You should run a dedicated cable back to the battery.

The main reason for doing so would be to ensure the cable capacity for the inverter. If you have the equivalent of 2ga cable at the battery post, and your inverter wants to use 100 amps (1200 watts), you have exceeded the capacity of that cable, which also serves the rest of the vehicle electric. In the same scenario, lets say that the frame of the vehicle has a total resistance of .1 ohms as seen by the inverter. Pass 100 amps through that resistance, and you now have a voltage drop of E=I*R = E=100*.1 = 10 volts. The inverter isn't going to tolerate that for long, and it may also cause havoc with other electronic devices as well. Your cable connections will have a lower bulk resistance, usually so low that it becomes difficult to measure accurately with a meter.

99 victory v92 I'm installing a new battery but am confused on which one is the ground wire. .can someone please help .Which wire is the ground?thx...jenna

On most systems, red is positive, and black is negative/ground. An ohmmeter could verify the black wire is ground by showing continuity to the frame or engine. It appears you have two black on the right and one red on the left. You can blow up the battery if you run one ground to positive and one to negative; running an extra to negative won't hurt, it just won't let some part of the system operate, probably the electric starter. If that's an extra red wire in the top center, put both red to positive terminal (+) and both black to negative (-).

Ford 1100 tractor diesel 5 port ignition switch with glow plug git a new one need help wiring it what cable go were Need a diagram if possible

Are the glow plugs single or dual wire if they are twin or dual wire one wire is positive and one is negative. I will base this on twin wire
I hope it is a negative earth system as I won't bother with positive earth instructions at this stage.
Get a multi-meter that has alligator clips on the cables attach black to a good ground then with the solenoid power wire removed on the starter (so it wont crank) get someone to hold the ignition switch in the on position, then test each pair of wires one will show voltage this is the positive one (mark each positive wire) now release the starter switch and change the multi-meter to ohms test the wires that did not show as active they should show good low resistance (hopefully 0) connection. now you can reinstall the glow plugs making sure positive on the glow plugs is paired with active positive wires that were marked then attach ground wires to the glow plugs.
Reattach the solenoid power wire and try starting it

1988 Dodge d100 my lights are flickering

It's a battery or ground problem. You mean all of them, headlights, dash lights, or what? The flickering is often caused by a corroded or deteriorated ground point for the lights, less common is a hot wire connection that is loose or not contacted well. Your headlights and front park lamps and any side marker lamps, I think they would all have a common ground, or maybe each side has it's own ground up front there. I'll try to find a wiring diagram for what you need, in the meantime, take off first the negative of the battery and then the positive post (for safety, always remove the negative first and reconnect negative last), clean both battery posts and the end of cables or the clamps that go on the posts. Any corrosion, green or white colored, is not good, and can lead to serious resistance in the connection, and hinder the electrical system. Those connections must be clean and tight, remember positive hooked up first, then deal with the negative post. Your truck is old, subject to rust, better check all your ground connections. The original negative cable had a large ground to the engine block and a smaller wire ground to the body, somewhere grounded in front of the battery to the frame. If rust is an issue, you can always find a better ground point-to clean metal free of paint.

If you know all this and you know the battery connections are clean and tight, then look for the ground point for the flickering lights in question. If you have a voltmeter it is almost essential to the testing or checking of any electrical circuit.

I'm only getting 8 volts to fuel pump and I am trying to check ask the grounds on a 1996 yukon where are they all at

What's your battery voltage, Chris? If you're getting only 8 volts to the fuel pump, then don't bother checking the grounds - you have a power supply problem to the fuel pump. You ARE referencing that 8 volts to a GOOD chassis ground, right? Or all the way to the battery's negative post?

The various ground connections could be nearly anywhere - look for any wires screwed to the body or frame - every one is a ground wire.

Have a 1997 Chevy Cavalier LS convertible. Won't start. Battery, alternator and starter all less than 4 months old. Was told might be the ground wire??? If possible or likely, where is it located?

Typically a grounding wire issue manifests itself as an temporary problem that comes and goes. Unless it has been having issues for awhile now and finally stopped starting all together.
So it is possible, it would be the large ground wire coming from the negative battery terminal. It should go straight to the frame or engine. Check to make sure the wire is securely attached to its mounting location and relatively free of corrosion.
If it is going to the frame check to make sure there is some kind of large ground wire that is also connecting the engine to the frame/battery some how and also that its connections on either side are solid.

Where does the ground wire on the starter get grounded

You can bolt the ground wire anywhere to the metal body or frame of the car since the battery is attached to the frame and body all electricity flowing through the body/frame goes to the negative terminal of the battery(ground). Preferably you would bolt it as close as possible to the starter without putting in danger of moving parts or heat though.

Wiring installation on Majestic amplifier total 60watts 2x30 model# ma-60

To install the amp you need a amp wiring kit they range from $15 and up depends on how many watts u have.Once you have the wiring kit start with the ground wire it needs to be no longer then 24 inches long the shorter the better find a good ground in the trunk or where ever you want to install the amp make sure its metal to metal no plastic paint or any other debrie is in the way of the metal.If you can't find a paint free surface all you will need to do to fix this is sand off some of the paint and then ground the amp.The ground wire needs to be connected to the amp before any other wire once you have the ground connected then connect the battary wire make sure you have the right size inline fuse on the battary wire that also depends on the watts of the amp.once you have those 2 wires connected then u will need to pull the stereo out of the dash and hook up the remote wire to the power antanna wire if you have a factory car stereo and don't have a power antanna you can try one of these solutions 1st one Run the remote wire from the battary wire on the amp and use a toggle switch between the remote and battary wire or you can run the remote wire from the amp to the fuse box of the car and hook it up to a fuse that only works when the key is turned on.Once you have all this hooked up its time to hook up the subs/speakers on the amp it should indicate if its bridgable it will show lines from one positive and one negative and at the top of the lines it will say bridge but if not the just connect the speakers positive to positve and negative to negative.If it is a bridgeable amp i would only recommend hooking it up bridged if you are hook up subs if you are using 6x9's on the amp you don't need to bridge the amp.If u have any more ?'s just ask i can help with this i've done this alot.
