How To Bench Test Briggs Stratton Starter

Rob gives a quick tuturial on how to bench test your starter to see if it is operating properly. NOTE: Every starter has a different method. This is out of a cushman groomsmaster sand rake. 16hp Briggs Stratton , V-Twin motor.

This was simple and to the point. You just gave me a test to try. I'm new to simple electrical issues so this was up my alley! Thanks!

Howdy Rob, I had an almost new, 5 yr old, Briggs powered 20 hp single ohv 46 in cut craftsman tractor given to me . It just needed battery and cable replaced . Ran good, but variable pulley drive was going real slow . I replaced belts, fixed variable pulley that was sticking . When testing the pulley operation I had the tractor supported on stands so I could engage and see drive operation . I was starting it and one time the engine stalled out cause the pulley wrapped around itself binding engine up! I unbound it and now starter won't turn engine over, its like too much compression .I take spark plug out and motor cranks right over with good compression . I checked and adjusted valves., they were where they needed to be ! The starter never had an issue before this . I have heard this motor has a compression release, that was gonna be my next check, but I was gonna look and see if my engine had spun the key and is out of time . Is there way to do a test to see if starter is strong enough, amp draw test or such ? I am beginning to think the rapidly stopping engine may have sheared flywheel key ! Any thoughts on this ? Advice would be appreciated! Ps, I think this variable pulley drive system sucks .My old craftsman with 6 speed never ever gave me problem . Just push in clutch & change gear !

After losing a few starter gears I noticed the whole armature shaft can move up and engage the gear when it should not. The starter itself turns fine but the gear stays up because of this shaft linear play. I assume a key has been displaced to allow the shaft movement. I won't know until I open it up I guess.

I would test mine with one of the many chargers I have. What amperage would you suggest? Thanks!!

[stevemlejnek]

What if it spins but the gear doesn't "hop up" to engage the flywheel in a bench test? Would that be a failed test? Thank you.

On these starters is there sopose to be continuity from the bracket mount and the power terminal?

[antijordan]

Do you know by how to remove the gear?

[danlford]

So if the starter does nothing at all it's bad? Correct?

[jimlundstrom]

Are the starters ever tested under load to see if they can turn the motor properly?

[mikeharris]

This test is not always accurate, sometimes they will spin without resistance. But thanks for helping the people you did help.

you always should connect positive first then negative, less chance of an arc, spark which you would not want around a lead acid battery that might be leaking hydrogen gas. actually if it were me. I would hook the jumpers to the battery, connect the negative to the frame of the starter then tap the positive lead with the positive jumper .

Best not to "put a lot of pressure on it" if it is held in a vise as he has done. Inside of that 'can' are molded (brittle) ceramic magnets. Too much pressure in the 'can' could break them loos or crack them - they will not bend!. Best to clamp the mounting bracket in your vice = on that ou may exert some pressure.
