i have no electricity in my ex the battery is good though any ideas

 

Blown Fuse maybe.... On my 400 My negative cable broke off the chassis. You might look there

 

On the 300ex there is a 15a fuse under the seat/fender about six inches in front of the battery in a small black plastic holder.

 

my fuse is good and the cables r connected i have no idea but i really dont want to take it to a dealer

 

You sure you checked the black cable and ran it back to where it is gronded to the chassis??

 

i am positive because that broke before on both ends and fixed it good

 

Have you measured with a meter the voltage while you attemp to start it? You may have a good battery unit you place a load on it. Is the neatural light illuminating when you turn the key on? Next suggestion is to follow the main positive power cable and look for a loose connection and measure voltage at each postive point.

 

get A 250X!!!!!!!!

 

You say you have no electric... specify the problem. Are there lights working,if so will the starter engage? Electric problems are just a matter of process of elimination.Usually start with connections at the battery. Then go to the fuses and check them. A good point was made about the battery maybe being good enough for lights but not stong enough to crank the starter.In which case you will need a new battery. Can you try another battery in the machine that you know is good? Good luck ...

 

From your first description I will assume you have installed a new battery but have no power anywhere on the machine, not even the lights. It might have a broken wire or bad connector somewhere. The best way is to trace it with a voltmeter starting at both battery terminals. Then hold one probe on the positive terminal of the battery and hold the other probe on an unpainted surface or bolt on the frame to establish that the negative side of the battery is connected to vehicle ground.

If ground is connected, clamp one side of the meter to ground and check at the fuse holder with the other side of the meter. If you got it there go to the other side of the fuse holder with the fuse in. You might need a sharp point to pierce the insulation or find the other end of the wire, probably at the switch. Just follow the path till you don’t find the voltage then you know where the open circuit is. A schematic would be useful

If you don’t have a meter you can use a light bulb. Something like a brake light. You probably would need a bulb socket also to connect the wires to it. If you don’t have those things handy you could get them from some old machine, auto wreckers or something. Use your good battery to test it first...
