Question on grounding just occured to me

Recommended Posts

Simplicity314
I'm in the process of putting an engine in one of the 6008s I got (Thanks Kirk!) and a question occured to me: Why is there the heavy-gauge ground wire (that goes from the head on the vert. engines) to the frame? Isn't the engine grounded anyway since it's bolted directly to the frame, except for a few that have rubber mounts?? Thanks

That is the primary ground from the battery. The chassis is actually grounded through the mounting bolts, through the engine, to this wire. Since the starter is the major load from the battery, it is better to ground directly to the engine block than to pull the power through the chassis. The current path is shorter and flows through larger conducters, giving less resistance to current flow. You will probably find that the battery is not grounded to the chassis at any other point. Many tractors do the gounding this way, but sometimes both the engine and chassis are grounded directly to the battery.
