Hiniker plow stalls engine.

[Duncan90si]

My Hiniker plow is acting up. Anytime I touch raise or angle on the controller it wants to stall the truck out and there is no movement of the blade. I replaced the grill plug on it because it was worn out and not making good connection. It worked fine for a few tries afterward, then started doing this. I didn't switch up any wires when replacing the plug. I checked all my connections under the hood and on the plow and they are clean and seem to be making good contact. I'm puzzled now. Any help guys?

What kind of truck, and how old is it? If you're testing the blade, repeatedly raising and lowering, and everything's going fine then starts acting up, I'm wondering how good your battery and alternator on the truck are. May not necessarily be the plow's fault, but a weak battery and/or alternator could cause a truck to stall when the battery gets depleted from running the plow.

On the flip side, depending on the condition of the motor on the plow, it may be drawing too much amperage, causing the battery to deplete much faster than it should, and the alternator cant keep up.

Lastly, check the truck wiring, John posted in this thread (http://www.letstalksnow.com/forums/showthread.php?t=19077) yesterday about a truck that had the charge lead off the alternator connected to the neg terminal on the battery. :eek:

I'd start be having the alternator and battery on the truck tested and go from there...

Like Wizard said, check your battery/ies and alternator. Also check you connections at the motor/battery/ies. Especially your ground any high resistance and things are just not gonna work right.

Like mentioned just check your battery connections, someitmes when they install extra stuff on the battery terminals, they tend to losen up. The plow is probabbly fine, but if there is a weak connection the juice from the alternator is going to the plow and dropping your volts well below the minimum the truck needs to stay running. Double check your pump motor ground, and maybe take a jumper cable and make a temporary ground to the motor and then try it. I had a bad ground once and it drew so much juice the truck would stall out.

You got it. I was testing the pump motor with jumper cables and found that the main ground was bad at the grill plug. It wasn't corroded or anything but for some stupid reason wasn't making good enough contact. I cleaned up the plug and put some dielectric grease in there and bingo!

Thanks for the input and advice guys.
