I've had two people bring me trucks recently that had bad ground issues....
both had ground cables direct from the battery to that bolt on the exhaust manifold...

Both had burned up the connection crimping and one had been subsequently been soldered,,,and the solder had melted out again from the heat...

I simply replaced the ground cables, attached them to the alternator bracket, added two more grounds engine to chassis and cab to chassis, and both are now working fine...

You can never have enough grounds....
