Was that "the earth cable burns out"- earth cables will burn out due to
1] the connections are loose and
2] the size of cable being used is too small,
increase the size of the earth cable, many manufactures fit a very thin cable to the set which are cheep and nasty, depending on the amperage used multiply by 11/2 times, tell your supplier what the sets maximum amperage on the set and he will give you the correct size. don't get it to long, and always get copper cable not aluminum.this also applies to the welding cable.

I have a 2004 Sea Doo GTI LE That clicks like a bad batt. I have a new batt installed. Ocassionally it will turn over like it should but only for a second. Any suggestions.


There is a bad connection at the battery terminals or cable connections, check the battery posts and cable terminals are shiny clean, check the earth cable is clean and tight at the chassis , check the cable to the starter motor is tight and clean, if all is good there the starter may be at fault.

Is there any buttons on welder to get a earth I have brand new jasic 250 all set up but cant seem to get a earth no spark did I do something wrong


The welding rod lead has to go into the +ve while the current return which looks like a big alligator clip goes into -ve and is clipped to the metal object you wish to weld.
if you are using mig then check the little black switch under the left zero has been switched to mig.
there is a orange power switch thing on the back of the welder that needs to be checked also .

Ba falcon won't start don't won't to buy manual just replace battery immobilizer lights.on turn key nothing


Check battery posts and terminals are shiny clean ,lead terminals and posts often get a black coating on them it acts as a insulation so make sure they are clean, then check the earth is tight where it bolts to the frame. the other cable nuns to the starter solenoid check voltage at terminal .12 volts . with a jumper wire touching the small starter terminal flash the large starter terminal, the solenoid should click in and work the starter. if not it may be at fault. also some cars have a earth coble that connects the frame to the engine ,often fitted from the transmission to the frame.

FIRST OF ALL I WANT TO THANK THE EXPERTS THAT ANSWERED BACK TO MY HONDA PROBLEM,BUT I STILL HAVENT HAD THE CHANCE TO FIX MY VEHICLE.OK THIS IS HOW MY PROBLEM STARTED.SOMETHING WAS DRAINING MY BATTERY SO I...


The fact that you've had no ignition or dashboard lights when you've turned the ignition key is mainly pointing to :
  • A failed battery.
  • A discharging battery via a failed alternator (the rectifier can burn out, causing the battery to rapidly discharge).
  • A 'bad earth'
Start with the easiest thing first. You say that your car started with a boost - a jump start - which suggests that your non-starting problem may be due to the battery or the 'earth'. When you connect another battery to your own via cables, your car is using the other car as an 'earth'.

A quick check - if you have battery jump cables - Connect a jump cable to your battery negative terminal - the earth terminal (black cable) and connect the other end to any suitable metal point on the engine/bodywork of your car, and try and start the engine. If it starts, it's now telling you that the problem is that of a bad earth.

A 'bad earth' can be caused by corroded cables- check both battery cables for a greenish/blue corrosion and/or broken strands in the wire.

Bear in mind that if you disconnect your battery you may lose your radio code. But .. loosen and turn each battery terminal to clean it and fully retighten. Then check the battery earth lead - the black cable - where it attaches to the engine/bodywork. Loosen and clean the cable and attaching bolt. If a car has a 'bad earth' it can cause sluggish/non starting problems.

If you're quite happy that the battery terminals, cables and earthing point on the engine/bodywork are clean, tight and ok ... suspect the battery.

Don't rush off and buy a new battery. Get somebody to jump start your car and then drive to a workshop and ask them to check it out whilst the battery is in situ - they can also check the alternator output at the same time.

Xterra won't start when the battery has juice free of corrosion and starter is freshly installed


Check the cleanliness and tightness of the battery terminals. Loosen, twist and retighten them. Also check the cleanliness and tightness of the black earth cable where it attaches to the engine block/bodywork. A bad earth can cause the symptoms you describe.

A quick check you can do is to connect a jump cable to the battery negative terminal - the earth - and connect the other end of the cable to somewhere suitable on the engine/bodywork.

If the car starts no problem with the jumper cable - it's pointing towards a bad earth/connection somewhere on the battery earth

Replaced battery, starter good, will not crank


Do the basics. Check that the battery terminal connections are clean and free of corrosion and that they are on tight. Check that the main relay is triggering when the ignition switch is engaged. follow the main cable to the starter motor and ensure that all connections are clean and tight. Check that the cable to the starter solenoid (sitting on the back of the starter motor body) has voltage when ignition is switched on. Check the condition of the earth strap between the engine and chassis and again ensure connections are free of corrosion and tight.

Hi, I have a murex tradesmig 160, when welding its like it loses its earth, but earth ok, some times get a good run, and then wont work. feeds wire but no power.


Look inside the unit (make sure the set is unpluged from the wall socket) and check the bolt that secures the cable to the socket, remove the bolt and clean the earth lead and the socket, check that the cable is ok and tight when refastend.
