After you repair the chafed harness, make sure that you install the harness clip that attaches to the starter solenoid so that it won't happen again.

There is also a clip that attaches the small engine harness to the cylinder head to protect the temperature sending unit wire from damage.

Thanks again. I do have the clip on the firewall but not the one for the temp sender. There was a lot of original equipment left off when I had the engine replaced over 30 years ago. I'll order that clip when I put in my next order to Casco. I think the harness got kinked when I had a new starter cable installed and that's what caused the chafing.
