The turn/hazard lights on my TC33DA stopped working. I check fuses and bulbs 1st. They are on two different switches so that probably not it. My dealer thinks that its lost ground. I looked at wiring schematicm in the owners manual and it looks like both circuits are on the rear ground lug. But I can't seem to locate the ground location. Anybody know where it is? Also where is the front ground for future reference. Thanks for any help.

Had a number of problems with my TC33d, and found most all relate to the relays so suggest you just go to autoparts store, like O'Reilly's or other and buy some replacement relays and begin swapping themout. The light ones are on the bottom I think but not sure, they are all pretty much the same relay and cheaper at a local parts store. They are located on the right bank just below instrument panel on the right side. Good luck...

moonstruck, I just went through a similar problem. My parking brake light along with the flasher lights in the dash didn't work on my tc33d. Talked to my dealer and he also told me to check the ground at the rear of the tractor. Looking at the tractor from the back the ground is located on the top left in under the fender. Two groups of wires bolted to the main body. My problem turned out to be mice (I think) chewed through the wires behind the dash losing some connections. I spliced the wires back together and everything is working fine. Hope this helps.

check blinker "relay" thing behind the screw off dash panel. $2.00 at any auto parts shop. take old one with you. buy 2 , it will go again...

Thanks to both of you. I still have not resolved the problem so you have given me two good places to check.

Do you have a Volt Ohm Meter. Measure voltage on hot wire at bulb. should bounce aroung as the bulb blinks. If not problem is in supply side (relay, fuse, switch, wiring, connector etc). Work your way back to find exact problem. Check ground at bulb socket to tractor frame l(bare spot or bolt heat), should be very close to "zero" ohms. If not problem is ground. Sometimes with a bad ground it is just easier to run a new wire to a nearby grounded bolt head. Either way you'll know exactly where problem is.
