I took my '71 N600 out of the garage to run the engine for a while
and just as I was taking it off the choke white smoke poured out of the louvers in the hood! Looked just like steam but that's not possible.
I shut off the engine,popped the hood and removed the positive wire off of the battery. The smaller red wire from the charging circuit wasn't red any more. All the insulation had burnt off from the battery terminal down to the connector.
Does anyone know what would cause this and how I could rectify the problem? Yes "rectify" was the pun.
Burnt wire
Re: Burnt wire
That smaller red wire (which is not red anymore) is what supplies power to everything in your car except the starter motor. You appear to have a short. The small red wire would normally go toward the fuse block and if none of the fuses are blown, I would suspect the short is between the battery cable connector and the fuse block. Possibly the insulation rubbed off and the wire shorted to the metal chassis of the car. The largest fuse in the Honda 600 is 20 amps and it took a lot more than 20 amps to fry your insulation. That is where I would start.
Use an ohmmeter to help you find the problem.
good luck,

Re: Burnt wire
I don't recall seeing a red wire in the charging system under the hood on a sedan. There's the main fuse on the plastic block by the volt. reg. where a fat white wire comes off one side to the harness and the other side is white coming from the rectifier. The main fuse is 45 amps.
Originally a fat black wire from the battery goes to the starter, it is aprox. a 4 gauge and to the solenoid is a black wire with yellow stripe.
There's 6 wires on the lead going into the vreg, most are white with a colored stripe and one which is black and is the ground wire. A lot of people don't have their battery properly grounded and it will melt the insulation off the black wire usually all the way back up to the regulator plug.
If the poof of smoke came from under the hood, where is your red wire located?

Re: Burnt wire
I hadn't had time took look at the the car since the wire fry. I went in the garage and looked at the the burnt wire and their were a little fragments of red
insulation still on the wire. I followed the wire down and you could see that this wire had been replaced before. The spade connectors and plastic sheathing were different than the others. From there down you were right, the wire turned into a Y and those wires were white with a red dash on them. One went to the
wire bundle that goes to the interior and the other went to the rectifier. When I pulled the wire to the rectifier the whole rectifier was loose and came up to the bottom of the battery mount. Now I personally know who worked on that last,
me! the bolt was still in the mounting bracket but not attached to anything.
Do you know where the rectifier bracket bolts up to?
Someone said that improper engine grounding can cause this. My battery's
negative cable goes to the front right bolt that holds the cam housing to the
cylinder head. Is this correct? Most cars have an additional ground cable from the engine to the cars' frame but I don't remember seeing one. ( I repainted the engine compartment and installed every thing back about 14 years ago.)
