Melted electrical connection...what to do?

Recommended Posts

So I put a headlight wiring kit from LMC Truck on my '96 Cherokee that circumvents the normal wiring and runs the headlights directly off the battery by way of a relay.  The kit runs the lights at 55/100 (low, hi) watts instead of the original 55/60.  One reason I did this was because the light output was terrible, and the other was because for some unknown reason the headlights would shut off after being on hi for a bit.  Never did this on low.  I've had the new wiring kit on for a few years now and it seems to have solved the issue.

The problem I'm having now though is that this new harness is melting at one of the connections...

You can see only one of the wires is overheating while the other seems to be ok.  I'm guessing the hot one is used by the high beams.

What could be causing this?  Could it be related to why the high beams used to shut off before I replaced the wiring harness?  A while back I asked about the shutting off issue on a number of Jeep boards but nobody had heard of this particular problem before.

If you can fix that wire for a quick test that would help.  

Take an amp probe and put it around the wire with and without the high beams on.   See what your reading.  That’s the first thing I would do.  If that wire is coming from a relay then there’s a problem with the wire set up. Maybe an overload on that one wire where there shouldn’t be.  But do that test first and see what the amperage is.

I noticed the butt splice in the photo is also showing signs of burning out. Clear indication of an overload. Is there an inline fuse with this kit? The photo does not show one. Any connection directly to the battery needs an inline fuse. It is dangerous not to have that, in the event of a short, that wire will get red hot and arc out.

Wire gauge appears to be correct (14 gauge) for a 100 watt kit, so you seem to have an overload condition.

I agree with the guys on get an amp clamp on there so you know how many amps your pulling, and put an inline fuse near your battery.

My guess is you have a short in the light bar when on high... On high you it should read about 8.333 Amps, 

Just an option, but I would cut out any traditional but splices, and replace with a soldered connection and shrink tube. I have been testing Solder Seal connectors from amazon and they seem to be working really well. You just need a heat gun to install. They take a little practice but work well.  For marine applications I add an additional section of shrink tube over the solder seal connector to make it extra water tight and a tougher layer of insulation.

I’ve been using the solder seal connectors. I love them. I’ve posted them here before trying to spread  the word on how good they are!

Frank,

I am glad to hear someone else is having good luck with the Solder Seal connectors.

On a side note, I have been surprised at the quality of support Quad Crazy members are providing for the less experienced.  In the short time I have been a member, I have noticed you latch on to a difficult problem and logically walk them through trouble shooting it.  I was originally just looking to pick up the service manual for my quads, and now find myself checking in, and seeing if I have anything meaning full to contribute. I am no mechanic, but work on industrial control systems so I can often contribute on basic electrical issues.

Thanks for the comments I appreciate it but im a small potato here compared to some of the other members.  

I was in need of some help on a problem I was having I came across Quadcrazy and got some really good help here. After that I was always checking in.  

So I think it’s about two years now I’ve been a member and countless bikes later I enjoy paying it forward and helping others as so many of our other fellow members do as well as having other members help me out on my problems.

best site i found in long time and the help rocks just a thanks from us Elmer Fudds trying to do what our parents did to save money but stuff has been made harder on purpose.I have fixed my stuff but have had to go to dealer on my Rhino wiring problem and they said never saw a problem like that before ever so I lucky to have a smarter dealer who guys care.

Keep it great stuff coming but must say I had hundreds of toys like quads bikes skidoos over the years and well guess I have had problems mostly melt downs on older skidoos the bikes and quads are better \I guess 4 stroke is better just costs more.I miss my old ITs yamahas had every size from 125 to 465 490 much more fun then the other one which I cannot think of the two initials I want to say CR but thats Honda.I love Hondas too maybe more more really but all good. Too bad the chinese 2 strokes are over but most were junk really.The cost difference is scary really I bought new pocket bikes for under 100.oo Canadian delivered for that price amazing really.

I put this is wrong place but had to say to other my 2cents worth :Lol Enjoy this site everyone

That’s a great post @scotty2hotty01 I am a big Honda fan.  Yes CR was the initials.  I hand my first cr80 and it was a great bike. 

Ran the heck out of it and quickly went up to a 125 then 250 and swapped over to the Kawasaki where I raced my ass off for a few years.  Then off to ATV’S...... Still like Kawasaki but always loyal to my Honda and always looking to figure out the next brand and project which I’m hoping will be a Suzuki. It’s really the only atv I’ve yet to get my hands on. 

We will see what happens, right now I have this Kawasaki Mojave on the table and have had zero time to play with it.

i was thinking YZ as was a yamaha fan back when |I was young loved the IT as rode in mountains mostly yz were for tracks more as had to keep them in power band the it you could jump over logs what ever hit it away you went.So much fun back in the 80 I ud=se to buy and sell to keep my kids in gas and smaller bikes.My youngest was 18 months old when he got his 1st little 60 had them 70 trikes but some asshole stole them from inside our yard.I still cannot believe that give your kid a hot trike some bad dad for sure I hate thieves.Keep up your great posts bro enjoyed by  many!!!

      i am sure some one has switched from the dinky battery to a larger car car battery, so any advice? ive got enough bits and bobs on my atv that i feel i need to step up, i keep a float charger on it but i left it unplugged for about a week and it was dead and it a fairly new battery from advance auto, im probably gonna add a cb radio in the future and i think the only thin that has a constant draw is the clock in the dash and the memory for the stereo

      Hi all, I was gifted this Bayou but she's been sitting quite some time. It won't crank using the factory start button but when I jumper the starter solenoid it cranks but there is no spark. The key has power coming in on the white wire and when turned on supplies power to the brown wire coming out.

      I guess I should start with testing the pickup? I heard I may be able to jumper the wires coming from the pickup with an LED bulb and it will flash? I noticed in the manual that it should have around 110 ohms resistance so I'll check that as well. One thing I noticed was that the starter circuit relay has power on one of the black wires with the key on- this doesn't seem normal as I'm assuming the black wires are grounds? I think one of them comes from the start switch, travels through the starter circuit relay and then grounds the starter relay?
      Mine is a 1991 so it has the 7 wire CDI (ignitor) and a 2 yellow wire alternator ( as opposed to the later 3 wire type ) with another 2 wires for the source coils (black & red wires ). The pickup wires are blue and black I do believe. Any help appreciated and yes I will test the pickup ASAP.

      I'm trying to understand how the system works and I don't understand what the yellow / red wire from the kill switch does- I assume it gets grounded when the kill switch is "on" and therefore grounds the CDI so it can't activate the ignition coil? I noticed in the diagram that that yellow / red wire looks like it may be grounded by the ignition key switch when in the "off" position?
      I also don't have 12v power at any of the wires going into the CDI- doesn't the CDI need to be powered? I also read on this forum that someone used a GM HEI module in place of the factory CDI just to test it for spark- does anyone have any info on that?

      I hope I'm not missing something simple!
      Here is a link to the diagram for my bike (which was posted by another user): https://www.quadcrazy.com/atvforum/topic/13742-1988-bayou-220-lost-spark/?tab=comments#comment-101193

      Any help appreciated!

      I have a 2004  Kawasaki KLF300. I’m not sure What is the black/yellow, brown, and red wire wrapped together in the wire hornets of a klf300. I got it used and notice some wires not connected. They are located in the front area 

      The reason why I am asking because I’m having issues with it firing up. I cleaned the carb put new spark plugs and gas.

      Hello everyone,
      My Suzuki LT185 didn't come with a battery from the factory (no electric start). I was wondering if I would need to add a battery if I wanted to install some of those light bars/pods or should I just wire it in to the headlight switch? Will the generator be able to put out enough juice to run the light bar? Also, is it normal for the headlight to get dim at idle, then brighter when driving? Never had a quad before with just a generator. 
      Thanks!

      Hey just picked up another scrambler 850 was told the tps was bad.  This atv has been beet to hell.  Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
      my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it.  When I bought it it would pulse and smoke black at idle and die with throttle.
      New tps installed and it won’t run period.  I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps.  Is this normal and if so how should I celebrate it?
