The two big terminals are the high current ones. 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.
Solenoid And Coil Wiring After Rebuild Problems Questions
4 terminal solenoid wiring. This is the switch terminal and should get battery voltage from the switch when you are trying to start the engine. Of the small terminals one gets grounded chassis the other goes to the start terminal on the key. 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. Solenoids usually will have three or four terminals. The two larger terminals handle the large currents needed by the starter. Identify each terminal on the solenoid.
The other 2 are for the control circuit. There are two large terminals and one or two small terminals. A 4 terminal solenoid such as pk5230701 requires a separate ground wire. These will be the largest terminals. 4 pin solenoid wiring diagram. The one or two small terminals handle the small signal current from the ignition switch.
Connect one to the battery the other tho the big lug on the starter. 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. The last terminal is usually the r terminal and was used on ignition systems that used a ballast resistor for the coil. One will have a s by it. A wiring diagram is a streamlined conventional pictorial representation of an electrical circuit. 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.
If the solenoid has 4 wires usually one is to the battery positive one is from the solenoid to the starter. Sometimes there are 4 terminals on the solenoid cap and those are. It reveals the elements of the circuit as streamlined shapes and the power and signal links between the gadgets. Terminal b or 30 terminal m or c start terminal s or 50 and ignition terminal r or 15a as shown in fig below. Sat apr 12 2014 800 am. Short of actually seeing it i can give you a verbal.
