Hi Pockets

Hey Gang,
I'm in the middle of my second winter with this truck. This is an 03 cummins in an 01 F250. Cold starts are getting tougher and I don't think the intake heater is coming on. Can anyone tell me how you wired your grid heaters? Are you letting the ECM handle the heat cycle? Or, did you put a manual switch somewhere on the dash? I'm in the Denver area and we are seeing temps in the single digits.
Thanks for helping me with this one.

Just install a circulating block heater?

Hi Pockets

It starts fine when it is plugged in. If it is out in the cold and not plugged in, it will not start without a shot of ether.

What was telling the heaters to come on? I mean, the Dodge computer or the Ford one?

I put a pair of LED's hooked into the power to the heater on mine to know when they were actually on versus the WTS light. That might be something to consider. If I did a conversion, I would just have a push button switch to bring in the solenoids, but that's me being simple.

Hi Pockets

I think the Dodge ECM is controlling the grid heater.
I'll have to check when I finally warms up.

Invest in a clamp style multimeter then you can measure the amp draw from the grid heater.
I would say your heater isn't working, you would have had a big problem with the either otherwise.
