Default Volvo 740 spontaneous oil fire, battery to starter cable destroyed.

Hi,

So disaster happened... yesterday my 90' 740 caught fire... it hadnt been started for over 24hours...

the pictures will show what happened...
something to do with the battery cable to the starter motor i believe, which got hot enough to start an oil fire. not sure where the oil came leaking out of yet...

any advice would be much appriciated... whether its salvageable, and where the oil spillage may have originated from

also there is a cable that is still coming up and frayed, possibly another ground.

im hoping that the oil fire didnt fry anything under there....

maybe the starter motor will be toast.

Well, great thing about Volvo, it's usually less bad than it seems! Change the wire, go from there; how much damage is there besides the burned wire? The starter burned?
Hard to say from here where the oil came from...

Check the power steering to see if one of the hoses melted. Also check the front of the engine for maybe a crank seal or a cam seal. I assume you did not have the oil leak before the fire??? Also replace the bad wires and see if the starter works. Check the battery to make sure it is charged.

I could tell in 2 seconds what happened!

You didn't take care of an oil leak, rotted your primary cable, it shorted to ground, got all ****ing hot and started a fire. The extra oil didn't make the fire burn any slower, needless to say.

thanks everyone that had suggestions!

I got a new power cable to the starter from junkyard $4.50 and did that and it started up.

i cleaned it up down there and found the leak of fluid in the power steering hose. just a small hole, but was big enough.

Im fairly sure, as suggested... that the cause was the power cable and ground cable section where they come apart was worn down from 190k miles. Eventually enough to ark and maybe burn small hole in the steering fluid line.


BUT MY VOLVO LIVES TO DRIVE ANOTHER MILE!
