    My guess is its because you only have one battery and you have not done anything with the alternator. After moving the plow up and down a few times it may take a few seconds for the electrical system to catch up with itself. Too much draw on a stock non plow preped truck

    voltage drop

    I have had this happen to me last year and this year also. I'll be driving to a job and the chime goes off. Look down and voltage has dropped (3-4 sec.) then back to normal. Plow is not in use, lights are off, heater & radio on etc...
    I have asked people what this is from.... still no idea. I had everything checked for a bad ground... nothing.

    I have an 05 2500 Hemi, and it does the same thing when operating the plow.
    Been to the dealer, and the folks that installed the plow. All systems check OK, been doing this since new, plow must draw too much for the alternator, and sets off the alarm. (I have the plow prep package)
    Hasn't done any harm that I can see, been doing it since 12/04 when I bought the truck and plow.

    I had the larger alternator, but upgraded from the factory battery to an Optima Battery. The OEM was rated @ ~ 600CCA & 38 AH to an Optima Red Top @ ~ 800CCA & 50 AH. Its still not enough when I add the Plow, Strobes, Light Bar (with 4 Lights), Sub & Amp :) I'll probably be upgrading to a Odyssey 2150 which is 1090 CCA & 100 AH. Its almost like having the capacity of 2 Optima Batteries!

    Sometimes, we just draw alot of amps!

    My 2008 ram 1500 was doing the same thing. was doing it even before the plow.

    Just had it checked out at a local elec shop and my 136amp was only putting out 50amps at full load.Checked the diodes and they were ok,they said the windings could be bad.Going to the dealer monday.

    Maybe chrysler is giving us junk altenators so they can save moneypayup

    My 2003 2500 Hemi is doing the same thing. I am finally noticing it due to the white-out snow conditions we are having. The defroster is on high, headlights, warning lights, and heated mirrors all on. The voltage goes to 0 and the "Check gauges" light and bell comes on. It goes off after a few seconds. I will be looking to upgrade the electrical system over the summer.
