Truck stalls while running air bag compressor...

[rt_hawk]

My truck is stalling when I run my air bag compressor to fill up my bags...anyone else experience this?? I don't think it happens when I'm going down the road, just when I'm idling and not moving...could the compressor throw off a frequency that messes with the cps, idm or ecu? Or fuel pump maybe? Anybody have a idea? I also have a impulse (napa brand) brake controller and a dp-tuner f5 if that helps...

I am going to have to go with the DP. There is a known issue with HID's that cause a DP tuner to kill the truck, perhaps your compressor is doing the same. Try putting a coupple of ferrite choke's on the line from the chip to the switch box, only a coupple of bucks from rat shack.

I have never had a issue with my DP and compressor but it is a possability. Also, check your voltage with a meter. Perhaps you have weak batteries/alternator and the voltage drop is killing it. Also, where is the compressor getting it's power from, could be sharing a line with something that has too large of a fuse and the voltage drop is killing it.

My batteries are brand new 1000 amp jobbers, replaced last winter, they are directly hooked to the drivers side battery with a 25 amp fuse. So the alternator may be pooping out on me...will the ferrite chokes help with the radio in my truck stinking?

Those seem pricey, I'm guessing a 140 amp w/ a single HD rectifier would have me covered? What does everyone else go with?

Well, leaning more towards the alternator not pumping out enough...after the truck is running for a while it takes longer for the pump running to stall the truck...how big of alternator from that link do I need? And what's the difference between the types of rectifiers?

Also I put a ferrite choke on my dp cable, works wonders for the radio, otherwise, nothing else...Truck still stalls, how much of a voltage drop will cause a stall?
