My hydros were working cool, and all of a sudden, all I could hear is my solenoids clicking. The back goes up fine, but the front barely moves. It is to the point of where I have to hit the switch 30 times to get the front to move 1/2"




WTF is going on??

low voltage to the front, or a bad pumphead, or try to see if something is jammed ;)

Well, would the pump head just go out like that?? I tested the voltage across that bay, and it is at 36 volts, so that is where I am supposed to be.


All I hear is clicking though, I don't even hear the motor spinning :( :angry:

Could be a bad ground. And yes, a pumphead can just go out like that. :angry: It happend to me a few times. Out clownin, and next time I hit a switch, NOTHIN! :angry: :angry: :angry: :( But, check all cables, grounds, and motor. Does your motor stink at all?

If the motor is not spinning and you hear the noids clicking, then it could be your noids are fucked.

Also check the end of the power wires to make sure they are not burnt up inside the cable terminal ends, you could still get the clicking and register 36v even if the ends are burnt up. If you wires are crimped properly, this should not be the problem

Actually, come to think of it, I had the exact prob. once. My spline key cracked, and bound up. :0 :0 check that too. ;)
yep, but check your noids, there seems to be one bad, or maybe them all in that bunch, and check your wiring!!!!!!!!!!!!!!!!!!!! :0

If I check the noid and find out that it is bad, do I just take it into like "Fleet Farm" and get a new one?? Or is this something I would get from Autozone or Napa??

Spline key is the "key" thats connects your motor to your pump. Like a round cylinder piece of steel with teeth on the insde.
I ALWAYS get my noids from fleetfarm! ;) there only like 4 bucks. ;)

They were actually $5.99 a piece :(




I replaced one of them (the one I thought was bad) and it still does nothing, how do I know if one of them is bad???? How do I check?

I just brunt a motor up and took some pics. Hope it helps:

The first pic is of the Prestolite 7070 motor all together:


This is with the endcap and bushing/washer removed exposing the armature/brushes/etc....


With the motor removed....u can now clearly see the 4 brushes. In my case 2 are burnt up from wearing out. they eventually became to short to reach the armature (attached to the motor assembly) and thus arc-welded. The brushes are spring loaded to keep them on the armature with 2 being positve and 2 being negative.


Peeping the other side. This shows the pads that wrap around the motor:


Next we have the motor: From this side u can see the motor inside and the tang key on the end. In this case it is a 16/tang key and each motor varies:


Tang/Spline Key:


This is the motor & spline key removed:


This is the other end of the motor that passes thru the brushes. The end in contact with the brushes is called the armature. In this case it needs to be resurfaced if I was to rebuild the motor. Depending on the motor it might be cheaper to buy a new one. I plan on rebuilding my other motor since it is showing the same signs of wear.


I'm sure others can pipe in if I called somethign wrong or have a better description.. ;)

If it takes you like 30 hits to get it up, your batts are dead or one or all of the batts are shot. Then you said something like the noids click but nutin happens. If thats the case then yes you have a broken noid, heres what you do..... hit the front switch real fast like 40 times then put your hand on the noids and see which one is hot or the hottest, bam theres your broken noid.

All the batteries are brand new, and I have them hooked up in 1 bay going to each pump so that I don't have to charge the front batteries once a week and the rear like once a month....





I did the 40 clicks thing, and all the solenoids stay ice cold.........any other help??
