Those are total junk. You need a constant duty solenoid.

thank you

As midnightman stated, are Continuous Duty and Intermittent Duty solenoids look exactly alike, do NOT interchange. An accessory Relay from a HD Truck parts counter is what you need, or one directly from Case.

don't use this style soliniod . it uses a ground to activate on the tremial screw. You need one that uses the postive to this screw

As stated above, there are two types, continuous duty and intermittent.
This page shows lots of both types.

I circled two of them. They'll indicate continuous or intermittent in their descriptions.

No offense but Thats not true on having to ground the solenoid to activate. It can be activated either way by the small posts. Ground one post activate other with power. Or power one post and activate with ground on other post

 

[DMiller]

Sorry Midnightman but some of these, actually MOST Continuous Duty have a High Amp Pull In winding that opens when the switch is at full closed leaving a Hold In winding to keep it closed, the Ground side is the same for both pull in or Hold and if wire hot to wrong side can keep the pull in winding Hot where will cook.

Doesnt change the fact it will have power all the time while activated. It doesnt matter if its activated by hot or ground. The solenoid is not specific to being activated by hot or ground. It's the same as a relay. Its continuous duty meaning its meant to stay activated. I've used these for a very long time and never burned one up from wiring it wrong. It's my understanding those posts dont matter what's ground or hot or they would be marked. What issue are you having? How are you wiring it?

 

[Midnightmoon]

1 supply 4 load
2 ground 3 signal
2 and 3 can be reversed
I've always run 2 right to solenoid mounting bolt 3 to switch to activate

 

[heymccall]

The one in the first post is for starter (intermittent) applications.
You need "continuous duty".

used the part number and they gave me somthing differant. what they gave me was a single post trigger. that uses the grond to that post to actavate. I think I have other problems. like maybe a altenator putting out AC. I used a plow solinoid and it still heats up with no load,

thanks will order

thanks will order

Its the altenator putting out low voltage causing high curent and burning out switches. Thanks for the help

two large bolts power in and out to starter, when power is supplier from ing. switch to small bolt, it pulls in contacts for the two large bolts, whats the problem Willis?? IF there another small bolts is aux. power supply for things, the gound for solenoid comes from the its mounting to metal, frame/ect
