    Had the same problem .You better get that battery replaced.It would show a charge but one of the cells went bad in it.I replaced it with a beefed up one and no problem since.And if you have your gauges go flat, your plow and everything will keep working it's just running off the battery I believe it fuse #46 at least in my 02 F250 ,and it's a mini fuse.

    i will have the battery checked but the gages do not go flat with the plow running. the volt meter does drop a little but not much the other thing i noticed when hooking the plow up i had the truck and plow about 1/2 in apart sparks came between the plow mount and plow frame is this a bad ground on the plow it self if so ware to look? any help?

    You have a poor ground path between the truck and plow. A poor ground will cause the plow to pull an excessive amount of power...and on a Ford the first thing it affects that the operator will notice is the radio. :nod:

    Never hurts to have the battery checked as well if it has any age on it.

    is the poor ground path between the truck and plow in the main ground in the harness?

    Could be anywhere between the two. At the connector plug itself, where the ground cable is attached on the plow, or right at the battery itself. Need to go over them all.

    If it's not readably noticable replace the entire ground, they break and corrode inside the cover and just eat up current.

    B&B, the poor ground and the sparks flying seems to be a common theme with the BOSS plows. Is it a common mistake on the installation, if so what is it? Or is it something to do with the BOSS specifically?

    my 9.2 poly v has a little bit of sparking when you hook it up but i dont notice any abnormal power draws with heater on, radio on, cb on, 2 strobe beacons and back up lights on...

    its an rt3 btw

    b&b would you still suggest i go over all grounds or is a little bit somewhat acceptable? :drinkup:

    It's actually the whole reason Boss went to the two terminal motors...helps eliminate that very common issue with the poor grounding through the motor body or the light tower (as the older one were). With the two terminal motor you have a direct ground path directly to the motor internals. If you find sparking between the truck and plow with the two terminal motor then you have a ground issue on the truck side (batt terminals usually) or in the power cable connector body.
