Mertz Posted September 27, 2022 Report Share Posted September 27, 2022 I tested the 6v firewall mounted coil that I would like to use because the way it connects to the key. The primary coil reading is 2.5 ohms which I believe it okay for a non ballast resister vehicle. The secondary reads 3.5k. On a 12v coil that should be between 11k-15k. Most are much less around 9k. Is 3.5k normal for a 6v coil or is the secondary non voltage specific? Quote Link to comment Share on other sites More sharing options...
