Stator/Pulse Coil on Sportsman 90
#1
OPT, I'm getting the 150 ohms the manual calls for on the coil. But when checking with a Peak Reading Adapter I have 0 VDC. I'm turning the motor over with the kick starter. Also the stator ohm readings are all well above the 0.1 BK to Grd, 0.9 BK to RD and 0.5 BK to YE that is called for. I'm getting like 2.4 and 2.0 ohms. Looks like to me that I need to replace the stator and coil. The thing that had me sort of wondering was the correct ohms on the coil but not seeing the 5 VDC when turning the engine over.
Am I anywhere close to thinking right? Thank You for your time!!

Resistance is the first thing to check on stators because it's the easiest test and usually accurate but not entirely fool proof. Does have a cdi test that you can try but you really need the electric starter. CDI OUTPUT TEST USING PEAK READING ADAPTOR
Re-connect all CDI wires to stator wires. Disconnect CDI module wire from ignition coil primary terminal. Connect
one meter lead to engine ground and the other to the ignition coil primary wire leading from the CDI module. Crank
engine and check output of CDI wire to coil (130 DCV). Reconnect coil wire to CDI.
Output w/ Peak output tester
130 DCV
Average Output w/ Digital Voltmeter
20 DCV
