    Ok I have an older RT2 Boss V on this Chevy 3500 w/350.
    When I raise the plow it puts a serious draw on the electrical system. So, I checked the battery. Load tested fine, got the high output alternator, installed it now I have massive charging. awesome...Raise plow, serious draw.....So I fabricate a battery box underneath the bed...this is gonna do it, link it all together, have some serious cranking power! Raise the plow and put in scoop and I can Kill the engine....wtf? So, I took all the grounds off and scrubbed them clean.....nothing changed? Lets here some ideas... Im thinking worn bushings in plow motor or the solenoid is toast?

    Is there like a volt test I could do on it? See how much its drawing and what the normal range was?

    You would need to test amps, not volts. The ammeter (or multimeter or gauge) gets connected in series with the load. You'd need one that can measure a whole lot of amps.

    I would look at engine grounds first (unless those are the grounds you said you already scrubbed clean). Often failures are easily visible, like a broken or severely corroded cable.

    In my experience I've never ever ever had a motor not function properly because of a bad ground. People always say "check the ground" it's never the ground. It's usually the electric motor. Bet you it's the motor for sure. Sounds like a motor drawing too many amps.

    I had a hoist motor stall the engine on my 350 and thought the same as you. It turned out it was the engine ground. Nearest I can figure it was grounding itself through the hoist ground and throwing power to the hoist killed the engine. I replaced the engine ground and everything was good. It was the same symptoms...just saying,.... Check that ground first.

    Ok thanks, I've cleaned and scrubbed all the connections and grounds and added another ground from engine to frame....I think it may have helped a tiny tiny bit. But still draws the engine to near stall.
