Hey, kids.

I have a 1987 300E that ran perfectly until the engine wiring harness melted on me a few years ago. I posted about this a while back, but I think I now have a better understanding of the situation.

I don't know what caused the short, but I think it likely that there was a tear in the insulation and a bare wire shorted against another, or against the body or hood? Anyway, the whole thing is shot.

It looks like I can get a replacement harness in excellent condition for $500.00. I'm competent to do the work, no problem. It's all one harness in the engine compartment, if I'm not mistaken.

My question is: is there another possibility for the original short, one from elsewhere in the car? I don't want to replace the thing and see it melt on me because the problem was elsewhere to begin with.

Thanks,
Jimmy

Verify the current flow. The only way to know is to test.

I have an 87 300E with the exact same problem, except mine was "self inflicted" when I tried to jump it with the cable crossed.

Could you somehow let me know where you purchased the harness?

I have not seen any priced that low.

Thanks,
Steve
