    Default TC33D wont start

    It is a 2004 TC33D with less than 300 hours.
    Here are the systems:

    Used the tractor Monday mowing using rear PTO no problems.
    Tried to start it Tuesday morning and it would not do anything.
    Checked to make sure all the safety switch levers are in place, and all seem to be ok.
    Went back later Tuesday afternoon and it started right up.
    Went back today and now it wont start.
    The starter doesn稚 engage.
    I just hear clicking buzzing sounds under dash.
    The lights dim like a short or dead battery.
    Checked the battery, has 12.5 volts.
    Tried to start with just battery power with a jumper cable at the starter, no luck. Starter did not engage.
    Checked power at starter while trying to start only 8 volts.
    Pulled the panels off sides and looked at the relays.
    The 3 relays were all the same so I switched them around.
    Still wont start, just buzzing at the relays.
    The lights are dim on the 3 dash lights now.
    Headlights are dim when turned on now.
    Sometimes the flashers won稚 even flash.
    Took the key switch out and checked it with meter seemed ok.

    I tought it may be in the key switch?
    Is the key switch a weakness or has that been a problem area?

    I did read some other starting problems on the forum and plan to look at the safety switches again and try some more with the relays tomorrow.

    I did a check on the fuses on the right side but did not remove them.
    Are there any other fuses to check and where?

    Any suggestions?

    I also need to know which fuse is what?
    I have read where people talk about fuse # 2 and fuses # 5.
    Are we talking about the fuses on the right side just to the front of the relays? If so which which is number 2 and number 5?
    I would assume number 1 would be at the top and just count down?

    # 2 fuse is for class III models; yours is a class II. I think the key to your problem is voltage drop. You say it only has 8 volts at the starter. I don't think much will happen with 8 volts. Have battery checked. Clean all terminals. This includes ground wire at battery and at frame mount. Make sure battery cable is clean at solenoid. You do have a main fuse in a holder that is just behind the starter by firewall.

    I actually put another battery on the chassis and hooked it up with no difference.

    I cleaned the battery cables and checked the ground on the frame, all is good.

    The solenoid is on top of the starter, right?
    I checked it, the wire was loose but not bad loose.
    Maybe the loose cable on the solenoid blew a relay or fuse?

    I plan to check all the fuses, relays and safety switches again this morning.
    How do you check a relay anyway? Just switch them around maybe?

    Anything else?

    Can't I take a jumper cable from the pos side of the battery straight to the starter solenoid and make it turnover the engine, no matter what is wrong?

    Not sure if you have had a chance to read this posting I made a while ago:

    http://www.tractorbynet.com/forums/n...lem-fixed.html

    You could have many problems going on, low battery, intermittent bad relay, poor connections for ground and terminal blocks.

    It seems to me our tractor model is overly susceptible to problems being caused by even a slightly weak battery. Unless you have had each battery that you tried load tested I would still be somewhat skeptical. If you had a starter/charger to try it might help eliminate the battery as a problem or use a battery form a vehicle running with jumper cables.

    "Can't I take a jumper cable from the pos side of the battery straight to the starter solenoid and make it turnover the engine, no matter what is wrong?" I believe it should turn over as long as there is nothing wrong with the solenoid or starter.

    I don't think you can do that. The connection to the starter motor is internal since the solenoid switch is on the starter. To check the motor for operation, you need to connect a jumper between the large cable coming from the battery and the small connector. This will provide voltage to the solenoid and make it engergize the starter motor. If this does not work, then you probably have a starter problem. If it does work, then you can continue to look for a relay or switch problem.

    My starter is becoming erratic in its operation also. I'm pretty sure it will require some maintenance before too long. My maintenance manual shows a complete disassembly, so I'm pretty sure the starter can be repaired.

    Update!

    I been at it all morning trying to figure out whats wrong.

    I think it is in the glow plugs. The glow plug light will not come on at all now.

    I hooked up another battery with more voltage, 12.65 volts

    I use jumper wires and by pass the key switch and get the same results.

    Here is what is happening at this time:

    I have 12.6 volts in the system sitting without switch on.
    I turn the switch to the on possition only.
    The voltage to the system drops to 4,5, or 6 volts.
    The glow plug light will not burn at all.
    The oil and battery lights are very dim.
    The voltage starts increasing slowly, the lights get brighter.
    After about 15 seconds, the voltage is up to 12 volts and the lights are normal bright.
    Then after a few seconds it loses the voltage back down again.

    As soon as the voltage gets to 12 volts and I try to start the engine its back dim again

    I can even turn the switch off while the voltage is back up and turn it back on and the lights are still bright for a few seconds before everything starts dimming out again. (except for the glow plug light, it dont burn at all now.

    Any suggestions?
    Is it a glow plug problem, if so where do I start?

    I forgot to mention, I checked all the fuses.
    I also switched all the relays around with no different effect.

    I don't have my manual at work, and my electrical knowledge is limited, but if you believe it's your glow plugs causing the problem couldn't you just pull the glow plug relay out and eliminate them from the system? It almost sounds like to me you have a short to ground or some weak contacts somewhere. Let us know what you find.

    Maybe try wiggling wires and relays when the power drops and see if it comes back up. One of my problems was an intermittent problem with the glow plug relay timer module. I finally noticed it was the cause when I touched/bumped its connector and the light for the glow plugs went out before it should have.

    I will try it. I will also try wiggling some wires around.
