What do you need to know about a starter relay?
What is a Starter Relay? A starter relay is a small, electrical device found in the starting circuit of high-current motors. The relay is essentially a remote switch that controls a high-current circuit. In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit.
Which is the ground terminal on a fuse box starter relay?
The “S” terminal (or 85 terminal in some relays) receives a 12-volt signal from the car’s battery. A small current, usually less than 10 amperes, passes down the terminal and through the coil windings and through to ground. In the fender-mounted relays, this is the “I” terminal. In fuse box starter relays, the ground is terminal 86.
Where are the starter relays on an Ural 750?
The Ural 750 (1998-to-2005) uses two 12-volt starter relays, located below the front-seat and above the battery. With the battery and front-seat out of the way, there is free access to these two starter relays (Standard Motor Products RY115), which plug directly into the wiring harness.

Why is my starter not working on my Harley?
That black wire with the red tracer should be sending 12v to the starter relay. Be sure that this wire is not damaged or pinched anywhere in its travel. This will be more common when wires have been routed through the bars, or switch housings/switches have been changed. Don’t forget to use your multimeter inside the switch housings too.
What are the basic principles of a relay?
RELAY OPERATION All relays operate using the same basic principle. Our example will use a commonly used 4 – pin relay. Relays have two circuits: A control circuit (shown in GREEN) and a load circuit (shown in RED). The control circuit has a small control coil while the load circuit has a switch. The coil controls the operation of the switch.
How to keep a relay energised for longer?
Set the timer for say 1 second. Now if the beam is broken for only 1/4 second, the alarm still receives a 1 second signal. But if the beam is broken for 30 seconds, the alarm still receives 30 seconds of signal. Thanks for taking the time to get back to me, I will get back to you all one by one… In principle, yes, this would work.
How does a relay work in a load circuit?
The coil controls the operation of the switch. RELAY ENERGIZED (ON) Current flowing through the control circuit coil (pins 1 and 3) creates a small magnetic field which causes the switch to close, pins 2 and 4. The switch, which is part of the load circuit, is used to control an electrical circuit that may connect to it.
How does the remote starter solenoid relay work?
Current flow when the remote starter solenoid is energized. A secondary function of the starter relay is to provide for an alternate path for current to the ignition coil during cranking. This is done by an internal connection that is energized by the relay core when it completes the circuit between the battery and the starter motor.
