Assuming that your car is a negative grounded car, it should not make any difference in the power supply if the metal is galvanised, zinc conducts electric the same. As long as the ground connection is good, it should work fine.

Wire diagram under dash 1996 ford ranger
If the wire is firmly attached wherever it is attached, and properly insulated (i.e. "electrical tape" etc). Then that is not the problem. If the radio is turning _off_ when you hit a bump. (meaning it was "on" and then "bumps" make it go off and on again), then either the radio is loose and needs to be tightened, and/or the ground wire connected _to_ the radio's "metal" is loose; (usually a wire connected to a bolt in the rear of the radio). When I say the radio may be loose and needs to be tightened, I am _also_ saying the radio may be getting it's electrical "ground" just by being bolted onto the car (if the area where the nuts are attaching the radio to the car is made of metal and not just all plastic). // Ok... First, make sure that wire under the dash is a good solid connection and _then_ make sure it is insulated (such as with electrical tape). Then you need to find out if a "ground wire" is going to the back or sides of the metal part of the radio, or if the "ground" is being made where the radio bolts to the car (which would be the case if that area is all metal and not plastic). BTW... That wire that is connected under the dash is connected to "positive". As long as it is a good tight connection, and safely taped or otherwise protected, it is fine and can stay that way. Tighten up the radio's bolts and look to see if there is a wire going to the back metal body of the radio. Make sure it is a good connection. Finally, if the radio is tight, but there is no separate wire going to "ground," and the problem continues... Then the solution is simple. Just add a "ground wire." Run a wire from _any_ area of the dashboard that is _solid_ metal and there is a screw/bolt you can attach the wire to (such as a metal support bracket bolted to the metal dashboard), and then connect that wire to _anywhere_ on the metal of the radio where you can make a solid connection. (There is usually a bolt in the back of the radio that is meant to be used to mount a bracket to make the radio "firm." (so that it _doesn't_ "bounce" around). Anyway, you can attach the wire there if you have a nut that fits the bolt. If not, then simply loosen _any_ screw in the metal area of the radio, and slip the wire under the screw, then tighten the screw with the wire firmly under it. That will give you a "permanent ground," and the bumps won't cause you to "lose ground" anymore when the radio shakes; which it wouldn't do if there was a proper support bracket added to that bolt in the back of the radio. (I've tried to explain this as simply and clear as possible, which is why it is so long, with some "repeating myself". If you can follow this, it _will_ solve your problem). Best of luck... --Gregg

How to install a subwoofer and amplifier
When installing any electrical components always remember to unhook the battery. First thing you want to do is run your ground cable from a volt meter to a body or frame nut or bolt near by in the trunk or hatch area a shorter thicker ground is best then connect the other end of your volt meter to your battery cable that will need to be run through the firewall and connect to the positive battery terminal. Also VERY important make sure you have installed a fuse on the wire in between the amp and the battery. after you have connected the battery cable and ground to your meter it will light up or give you the correct reading for your ground, if not run the ground somewhere else until you have found the right spot. pull out your stereo, for stereos that are made to be compatible with an amp there will be multiple rca jacks in the back of the stereo. For a sub woofer you want to hook the rca cable to the rear or sub labeled rca jacks. Then run your amplifier remote wire to the remote wire protruding from the back of your car stereo. After that you can run the ground and battery cable to the correct slots. Now connect your sub via rca and your done. making it fit correctly is up to you. If you do not have an amp with a subwoofer out then you can take the wires from your sub and bridge the connection to your amp and get enough power, take the positive wire to your sub and hook it up to the positive terminal of channel one on the amp then take the negative wire from your sub and hook it into the negative terminal on channel two and your done.

Water is leaking from the pipe on the top of the tank (Reliance 606 electric) where the hot water comes out and goes into the house. Likely causes?
If tank is rusted out, then that is caused by depleted anode rod, or tank that is not electrically grounded on hot side pipe.
If pipe nipple is rusted out, then that can be caused by improper connection between copper and galvanized pipes, and caused by non-grounded hot water pipes.

If tank is leaking, replace it.
If nipple is leaking, remove with pipe wrench, apply teflon tape or joint compound on threads, and install new nipple. Replace anode rod if possible. Correct copper-galvanized connections. Add ground wire between hot and cold pipes.

90 astro, gas gauge goes to full then drops when shifted into gear to near empty
The grond wire near the transmission mount has failed. The crossmember that goes under the rear transmission mount has the wire harness for the fuel pump and the gas gauge on it. This grond bolt is a steet metal bolt screwed into the top of the cross member near the middle of the vrhical on the passenger side. To repair this problem find this bolt and unscrew it, clean the cross menber and the bolt and the wire. ( they might look clean but they need scraped off) to make sure you fix it I attach another peice of wire under this same bolt and run it up to the battery box. following the negitive battery cable it attaches to the body near ther battery with another bolt . clean this connection also and then attach your new wire to your newly attached wire. It's possible to fix it just cleaning these and other ground connections till you find the one thats not making. The japaniese cars always already have these ground wires on all cicuits and don't have these kinds of problems like this american one does.

I bought a new stereo for my honda hook it up will not work previous stereo did work don't know if the black wire which is the ground has come alose had stereo check its good need to know where the...
The vast majority of cars are Negatively ground. Meaning the negative return for your car runs through the cars frame and metal components. You probaby wont find a ground wire other than the actual negative black wire on the battery, which you will find is attached to the cars metal structure somewhere. Even if there is a ground wire from another compnent within your car to connect to within the car, you can get away without using it. Simply connect the black ground wire from your stereo to somewhere metal, ie slightly under a screw or bolt that goes into the metal subframe or engine firewall under the dash somewhere, join the wire around the screw / bolt and ensure it has good wire to metal contact, the tighten the screw/ bolt up. The subframe / firewall will act as the metal conducter to return power to the negative terminal of your battery. Make take a bit of trial and error to find a good point to join the ground wire but not too difficult to figure out.

Where do i find the ground wire
What are you trying to ground? If electronics, Any bolt attached to the frame of the car can be used as a ground. You can attach a closed loop metal contact to the wire and attach the bolt for a ground. Extra info, bolts that hold down your seats, firewall bolts and seat belt bolts are some common grounds.

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.
