My 357xp doesn't want to start and in the process of troubleshooting it I measured the coil resistance. The results sound strange to me, but before I throw away $60 on a new coil + shipping I'd like to be fairly sure the coil I have is worth replacing.
The Husky service manual claims the primary resistance should be 0.2 ohms, mine's reading 135. The secondary resistance isn't spec'd in the Husky manual, but is 1600 ohms on my coil. I think a typical winding ratio on a good coil is in the thousands isn't it?? My ratio is about 12, which seems like the coil is shot. However, when I talked to a guy at Bailey's today he seemed to think he's measured around 120 ohms on the primary before on perfectly good coils, so he wasn't sure it was really bad.
So can anyone give me any advice here as to what the proper coil resistance should be.
According to Bailey's they use the same coil on everything from the Husqvarna: 334, 335, 336, 338, 339, 340, 345, 346, 350, 351, 353, 357, 359, 362, 365, 371, 372, 385, 390, 570, 575
If anybody has one of these Huskies already apart, or if you feel like removing the starter cover and measuring it, I'd appreciate it.
thanks everyone.
