One will have a s by it. Identify each terminal on the solenoid.

4 terminal solenoid wiring. Collection of 4 pole starter solenoid wiring diagram. Sometimes there are 4 terminals on the solenoid cap and those are. This is the switch terminal and should get battery voltage from the switch when you are trying to start the engine. Sat apr 12 2014 800 am. Solenoids usually will have three or four terminals. A 4 terminal starter solenoid like the pollak pk5230701 needs to be wired so that the 12v power inout is connected to the two larger terminals while the two smaller terminals are connected to ground and an ignition source.
It reveals the elements of the circuit as streamlined shapes and the power and signal links between the gadgets. There are 3 terminals on the solenoid insulating cover also called starter solenoid cap those are terminal b or 30 terminal m or c and start terminal s or 50. The other 2 are for the control circuit. The one or two small terminals handle the small signal current from the ignition switch. These will be the largest terminals. There are two large terminals and one or two small terminals.
If the solenoid has 4 wires usually one is to the battery positive one is from the solenoid to the starter. Connect one to the battery the other tho the big lug on the starter. A wiring diagram is a streamlined conventional pictorial representation of an electrical circuit. Terminal b or 30 terminal m or c start terminal s or 50 and ignition terminal r or 15a as shown in fig below. A 3 terminal solenoid grounds through the hardware so if you didnt run a wire for ground to the 4 terminal solenoid then that is your issue. By rmaxey fri may 04 2012 810 am.
4 pin solenoid wiring diagram. The two larger terminals handle the large currents needed by the starter. A solenoid that has 3 terminals total such as tr118665 grounds through the mounting hardware so it must be attached to a clean and corrosion free bare metal surface if not otherwise internally grounded. A 4 terminal solenoid such as pk5230701 requires a separate ground wire. Short of actually seeing it i can give you a verbal. The two big terminals are the high current ones.
The last terminal is usually the r terminal and was used on ignition systems that used a ballast resistor for the coil. Of the small terminals one gets grounded chassis the other goes to the start terminal on the key.
