Flasher / Turn signals Intermittent on CK-20

[malk315]

Hey Guys-

Was doing a hay-ride for the halloween party today (will try to get some pictures posted). Pulled the hazard lights and nothing.

Headlights work fine, high beam / low beam. Tail lights are fine, brake lights are fine.

After 1st hayride they started working again -- checked that turn signals worked and hazards -- all fine, then suddenly stopped again.

Before putting the machine away, I checked the fuses and there's a turn signal 15A fuse that looks fine (didn't meter it -- I have a meter and will try more later when I have more time).

Wiggled wires going to flashers and tapped on dash near flasher pull-out switch, tried jiggling turn signal switch. Nothing working.

Well get out the meter next time to start checking continuity and measure voltage on fuse and other areas, but was hoping you guys could give me some clues on other areas to meter (i.e. where the wires are routed and terminated with connections so I can trace power to no power and maybe isolate it to a switch or connector or flasher unit somewhere).

Must be a poor connection somewhere but couldn't find anything easy to get at except some round "bullet" or "butt" connectors under each fender which I pushed in to make sure they had contact. Still nothing.

Will get some brake / electric motor cleaner (contact cleaner) but would like all points of contact you guys might know about (anything under the dash?) how hard is it to get under the dash? I had my dash take a bath in hydraulic oil when I first got the tractor last year from the clogged HST vent.

Part # of service manual that will have all wiring diagrams and such I can have my dealer order one for me???

Seems silly to bring this to the dealer when it's got to be something simple.

Thanks for any info.

i had one of the connectors come loose under the left fender. i think it was only for the one side though. worth checking out though..

That's good to know -- I must have lost ground or something earlier than the individual fender connectors, both flashers no workie!

Called dealer and I learned I can pull off the lower cover by removing 6 screws (no need to remove steering wheel and upper instrument area which is good -- a lot of wires up there) and there's like 6 relays under the lower cover where one is the flasher unit. Hopefully I can use a meter to check flasher unit for input power and check around the flasher pull switch to trace back to where the power disappears. I'll also check for power at the fuse block under the hood. Won't get to it til at least the weekend and will hopefully locate and fix the problem.

Fuse block is setup nicer than I thought -- 3 spare fuses of each type w/ extra slots for additional stuff, fuse puller included. Saw the 10 amp fuse for the "customer" circuit which is the butt connectors hanging by the top of the gas tank ready for use, plus the expansion for the lights circuit (15 amp) that has connectors available off a plug on the left fender below the gas tank area. I'd like to add a work light or two facing backwards and it might be worth combining figuring out the flashers with adding lights... We'll see how ambitious I'm feeling this weekend.

I'll provide a full report for others for reference.

This may sound stupid and ignore this if you have done it allready but have you checked the actual bulbs inside the flashers?

They might just be loose or getting a dodgy conenction.

Just thought it would be worth checking this before you dive into the deep end

Some reported bulb socket corrosion although from what you describe i'd be leaning toward a turn signal flasher- that could be common to flashers and turn sig's...maybe tap on it with a screwdrver handle when things are inoperative and see if it springs to life.

We had a similar problem on a 2007 DK45S. The four-way flasher worked intermittently, and when you turned on the headlights, a fuse blew. The problem was two loose wires on the headlight / signal switch. We re-soldered the connections, and now the lights and flashers function normally.

That's great to know -- thanks for the picture.

That looks like the same turn signal / headlight switch as the CK-20.
Now I have a preview of what to expect most likely under my dash.

I will check the bulbs before going in deep, but I'm expecting I'll need to take the panel off under the dash and go from there.

Does anyone know the proper way to remove the black pull-out switch properly that activates the hazards? It unscrews w/ a nut from the panel it's mounted on, but I'm wondering if you just pull extra hard on the knob or unscrew the knob to get the knob off so the unit can be removed from the panel?

The same question would apply to the headlight / turn signal switch -- proper way to remove it w/o ruining it?

Here's a picture to refresh anyone's memory of the layout -- unfortunately the headlight switch is obstructed by the steering wheel.

Does anyone have a part number for a shop manual or manuals so I can get some form of wiring diagrams or any other documentation that goes beyond the owner's manual? My dealer unfortunately didn't give me any answers when I called and mentioned the problem to them. They offered to fax a diagram of some sort -- but I'd rather go to the source if I can -- the shop/service manual for a CK-20. I realize it may cost some decent $$$ to get one, but it's a one time cost for a boatload of info to help w/ future things I may want to do myself.

Any dealers on here could you help by specifying part #'s of books that will have wiring diagrams and other assembly blow-out diagrams for the whole tractor?

Thanks.

Forgot link to picture of CK-20 operator area.
Here we go:

I think the hazard knob unscrews
I think the headlight switch knob would have to pull off and likely theres a nut holding the body to the dash.

If it were a BMW there'd be a special $267.00 tool necessary

Took lower panel off, unplugged "signal flasher relay" that's near clutch pedal.

3 wires - blue, black, and green
One is "Drive" the other is "ground" and I can't remember the 3rd label on the connector.

Blue wire has +12 volts when a meter is put across blue wire and either of the other two or to a misc metal part of tractor.

Tried jiggling hazard switch, reaching under w/o taking dash off, nothing.

can't really get under there w/ dash on and I'm too chicken to take the dash off for fear of rendering tractor unable to move (key switch will get hosed etc. most likely). Plus I have no documentation and apparently there isn't any -- still no one will give me a clear answer (my dealer or anyone on here) if there's a "service manual" I can buy that has ANYTHING beyond what my owners manual. Come on guys -- is there a part # of CK-20 manuals used in a shop??? A simple yes here's the number or no will suffice.

Any other ideas? How to bypass the flasher to see if hazard bulbs light up and stay on w/o flashing? I'm too afraid of wrecking something to just start shorting the blue wire to the others.

I'll probably take it to the dealer -- now my parking brake lever and cruise control lever (red and yellow handles) are all scratched up and dinged (slits in them) because you can't get them through the lower panel slots w/o scraping. This is exactly what ticks me off and the reason I don't take the dash off ... it'll never be like it was when new.

I'm not happy.
