block heater cord

[jas2wa]

This morning, 14 degrees F, gf attempts to unplug the block heater from the extension cord, and pulls the entire male end off the block heater cord, amidst a little flash of light/jolt of electricity...

So, now I have a frayed, fried-up looking cord hanging from the front bumper... and no block heater.

Think it is possible to repair the cord, i.e. slice in some new cord with a new male end on it? I really hope I needn't replace the whole thing, surely not-

Advice?

Thanks,

JAS
