I bought a little used Generac # 052420, 13K home genny. I want to warm up the "oil pan" so it starts oiling as soon as it starts. It's got a 992 twin engine. I used a silicone heater pad against the bottom mounting plate under the engine and almost got a year out of the 100 watt heating pad. I have it hooked up to a Inkbird 308 thermostatic heater thermostat. It worked well for almost a year , then quit heating. I set it for 45 degree turn on and 55 degree shut off. Found the pad burned out. Replaced it with another similar and noticed a light whisp of smoke emanating from the heat pad area. I'm not crazy about this happening. Anyone got any ideas for heating my engine up? There's not enough room for a magnetic heater under the bottom engine plate. Thanks for any constructive input. Roy " The Deere dozer guy"
