    I have a Unimount plow on a 1998 Chevy 2500 with 350 V-8 gas engine. About a month ago it began to stall out the engine every time I try to use it. I hooked up another Unimount plow that I know has NO problems. It does the same thing. Anybody have any idea what is the problem here? I also tried a new relay, no change.

    Check the voltage on the battery. Should be between 13-14 votls. Check the alternator too, should be in the 14 range as well. It may be poorly grounded, so check wires and see if the terminals are tight on the batterty

    I am sorry I forgot to say I installed a new battery and alternator. Grounds are good. Thanks.

    i had a 2003 chevy 2500hd 6.0 V8 with a boss 8.6 straight blade it also did that after putting in a new battery and alternator it still stalled. I took it in to two chevy dealers and neither one had a answer for me. After almost a grand i sold the truck. Does your truck only stall with the headlights on? that was the only time mine did

    You said that your grounds are good but exactly which ones/how many did you check? Later model trucks actually have many grounding points on them and they all need to have a good connection,not just the one at the battery. Also, did you replace the battery and alternator in an attenpt to fix this problem or did this problem start AFTER your changed them?
