Works for TC35D glow plug relay
5 Stars
Works for TC35D glow plug relay
I had a heck of a time getting the right part for my 2001 New Holland TC35D when my glow plug circuit was going faulty (GP light would come on during operation then later wouldn't come on at all when starting).I replaced the glow plug timer (like $90) and no change (very disappointed, I should have tested with voltmeter while applying 12 volts like I did later). Then I ordered the wrong relay. I then ordered the above relays and installed and it works just great, very satisfying.To fix your faulty glow plug circuit: take off the side panel (4 bolts). Look at the relay set. On the lower set of four the left one is the glow plug timer - test with voltmeter and 12 volts power to see if continuity occurs between two of the pins for five seconds after power is applied then turns off. Then test the relay, see if 12volts will create continuity between two of the pins. In my case the relay was faulty and was cheap fix, easy if I had gone that route first. Best of luck and enjoy that sweet tractor.
