yes I have a volt meter, what should I check ?
I disconnected the positive cable at the generator
Double check the generator cable you disconnected didnt lean over and rest itself on metal?

Turn your volt meter to the setting that makes a beep when you touch both probes together. Then touch one probe to the red cable that smokes, and the other probe to nice clean metal on the frame.

That should tell you if you need to start searching for the relay youre talking about. I dont understand that part but will keep up with the thread.

In my opinion, it's not all that essential to check to see if the melty wire is shorted to ground with a meter; obviously it is, or nearly so, since it's clearly been carrying an abnormal current for the generator just sitting there. (One would expect essentially zero current, maybe a couple milliamps at most, when the generator is shut off, and perhaps a couple amps when it's running, and somewhere around maybe 100A when its cranking.)

The solution is to trace along the wire and find where it's shorting to ground. I'd be pretty confident it's somewhere along the wire between the battery and the generator, rather than a problem in the generator, provided there's no obvious evidence of bad things in the generator itself--things like burn marks, or melted insulation on wires, or loose wires on the starter or starter solenoid, etc.

I'm not saying that checking things with a meter is never a useful diagnostic technique, just that in this case the evidence is abundantly enough clear that it's unnecessary. Similarly, if you find a big puddle of oil under your engine, it's probably not too necessary to check the level on the dipstick; you can be pretty sure it'll be low without checking.

The reason to check both cable ends with a meter (battery end and generator end) is to see if the readings are the same, then you will know it is the cable going to the generator.
Then run another cable from battery to generator.

OK everyone thanks to yours comment I'm up and running.

I believe the problem has been solved. The snow which accumulated in the engine compartment was building up while driving and when I stopped it melted and fell down on the different electrical connections and caused a temporary short. Thankfully the cable connections to the positive battery posts were the weakest in the system and caused the heat build up and melted the connections. I would have thought a fuse somewhere in the system would have blown but the post acted as the fuse and melted instead.

Luckily my 6v battery had a post which was not affected (the original connections were held in place by a bolt) I installed a new terminal on it and redid all my connections. Everything appears to be back to normal.

Thank you all for your inputs ! [emoticon]

[emoticon] Hi, melted connections are not caused by a short; They are caused by a poor connection. A heavy load with a poor connection creates heat.


This is 100% correct

Really, we're all just jealous of someone that can camp for 13 years and only have a handful of problems/questions [emoticon]
