1710 Ford cold weather start

[Hobo Dewey]

12 volts into switch. 2 to 8 volts out depending on what day I check it. Zero amps out unless my amp meter is defective. I did find a replacement switch for $40 plus shipping but opted for the OEM from the New Holland dealer, $85 plus tax. Didn't want the hassle of dealing with a company by mail if the switch didn't fit. Switch is to arrive at the dealer tomorrow morning.

New OEM switch installed. Problem solved. Hope this switch lasts as long as the original, 27 years this past summer! If anyone is interested, here is the site where I found a non-OEM switch for $42. Ford Tractors Parts: Electrical Parts || Weaver's Compact Tractor Parts & Compact Tractor Salvage
I decided to use the OEM switch even though it was much more expensive mostly because I could actually compare it to my old one before making the purchase. Thanks to everyone for your comments.
