First major salt dogg problem

The end of last season we were augering the salt out. My employee called me over to show me that the vibrator stopped working. The rest of the unit was working fine.
No power out of the switch for the vibrator motor.
I pulled the controller out and opened the case. To my suprise 4 old type large plug in fuses inside the circuit board. All sodered to the board and one fuse impossible to get to.
I took the controller to a electronic repair shop. He cut the blown fuse out and soldered an inline fues holder to the prongs. Hooked it up and finished unloading the salt.

But we started to hook up the salter unit on the truck. We tested the controller and its acting strange.
The spinner or auger will start when the unit is turned on. But if both are set above zero nothing works. Or if both do start running its very slow ( less than half speed) and if you turn the vibrator on everything stops working.

If you turn the controller off and wait a few minutes and trun it on, all the controls work normally. Auger and spinner both run at normal speeds and you turn the vibrator on everything keeps working.

We checked all the connections. At battery, into the controller and inside at the motor connections. The auger is not bound up or hard to turn.

My guess is the cotroller is shorting out. We replaced the vibrator motor and are thinking of switching out the auger motor.

Give Bob at Karrier a call, they make the Salt Dogg Controllers. They used to be a sponsor here.

Dont know if i would have soldered in a 25-30amp inline on the Printed IP not really real safe looking there so much can go wrong when doing this did they use a heat sink when repairing? a number of things could be going on with that set up, like Todd said Bob is a great guy get ahold of him he has worked with many here to reslove controller issues.

They cut out the fuse and added heat sink to the leads.
He would have had to disassemble part the board to get the fuse out.
This is one of the easier fuses to get at too. One fuse is buried behind the spinner controller and almost impossible to remove.

Thanks for the post about calling Karrier. going to call them tomorrow

I called Bob at Karrier and had a 20 min. conversation. Not sure what to think of his advise. He has major issues with Buyers. He thinks it s a connectin problem and not the controller.

We checked all the connections and even replaced the connection at the auger motor to harness with copper terminals and bolted them together.

We checked the auger shaft thinking it might be binding up. No play in the front bearing and you can turn the auger saft by hand with little effort. We took the auger motor off and put a 12 volt cordless drill on the transmission. The shaft and transmision ran fine and didn't even slow down the drill.

The crazy controller, when you turn it on nothing happens. The controller lights up but no motors operate. If you turn the vibrator switch on the light on the switch does not light up.

If you turn the controller off and then back on still nothing. Not any function in the motors. Turning the speed controls does nothing.

The third time you turn the controller on it works fine. All the motors run at the correct speeds and the vibrator switch lights up and works fine.

Other than replacing the controller I have no clue what to look for next.

You've probably already checked this but FWIW have you checked all your grounds. When ever I have crazy elect. things happening this is the first thing I check and 9 times out of 10 it's a bad ground somewhere.

Well lets see after the following steps....

1. Replaced the vibrator motor.
2. Cleaned all connectors. We always use two tubes of greese on the connectors. All summer they are filled to the top with greese and taped over.
3. Even cut the cheap Buyers auger motor connectors out and soldered copper connectors so we could bolt the wires together.
4. Replaced the auger motor. People thought salt dust got into the motor brushes.
5. Even so far as to replace the controller we had to solder a fuse into end of last season.
Still the unit refused to work. The controller would light but the motors would not turn and the old controller had a jam signal. The new controller would go overload then jam.
I finally gaveup and called a service center. I spoke with the tech and asked if he would do a voltage test and amp test. He said he has never done this tests and he has not replaced as many parts as we have. He thought it might be the bearing and causing the motor to bind. I told him I get the same problem without the motor hooked up. He told me to check the battery.
I thought two batteries and a heavy alt. No way. Then I realized the battery was on a little recharge wire. We checked the battery and had a bad cell. Put a 900 amp crank it the truck and bck to normal. Both controllers worked fine. Go figure a simple battery.

Wow, at least ya found the problem.
Good news is you have plenty of spare parts.

Buyers is now reporting a problem with the controlers on the poly spreaders (1.5 yd. and up). The controlers are not turning off and are sometimes shorting out. Buyers is aware of a bad batch from the factory and are working out sending out new controlers. We have been thru two replacements and they are both bad.

Any idea on what serial numbers had the defective controllers?

Scott Moorman from BPC here.

I'm glad that Rforsha found his problem with the battery. There's not much to these spreaders, so I'm not surprised that his dealer was surprised at all the work. Sometimes the simplest solution...

We have seen some controllers with the Tyco relays that enable the controller sticking (contact welding). This was a batch issue from the relay vendor, and was addressed quite a while ago. All stock has been checked and tested. As TLC mentions, we are working with customers to ensure that everyone is satisfied as quickly as possible.

A controller with one of these relays will function normally, but when you hit the power button to turn it off, the lights will not turn off. These are two LED's, so they will not drain your battery significantly. If you run into this, contact your dealer for a replacement, but keep your existing controller until the replacement is available.

In short, if you have one of these controllers, you will know it. It won't sneak up on you at 3AM (the worst kind of failure).

Thanks,
Scott Moorman
BPC - Director of Engineering
