Electrical help please.

On a 725 how do I know if the electircal part at the other end of the spark plug wire is working correctly ? It seems as though things are getting worse for me and I will have to take a look at that portion of the electrical system. When I am there how will I know If it is running correctly? Thnx for any help Herm

Do you have the briggs repair manual? There are continuity and resistance tests.

If you have a multi-meter,set on the Ohm setting,connect one lead to the plug wire end and the other to the body of the coil,it should read between 2500 and 5000,if its below 2500,its shorted out--no good,and if its over 5000 its an open circuit and again ,no good.i don't know how to test the condenser,some one else may.have you checked the gap between the flywheel and armature ?

Its not to likely that your coil is bad,if i were you i'd replace the condenser--get a genuine B&S one ,i tryed an odd brand one and that mistake cost me some time , it was bad right out of the box..but this is learn by doing.

What is the "Briggs Repair Manual" that is talked about in here? I went to the local library and the ones they had did not go back that far. I have the "Large Frame" book and there isnt much in there about this. Thnx

Mick14, it runs for about 25-30 minutes then the machine quits until it cools down, then it runs.

Thnx Maynard, appreciate the help, pics and all :)

Its very possible that the condenser is being effected by the engine heat,the easy way to test that is to change it,under $10.00, if your fuel system checks out o.k.,this would be a good next step.

Mick14 do you mean the condenser near the points ? Thnx for the help

[Mick14 0]

Yes,the little beer can thing,worth a try.I'm thinking now that i should change the points and condenser in my 725.i have no idea how old they are.
