Boy did this take an abrupt left turn...
when the motor is spinning, you creat a static discharge which gets let out into the coolant hence the reason why coolant is NEVER a lifetime fill. The static discharge let off by the engine has to go somewhere hence the ground wire I stated connects the motor/tranny to the chassis/unibody of the car. Now if you modify your car to rev faster then before, a larger wire maybe 0 gauge vs 4 gauge is what I have been told is required/recommended. That's why I ask if you guys know anything about this or why my licensed transmission guy/mechanic mentioned this to me. I also stated that the connection look a little corroded so a good start would be to clean up the connections for a better ground contact
To put it very simply and bluntly, you've had smoke blown up your ass by someone who saw you as either:
A- a potential source of a laugh for the day;
B- a source of additional income, for work that isn't necessary; or
C- a target for abuse.
I'm an FAA-licensed Airframe & Powerplant mechanic. I've been working on helicopters since 1993, both military and civilian. Helicopters are well-known generators of static electricity, due to the nature of their rotor systems moving through the air at high speeds. While I was in the Marine Corps, I worked and flew on the CH-53E Super Stallion, which has been documented to generate over 25,000 volts of static electricity through it's 79ft diameter, 7-bladed main rotor system.
Look closely at the following picture. That stainless steel wire, touching the ground, between the two tires? That's where that 25kV+ of static electricity goes to ground on the CH-53E helicopter. Note how small it is (1/8" diameter, to be precise)...
- Your TDI WILL NEVER generate as much static electricity as a full-scale helicopter of ANY size.
- You don't need a bigger grounding cable between your engine and body
because of static electricity.
- You
may need a
new grounding cable due to corrosion issues.
