometer can not get the correct rpm read out. Instructions say to wrap the wire 5 turns around the plug wire. Does it mater if you coil the excess sensing lead out of the way? Appreciate any suggestions.

Thank you
