I'm trying to restore my Dad's old tractor to working condition. Some time ago he had the tractor engine rebuilt and had it re-painted. The original key switch dad been replaced and a low amp push button switch was wired to the intake glow plug. This setup was wrong and the switch shorted out after only a few uses. My question is can I install a solinoid switch between the power source and the glow plug and use a another cheap push button to activate the solinoid? I don't mind pulling it off to start it, but, the Wife never seems available for this kind of chore when I need her. Thanks.
