I have heard of disconnecting the grid heater, where do I unplug?

Also do I need the heater in 15-20 degree weather to start(if i dont mind the smoke?)

 

how come?

are you looking to flow more air? the flow difference between having them or not isnt seen until you are pushing large HPs (if even then). i would invest your time/money elsewhere.

just my opinion.

and my truck seems to like them at 15*-20*, otherwise its a little too chilly for mine.

 

mine started fine at 3 to 5 degrees without being plugged in a few times last winter.

 

Regardless of why you want to unplug them, the relays are fed directly from the battery---two black wires, on mine anyway. They are about 8-10 gauge. Mine are unhooked so far. We'll see when it gets cold. Sure smokes more on these chilly fall mornings.

that does not make much since to me, what is the advantage??

 

If you are worried about deep cycling the battery, just start it right away. Then the heaters will kick in and warm it up fast. You will carbon the heck out of the engine starting it cold and letting it idle. 'Course one good hit from Wanna's water injection under hot boost will clean all of that out!

 

To disable the grids, just pull one small wire (either one, doesn't matter) off each relay. They are just push-on connectors, so it's very quick and easy.

The first year I had my truck the grids were dead (melted relays). It started fine all winter, it saw temps as low as 17 unplugged. I fixed it because it was really putrid once I put the POD's in.

I think that if I had to start one in cold weather with a marginal battery, I would disable the grids first. Mine always lit right off, never heard it crank.

 

I unhook mine at both connections at the relays on the fender liner, and on the heaters themselves on top the intake. I don't care for them. Too much of a drain on the electrical system. Especially short trips in cold weather. Grids be cycling all the way to and from work, never giving your wimpy:laugh: battery a chance to fully charge. Over a period of time you end up with that NO START one morning... Don't forget there is a post heat cycling. Big battery, good alternator, starter, air tight fuel system, no need for grid heaters. Just there to cut down on cold weather emissions.

 

''Just there to cut down on cold weather emissions.''

Exactly. Many folks think (flasely) that the grid heaters are a cold start aid. It's important to point out that they are only on b5.9's installed in Dodge trucks...hmmm.

I think it really helps warm the engine up fast. Without it, and with POD's as Dave said, my truck turns day into night, like the fires of Kuwait! With the heaters my engine is warm enough to burn properly in a very short time. Get an Optima! I have deep cycled mine more times than I'd like to admit while diagnosing a charging issue (and the occasional dome light left on) and it still works every time.

 

WRONG!! We have them in tractors too, and they are for starting and less warmup smoke!

When I bought my truck some of the trigger connectors were off. If looking down from the drivers side what is the correct connection sequence from left to right. I looked in a Haynes Manual and the colors didn't match Thanks.

 

Oops, my bad. My mouth has really been tasting like boot leather this week...better do more reading and less posting, hehe. Thanks for the correction.

We need pics for proof . Special order? On a 5.9 Cummins? Either way, the truck should start FINE without them .

 

If I try to start my truck when the temps in the low teens or below without the heaters it misses really bad and runs like crap for a while. I used the heaters this morning becuase it was 36 when I started the truck.
