My starter solenoid has no markings as to which side the positive cable from the battery should attach or the cable that goes to the starter. This is a three pole starter. Does this mean it does not matter how it is connected? I could not find the answer by searching so hopefully someone can point me in the right direction. Thad

The positive pole must be connected to the solenoid coil, or nothing happens when the other end of the coil is grounded.

True on a 4 wire solenoid, the gentleman has a 3 wire, therefore the solenoid coil is internally grounded to the mount. Lee😉 |

Both the three & the four terminal solenoid are internally grounded. The fourth terminal is used to bypass the coil's external resister, when the starter is engaged. This give the engine hotter spark for starting only. The four terminal solenoid should be installed with the solenoid, or relay terminal, closest to the heavy post that is connected to the battery. AIUI, This is so that shorting these two terminals out with a screwdriver to start the rig is easier. It will work just fine with the coil resister bypass terminal in that position, as long as the wires are connected to the correct terminals, but it is incorrect. In the past I have installed a four terminal solenoid incorrectly. It worked fine, but it was tougher to short out the solenoid. I do not believe that Willys ever used a four terminal solenoid as they did not use external resisters with their coils. I could be wrong about that though. Note: A four terminal solenoid can be used to replace a three wire one, just leave the fourth terminal wireless. IHTH, Cpt Logger.

Sir you are 100% correct on a FORD solenoid, a typical non FORD or industrial 4 wire solenoid the two small terminals to engage the solenoid, one would be a ground and one would be a positive. Lee Edited by Lee MN - 27 Jan. 2023 at 6:30pm |

All the ones I have seen used on vehicles must be the Ford type. Even the forklifts & large cranes I worked on had the Ford type. IIRC, Caterpillar also used the Ford type. I have only seen the Ford type used on aircraft as well. However, my experience does not mean that the other type was never used on vehicles. Thus, I sit corrected. I have seen the type you are referring to used in sawmill & factory operations. I highly doubt that the OP has one of those. Yet, I could be wrong, it has happened in the past.

Well Sir then we can agree to disagree, I spent 35 years in a service truck working on every type of construction equipment used in our market, rarely ever seen a FORD solenoid used in anything other than a FORD. Lee😉 |

Many starter solenoids need voltage applied to the small terminal to activate the solenoid. Ford 6-volt solenoids required the small terminal to be grounded to activate it. The Ford starter button had only one wire connection. The other side of the switch was connected to ground through the retaining clips to the dash panel.
