Bolt head broke on alternator wire, any temporary solutions?

You can make 60 miles on batteries alone (ask me how I know lol)

 

Drill it out if you carry that stuff then slap a bolt through it (mudflap bolts are good to rob sometimes if ling enough

 

If theres enough slack, could put negative wire under the mounting bolt head if you can get to it

 

Vice grips?

 

Might can move it to the bolt here. If it will fit.

 

Whatcha break it fer?

 

Alternator's frame should be grounded through the mounting pads to the engine. In theory you should be able to attach that ground to the engine and be ok. That all depends on if there's corrosion or paint acting as an insulator of course.

 

Every truckers toolbox should have every size of vicegrips .
