It was a brisk 48 degrees when I left the house this morning. While idling during warmup I noticed the truck running a little different and the headlights going from bright to dim over and over again. I also noticed the wait to start light stayed on for about 10 seconds instead of the usual 4 seconds. First time experience for me. ;D

Grid heaters.....check. ;D

 

Mine are working well too. With temperatures getting cooler here in MD, mine have come on a few times in the morning.

 

30F here this morning. I also noticed my headlights dimming and getting brighter after startup. I also noticed my heater fan slowing down and speeding up after start up. Someone has posted that this is a result of the grid heaters operating on cold mornings. As the truck warms up the dimming stops. I guess the current draw is normal as many posters have writte about it.

 

It's also mentioned in the owner's manual.

Mine cycled for the first time here in SW Arkansas this morning. I didn't realize they kept working after the engine started so it took a few seconds to figure out what the clicking noise was.

 

Wait 'till Hoss has the truck idling first thing on a cold morning (which he might never see in Texas :) goes back into the house for his cuppa coffee, comes back out and it's idling higher! ;D

 

My high idling stick takes care of that.

 

Grid heater? What is that needed for? Should I have one or go get one?

77 degrees today, blue skies, and the snook are biting - - better come home, Spots.

 

Somehow I think you need one less than I do.

 

I'm starting to get deja vu from last year about this time when hottubbob was showing off his polkadot bathing suit to all us canucks!

 

Just got back from The Bahamas. Saw a few rigs like ours, but I doubt any of them will need to be plugged in.

I attended college in Gunnison, Colorado, and with temperatures well below zero (I remember one morning it was -35), my headbolt heater was the only reason my 1950 Ford started right up, and was blowing hot air while other vehicles around town couldn't even turn over.

Where I live now the temperature can also drop below zero, so am sort of anxious to see how the heater on my 2003 works out.
