I added the HC Starter Relay Harness to eliminate passing high inrush current to starter solenoid through the ignition switch based on some comments I read in the forum. My own current draw tests appeared to be very low/minimal. However, should the starter solenoid become marginal, the higher draw of the solenoid could damage the ignition switch...imho. I bought the HC Starter relay, base, fuse and harness from Greg Bender at This Old Tractor. It is s nice easy install..the relay base slides
