It definitely sounds like the electrical part of your ignition isn't working properly.When you turn the key, the lck and tumbler turns on the ign. switch in which sends power to the rest of the car.

You will need to get a 12 volt test light and check the trailer connector for a voltage signal to the trailer, it may also have seperate fuses under the hood for the trailer lights if the system is factory installed, federal law requires the 2 systems be isolated, if there are blown fuses find the short in the trailer before replacing fuse(s), with no exceptions the short is always in the trailer. Hint, check the fuses 1st.

Check Main power fuses in engine bay bolted onto front of battery. Some supply the central fuse box (drivers footwell). As the central box is sort of split into 3 main sections 80A 60A and 60A fuses supply the central fuse box Other fuses are 40A or 50A for cooling fan 50A heated windscreen (model dependent) and 50A glow plug (diesel). The central fuse box can be up latched from a metal clip right at the front above the narrow gap directly in front of the fuses themselves. With the central fuse box undone inspect all around wires for shorts. Also check to see if higher amp fuse had been put into lower amp socket and black arcing had occurred. Fuses may seem OK but connector is now fouled. F29 is 15A Interior lights, cigar lighter, Clock and radio. By the way Escorts were notorious for the stalk failing on the left hand stalk (Indicators and Headlights) Spray some good quality contact cleaner with the NEGATIVE BATTERY TERMINAL REMOVED as the substance is flammable and could spark while you carry our several on and off motions for penetration purposes. Got no idea of the year of your 55 van but wires to most Escorts which carry power to the instrument cluster illumination are as follows post 95 are Orange/yellow, Indicators (on stalk) Blue/Yellow and Blue/black, One side of fuel gage sender unit is Black/yellow and other is straight black to ground. Control Lights are Fuse 11 (10Amp) which supply most components in the instrumental panel this wire will be Violet/yellow and finally violet going into the instrument panel. .High Beam and indicators on separate circuit. Final illumination wire maybe Orange/blue. Check all sides for power is any of the wires have no voltage when lights on trace to faulty wire or fuse. Lastly in the fuse box there is a diode (well several) but if my memory serves me right it joins Violet/blue and violet/yellow which leads to the dip relay (standard check for short or open circuit) Cathode is side with silver stripe and black lead of multi tester. if1 or 000 is displayed on digital meter diode is faulty should read a figure eg 075 but that is not an actual reading but example. This is as accurate as I can remember and have some diagrams but remember there's a hell of a lot of wires some with the same colour there maybe 10 violet wires or 5 violet/yellow and not even remotely significant to one another. trace to fuse of control to be sure. Good Luck

SOURCE: push starter button and no start

Evansville! Nice part of the World.
Bud's Harley Shop still there?
O.k. daft thing is the off run switch on the handlebars turned to off?
Failing this will the bike start and run off bumping (Push start).
If it does take a look at the battery (Maybe Dead cell/s) or Starter solenoid wire/fuse.
Solenoid is located near the battery it is the cylindrical item with the main pos+ wire from battery going to it.
Good Luck! could do with a new Bud's Harley 'T' shirt as mines worn out.

My voltage regulator (kmx 125) gets hot when engine starts, there might be something wrong with it...thanks

I think it's supposed to get hot, given its metal and has fins to dispurse heat, so as long as the batteries charging and the lights don't dim it's fine. You could check the charge with a volt meter, while the engines running I don't remember the exact voltage it should be at idle and under load but I think it's 12v idle and upto 13v under load, but check the manual for the exact voltages. If it out of specs it needs replacing.

.i have 1987 kmx 125 it runs fine but im sure it

If the rattle is coming from the barrel / head area then it may well be a worn piston, worn or damaged bore / rings.
The best way to investigate is to remove the exhaust, get under the bike & shine a torch up into the barrel
Both barrel & piston can be inspected by removing the spark plug & slowly actuating the kick-starter

Ride safe
Please mark this as very helpful (if it has been!!)

You changed the back pressure in the exhaust and that is what causing your problem either put the washer back in or have the carb properly jetted

Kawasaki KMX 125 losing power

hi man,
I had a similar problem, so maybe I can help you. it can be connected with air filter. under your seat there should be some kind of cover on the air filter. just remove it. I've noticed this problem when I unrestricted my KMX 125. the hole on the cover on the air filter is too small.
