If I had to guess, that's a fusible link that has fused. Or a points ballast resistor wire.

Husband says it looks like circuit breaker; book says 40 amp, pn 4849847, used between 62- 70 in power tops.

That is exactly what it is, used in early 60s Oldsmobiles for most high power accessories. Power top, power windows, power seat, power rear window in a wagon, etc.

Looks like a fire starter.

X2 on that !
It looks like one of the wires was very hot . This was due to very high resistance at the terminal or inside the relay.
My suggestion would be to replace the relay , And re-do all the "funky" connectors .
You can get one here ;

The obvious problem with the OP's circuit breaker is that the wires with the yellow and red crimp fittings are not factory. What do those go to? Has this unit been overloaded? Are these cheezy aftermarket crimp fittings corroded (good bet) thus causing the heating?

KcPaul

thank you everyone and yes its definitely a fire starter Mr My442. and especially thank you to 1014701X. All your wisdom is greatly appreciated.

KcPaul

Wisdom? Nothing of the sort... just tracked it down in a couple of books. Glad to help! Karen

And, just where would I find this circuit breaker located on my 1962 convertible?

The wiring diagram for the full size cars in the 1962 CSM supplement (Fig 13-3) shows the breaker located in the wire between the junction block on the horn relay and the isolation relay that provides power to the power accessories. On my 62 F-85 wagon with power rear window, it is bolted to the driver side inner fender. I can't speak to the location on a 62 full size, but follow that wire and you'll find it.

On my 67 Cutlass Convertible it is located on the firewall low and outboard of the brake master cylinder. The corroded bolt, nut, and burnt wiring suggests that it got very hot at some time in the past. The cloth insulated wire looks like the feed wire but the other one is an aftermarket add-on which means the melted red wire is not fused unless the the factory wire is a fusible link! Maybe a stereo amplifier from back in the '80s? Find the reason for the overheated wire and either remove it or replace the wire after repairing the reason for the short that caused the overheating problem.

Photos of 1962 Olds Full Size cars on the web appear to show the breaker mounted on the firewall, outboard of the master cylinder and power booster.

Found a photo of the same part on my 67. This is what the relay looks like dirty and unmolested, probably since new. I was right that the cloth insulated wire is the feed wire that is connected to the horn relay post. It is not a fusible link so it will provide power until it burns up if shorted to ground. It is located below and outboard of the wiper motor as seen in the upper left of the photo.

joe_padavano

No, that is what a CIRCUIT BREAKER looks like. It is not a "relay".

cjsdad

Oh yeah, senior moment. Oops! Circuit breaker. I don't deal with them any more so it was a slip of thought.
