YES *******
If it's loose, it's a poor ground or no ground at all. Electricity will always take the path of least resistance, so when a circuit requires the path provide by your old ground, it will use the new one instead...either completely, or a small current may flow through the old ground wire.
Alternators are generally grounded through the alternator body to the engine block or head through the attaching bolts.On many cars I've owned I add a ground strap from the alternator body to the block to eliminate any chance of poor connections throught the mounting bracket.
This might mean the ground is isolated from the case of the alternator. In a normal application, the case of the alternator is the ground connection and being bolted to the engine block via a metal bracket, the grounded case of the alternator is electrically connected to the ground lead of the battery which is also connected to the engine block. An isolated ground might indicate the alternator ground is electrically insulated from the alternator case.
it depends if you want to risk it then yes. If not then no. Usually u would just fire of the ground to not damage the gun
The negative battery cable is grounded to the battery tray and engine, close to the starter on the block. It's not a real great ground system but, its all you need if you can keep the battery tray connection clean.
The 1993 Chevy S 10 Blazer 4.3 liter engine temperature sensor can be grounded to the engine block. You can use the temperature sensor retaining bolts to ground the temperature sensor.
Interesting question..glad you ask......The only ground on the engine is the negative cable is attached to the negative post on the battery, then the battery tray, then it is bolted to the block. The connection on the batt. tray sometimes corrodes and is not the best ground. That can be solved by adding your own ground...and then, not to worry.
In Electronics, a "grounded" object is one that is connected to the ground through a connection that allows electricity to flow the ground. In some circumstances, for instance in a car, the rubber wheels make the car isolated from the ground, but electrically a large piece of metal can be called the ground, like the engine block or body of the car. ground in electronics is somtimes spelled GND.
Drivers Side Grounded to the block.
Since a ground block is not well insulated, there's always the danger of a short.
Connect the positive clip of the charger onto the positive post of the dead battery. If the battery is located inside of a vehicle, connect the positive charger clip to a grounded surface--like an engine block--on the vehicle.
By using ur hands and brains
the oxygen sensor is grounded when you thread it into the exhaust manifold the oxygen sensor should have only 1 wire it should be purple the didnt start putting 2 or 4 wire sensors in until the early 90's there should be a ground from the battery to the block
