hard to work with no wipers
« on: September 17, 2012, 06:34:58 pm »
Its like looking through a swimming pool.  Depth perception is all out of wack.

So there's four wires going to the wiper motor.  one is 24v constant one is a ground. Presumably the other two are for the intermittent settings.  It should be grounded through the frame.  Solenoid clicks every time, but the motor doesn't spin.  If I pull the motor off center, it will return to its home position, but that is all.  So I know the motor will run. But the wipers still wont work.  Of all the times for my multimeter to puke, this had to be it.  Guess ill have to get another one for tomorrow.  (Yes I tried new battery in it)

If anyone has suggestions to chase down i would appreciate it.  New motor is 700 bones btw.

I've got the schematics but i have trouble making heads or tails.  Relay k12 is good. Wires are good from plug x46 to x53. After that I lose it in the harness. Fuses are good. This is for my front window wiper motor.

i bought a new wiper motor for my valmet from a place in ok. cant find the name of it. they sold wiper motors and parts for power units used in the oil feilds. they had almost anything you could want. also try hamilton marines web site. ya i know its boat parts. but they stock quite a few wiper motors

My wiper mount from the blade to the motor is a tapered shaft, it was slipping there. Other than that, I am chasing a bad ground myself,my seat direction sensor quit working, I have power and ground there, but I tried 2 new switches and no dice. I ended up taking a 2 pole spare switch I had and wiring it in til I can fix it right. Then my master fuel shut off solenoid quit, ended up being the same type problem. There is power at the plug, but not enough to work the solenoid. That was a fun job, up underneath the machine, there is no way to shut off the fuel other than the solenoid so I got a.really nice fuel bath >:( Eventually I'll get caught up enough that I can chase these electrical gremlins down. BTW, we only use our wipers to clean the dust off of our windshields, I can't remember what rain looks like. It is really dry here right now.

It seems to me that the last time this happened to me with  the wiper motor we had to cut the wire that makes the motor return to home position and just manually stop it where we wanted with the switch .also as was mentioned sometimes it will slip in the tapered shaft and you have to take it off and clean out the grooves so it will get another purchase .

I have had the blades slip on tthe shaft a few times, although in this instance the motor isn't working at all.   Ill look into clipping that wire right away.   Hopefully get it sorted out soon.

Looks a touch dusty. Nice big landing.    Got my problem sorted out.  The circuit had two relays, I only knew of one.  Guess what the problem was?   Thanks for the input folks.

Ponsse Ergo with an H73 head, they handle bigger wood (that's over 16" for us ::)) decent, most of the bigger we get into is big popple, it gets pretty knobby and conky at that size. These heads feed the wood fine, you just have to "float" the knives so they don't stick at the base of a knot. I haven't spent a lot of time in a harvester, I'm still pretty new in the forwarder as far as that goes. 1270d, that landing is an old hayfield. We've been working all summer on blowdown, all small private sales around 300 cords apiece, they all had tight landings so this one was nice. Glad you got your problem fixed ;)

If you was in one of my old hay fields there would be rocks sticking up. All my fields have rocks sticking up now in them now.

There are no rocks to stick up here, it's fine sand down about 10' and then you bit clay with an occasional rock in it.

Did you end up finding an aftermarked encoder or getting one from hakmet or quadco?   Maybe your old one wasn't bad?  Maybe a bad connection that got jostled when you installed the new one?   Do you have a measuring wheel or drive track measure?

i got it from quadco. they sent the wrong one this first time. its a emeta encoder made in sweden. if you have never seen one apart. it has a plastic disc glued to the shaft. the old one was adrift. it drives off the tracks. the dia is acting up also. when first turned on its fine after a while the dia wont change till you push the feed button. i called the keto pro at quadco said he would think on it

I see.  My length encoder uses a set screw to hold the shaft directly to the wheel.  There is a shock isolator in between.  Haven't come across one like yours.  Nice when the service folks say "uhh I've never heard of that problem, ill think about it and get back to you"
