Question: why are my ohms at 0?
Answer: Any coil or atty that fails to connect will give a reading 0f 9.9 or an error indication on a mod. THIS IS VITALLY IMPORTANT! IF ANY COIL READS 0.0 DO NOT USE IT... 0.0 MEANS ZERO OHMS THAT IS A SHORT CIRCUIT, BATTERIES EXPLODE WHEN CONNECTED TO SHORT CIRCUITS!!!!!!!!!!!!
