1 Usually less than 15 minutes. Longer operation at this temperature may shorten the life of the unit.
2 Voltage to the coil must be limited such that coil primary current falls within safe operating parameters for the coil. At no time should coil voltage be such that primary current exceeds 6 amps continuous.
3 For 12 volt systems with 3-ohms coil primary resistance.
4 Short term overload protection only. Not intended to replace proper coil primary resistance.
