Lights & Horn Out. . .AGAIN!

[Bob77064]

have you added any after market lights to the circuit? Just increasing fuses wont help...heck you could end up melting down the wiring harness and having to shell out $$$ for a new one.

something else is happening

Agreed, a higher rated fuse will cause something to burn or melt down.

Weather permitting, I'll have the tractor back at the dealer tomorrow and I'll show him your advice. I'm going to watch to see what things look like this time. Since I'm not the only LS owner to experience this problem, surely there is a design flaw somewhere.

Take a Macro (extreme close up) picture of the fuse if you can. and post here.

It has been mentioned earlier, but never replace a blown fuse with a higher amp fuse. I knew a lady once, whose whole house burnt to the ground, because she installed a higher amp fuse for her dryer. Why would a dealer substitute a higher amp fuse than what the factory states? Hopefully the dealer's mechanics are better trained. Best wishes.

Good call on the Fuse.

As with a lot of things, there is more than one way to look at an event like this. You could say "thank God the fuse blew" and protected my tractor from a possible overheated wire and possible fire. You have a problem with the tractor, but the blown fuse is but a symptom most likely not the cause of the problem. A defective lamp socket or a defective lamp can cause a fuse to blow as well as the possible shorted to frame ground wire to I mentioned earlier. It was fortunate the fuse blew to protect the wiring from fire, it is unfortunate what ever your problem is that is plaguing your tractor, that problem is still there.

I mentioned this in the thread TSO had about this...

Under the hood, there is extra wires that are there for cab tractors. They are basically dead ends, and its quite possible the rubber boot covering them has slid back, and they short out against something randomly.

I forget what color the wires are, but if you look back, I am pretty sure I said in that other thread.

I know the plug has both high/low, and turn signal for each side.

I just put in a call to my dealer and he is going to call the LS service representative. We'll see what he has to say. I'll pass on what he says.

OK.. do you believe that is not just a problem with your tractor, but maybe a design flaw? Are others with this model having the same problem?

From what I've read, there are other instances of this problem, how many, I don't know. The dealer says they checked everything on the first go-around--naked wires, proper grounding, switches, etc. This is a very reputable dealer and they don't know where to go next, so a call to LS is the next step.

200 hrs, not a single problem with my 2012 R3039H. Horn and lights work fine.
