Is the pack grounded properly to the block?

Re: blows powerpacks 80 hp

sure looks like it is i beleive 3 ground wires on the corners, i just bought the used motor, ran 1 tank of gas thru it no problem, next time out 2 gallons later it fried, i replaced it with my spare pack , copied the wiring excatly how the original was,( maybe that was my mistake) same thing happened,( i did notice the fist pack that went bad looked new too) like it had just been replaced ill geta manual and double check the wires. my main concern is that no other electric components will cause this to happen,again .a bad ground connection can cause a working pack to go bad? is this the most common reason? theres a couple of other electri components right next to the power pack , should i change those too?
