No spark

[srwven]

Tractor quit yesterday. Pushed it into garage. No spark. Changed plug, condenser, cleaned and checked point gap. Still no spark. Swapped condenser with one I know works, nada. Tractor is a 916 transplanted with a briggs starter generator. Started checking wiring. Everything seems ok. PO had scrapped all the PTO safety switches-there was a ball of them under the gas tank but nothing connected to the key switch. Thought the wire from the flywheel was a bit brittle but I get continuity from the kill wire from the key to the condenser wire. Voltage regulator had also come loose, tightened that back up, still nothing. Any ideas?

Completely remove the kill wire from the points and condenser and try that.

Thanks Dan. Removed the kill switch from the condenser, no spark. Armature bad?

Steve,

Have you pulled the engine out of the tractor (yet)? The cast iron (10-16 HP) single Briggs engines are famous for being "free hosts" to mouse condo's underneath the blower housing and them chewing on the coil wires. Also, this may be a case of a partially sheared flywheel key. Assuming there is no damage to the coil & wires, these (coils) rarely fail.

check ammeter wires

Well, turns out 1 ground wire from the ammeter broke off. You would think they would make these wires a little heavier gauge:(. New one is in and all is good. Now I'll just solder the old one and have a spare 8D

At least your up and running!
