Not necessarily related to much, but just figured id ask. I have a salt spreader that I will need wired up before winter. It has two wires coming off of the motor. My question is there an easy way to wire this up? Ex: Run a wire from battery to switch so i can turn the spreader on and off, then from the switch to the spreader??? Anyone know what the two wires would be on the spreader motor? I imagine a positive and a negative.

Any input would be much appreciated!!!
 
should be a positive and negative on the motor, assuming its DC, which i wouldnt see why itd be AC...

if you hook them up backwards, the motor will spin in the opposite direction, so test it first before you finalize the wiring...
 
It probably pulls a reasonable amount of current, so you might not want all that juice going directly through your switch. I've melted a few that way - good fire hazard.
Instead, get a standard relay, and use that... 2 wires come from the switch to the relay, when the switch is on it connects these two, so the relay connects the battery to the motor.
 
thanks for the input so far. ill look into a relay and try to wire something up. what guage wire would you recommend?
 
is the battery and everything going to be self contained on the spreader, or is it one that will be wired to a tractor/vehicle? basically how much wiring are you looking to need? Id say 14-16ga but you may need to go 8-12 depending on current draw and wire length...
 
and you'll need something rated continuous duty for that load.. a 40 amp Bosch automotive relay isn't gonna cut it.

Check places like AW direct or others specializing in service vehicles for one.
 
mistake! its got 3 wires coming off of it! one was cut thats why i didnt notice. i was going to run it off the truck battery with 8-10 guage wire. what would this third wire hook up on the motor be for??
 
what size and rating motor is it...need to know that to determine the load, and then determine the wire size required for that load. Do you know the manufacturer and model? Maybe can find wiring info/diagram online?

My thoughts on the 3rd wire...motor was originally intended for another application and is 2 speed...one ground, one positive for low speed, one positive for high speed. Like a fan motor. One wire (the speed you don't need) clipped at the spreader manufacturer. Cheap way to get the motor/speed they needed, maybe.
 
good thought. i know NOTHING about this thing! it has no information on it anywhere! not even the motor... really weird!
its got about 2 feet of 8 guage wire coming off the motor. i think im going to just touch the wire leads to a battery to see if the motor even spins.
if not it might not even be worth my time or money to fix it. i mean replacement motors are like $250.
 
I think the same about the three wires, a ground and two speeds. As far as size, there's no success like excess. I have a butt load of 6 ga I will give ya if you wanna come get it.
DC motors are usually too expensive to have fixed if they aren't burnt slap up.
