haha!! I have seen the surprises when brake cleaner is sprayed into a 2 liter Yanmar engine on a thermo- king reefer! Boom boom and did I say boom haha!

The engine manifold heater they are referring to is a grid heater just like on cummins engines. It is a heated element placed into the air intake to preheat the incoming air. They work well when they are working correctly. This is NOT to be confused with a thermo-start in older Yanmar engines that makes a flame inside the intake manifold off diesel fuel from the tank.

Grid heaters and glow plugs do draw a lot of amperage off the battery. Before attempting to start your tractor you could put it on a trickle charger overnight or a battery charger just before using your grid heater. This will help top off the battery and may make a more successful cold start. This is strongly recommended if you do have a weak battery.

Check your battery connections and clean. All connections, grounds and even connections at the starter need to be shiney clean. Ground and starter connections can be coated in spray paint and battery connections can be coated in battery protector or dielectric grease.

Is the manifold heater yellow light suppose to shut off when it get hot enough,because it doesn't. Maybe I'm not holding it in long enough,less than a minute. ( I get impatient ) it got a new die hard on a trickle but still cranks a long time. Hopefully we will get some warmer weather before I need it again. I would like to thank everybody for there comments, I'm a new member and I find everybody so friendly. Thank you.

Cummins engines are automatically timed. There is a sensor that tells how cold it is outside and the timer starts. I believe the longest setting is 40 seconds.

Grid heaters last a long time. On your John Deere to my knowledge it is a manual controlled item. 30 to 40 seconds below zero is easily expected.

Try this : plug your battery into a trickle charger over night, or into a charger/ jumper cables just before use to top off the battery, hold the key for the manifold heater for 30 or 40 seconds, crank the engine for 10 maybe 15 seconds. Just after you stop cranking the engine go back to preheating for 10 or 25 seconds, after preheating crank again for 20 or 25 seconds.

If I knew your engine I would know exactly what has to be done to get everything going. But I do not. That is just something I roughly do on any engine cold start I'm not familiar with. I Never crank a starter longer than needed. For most starters over 30 seconds can be considered harsh on them without any cool down time

I forgot all about the pre heater. The light does not go off from it getting warm enough. I owned a 4500 for several years, but it's been a few since I sold it. My bad for not remembering it and I apologize, but knew I was right about it not having glow plugs. The manual should say to hold the key in for about 30 seconds normally and a bit longer as needed when extremely cold.
