Testing B&S Coil
A blade trimmer that has worked flawlessly for years suddenly stopped working and gets no spark from the coil lead.
The 2 HP B&S engine is a 60102 and the coil is exactly like this one:
There are three leads: One to the spark plug, one to the points and a twisted pair of magnet wire from the coil going to ground.
The magnet seems extremely strong.
I want to test the coil and see if it's the problem, but the information I've found online so far is 180Ã¯Â¿Â½ contradictory.
DC resistance between the spark plug cable and ground is a steady 3000 Ohms. Depending on who you believe, this means either it's perfectly good or it's stone dead. Helpful, huh? Presumably, they're talking about different coils, but they don't clarify.
To get to the lead going to the points, I have to pull the flywheel, which I'd rather not do if I don't have to.
Any suggestions as to how to test this coil and where to go from here?
If the above info indicates that this is indeed a dead coil, is it possible to retrofit a new electronic ignition coil to this model?
Here is a link that might be useful: Example of coil
