Delete Me - 2024-05-28 Coil Bench Testing

Installed new YellowSquare ignition coils. Bike still didn't run good.

Time to bench test the coils. Search Google. Find this. Ez pz.

1. Batt + to coil +
2. Coil neg to switch to batt neg
3. Ground spark plug
4. Hi tension lead to sparkplug cap
5. Open the switch, primary field collapses, induces hi voltge in secondary, discharges through plug.
6. But. It doesn't work. No spark. Borrow two auto ignition coils. No spark. Test old Martek coils off KZ1300. These coils had the bike running. But no spark on the bench.

WTFO? Not likely all coils are bad. Must be test set up. 

1. Check all wires for continuity
2. Check plug resistance
3. Check switch
4. Everything checked out SAT
