This came from an estate of a Volvo marine mechanic he had this put away. I did not find the power cord so I have not tested it. It appears that the on off switch is not original. Please do your own due diligence if you need this the previous owner really was fastidious and took care of his equipment. We pack well and ship quickly with tracking insurance and signature and delivery so it will not get lost local pick up always welcome Riverside, California.
