Why would my jeep keep going through starter solenoids? I replaced it about 3 months ago, and it went out sunday. The jeep just gets trail ridden, hardly ever mud, and never deep enough water to reach the solenoid. I need yalls help please??? thanks
I had the same thing with a cheap Quadratech solenoid. It kept sticking on and finally killed my starter gear. Went to Advance and got a more expensive Borg Warner ($18) and haven't had an issue since:
How do i know if it's the starter gear? Since i made this post i went to Advanced Auto and bought a starter solenoid, it didnt fix the problem. When i try to turn over the ignition, it sounds like a someone welding a bead??? Then about every other turn of the ignition, there is no sound. When there is sound my battey volts are @ 13, with no sound there are no volts. I hope this can help diagnose the problem. thanks
Double check all your grounding points and the + feed wires for faults. Shorting to ground will cause the arcing sound you described. Especially crimped connectors for loose connections/ corrosion.
I was seeing this for a while too. Mine turned out to be a bad ground wire from the battery to the block. Once I replaced the wire, I havent burnt one up since. Over a year now with heavy trail riding, both mud & moisture.
I am hoping it is a short in a grounding wire. Last night i was rewiring some, and noticed the ground wire from battery to the block, like said above. So i will change the wire today and maybe it'll fix the problem.
What kind of wire did you all use for the ground? The wire i am talking about goes from the engine block and mounts under the motor mount?? It is only about a 10" piece of wire? I was going to get battery cable wire, but Advanced Auto didnt have any short enough.
OK, I suggest you try and first measure voltage accross the battery terminals with a voltmeter as you try to start the engine, if the reading is around 12 volts then the battery is OK. If the battery terminal voltage drops way below 12 volts while cranking , you have a bad battery.
Next check the voltage with a voltmeter from the battery side of the solenoid to engine ground while trying to start the engine. The voltage here can be anywhere from 12 to 10 volts depending on the size and length of the battery cables to the solenoid and engine ground from the battery. If the voltage goes way low here chack the battery cables to the solenoid and to the engine ground. The starter gets the negative battery connection directly fron the engine ground, so a bad negative battery to engine ground cable/connection can cause a problem like yours.
If all is well next measure the voltage from the starter side of the solenoid to engine ground. You should see anywhere from 12 to 10 volts when trying to start the engine.
The starter is really around an 8 volt motor, you will see voltage drop accross the battery and ground connection while trying to start your engine becaue the starter draws lots of current, so if you are getting at least 8 volts to the starter terminal while cranking , it should work just fine.
If your starter is bad, it can draw excessive current and cause large voltage drops accross the battery cables. Sometimes a bad starter can cause these symtoms.
Your dash voltmeter gauge really only starts reading at around 10 volts, so it is not a good indicator of starter voltage while cranking.
