Sentences with phrase «relay coil»

Consider aternating the two flasher lamps by controlling a relay coil with the flasher and using the NO, NC contacts to alternate the load, current will be halved and will also be more constat as one switches of as the other turns on with only the one inrush current causing the voltage dip.

It gets defeated by the 12v coming out of the relay coil.

The reason why you were probably told to use a Flyback Diode on pins 85 and 86 is because that is the proper way of protecting the relay coil circuit of a run of the mill relay.

Since you can ground the relay coil and the A / C works you can rule out a couple of things like the compressor clutch fuse, relay and wiring to the compressor clutch.

Not exact matches

I have changed the battery, fuel pump, fuel relay (the one that mounts near the hood latch), spark plugs, ignition coil, distributor cap and rotor button, and the electronic portion of the ignition switch.

There are new HT leads, ignition coil pack, fuel pump and relay.

the ignition coil pin 1 and other sensors pull power from the efi relay.

if you're only getting 8v at the relay than the coil either isn't closing or it is and something is causing draw on the system.

When the coil inside the relay burns, or the armature gets contaminated by something they can sometimes act up and look fine but will make that odd whining sound.

For most relays (i.e. «dumb relays»), the internal construction consists of a solenoid coil that actuates an armature which connects and disconnects a circuit (based on the type of relay).

Failing that, the coil current on the relay for the new HiD lights might be low enough that you could get away with putting a variable resistor between the 7/12 V wire and ground and then connecting the HID relay to the wiper (the third, variable connection).

Yes the voltage is relayed from the contact breaker on the front of the crankshaft, its the spring that causes the real voltage pulses inside the coil box.

Attached to the end of the coil is an interrupter or trembler, a magnetically operated switch or relay, which repeatedly breaks the primary current to create flux (changes) in the transformer needed to produce high voltage.

I assume some heating from the coil could be normal, but corroded contacts would also produce heating and one explanation for the codes could be the relay dropping out.

The coil resistance is about 145Ω when the relay is cold and about 165Ω after the coil has been energized for 30 minutes.

After about 30 minutes with the coil energized, but no current on the switched contacts, with an ambient temperature of 18 ° C (measure with a K - type thermocouple on a DMM), I read a temperature of 25 ° C when the relay is sitting on the thermocouple which is sitting on my desk.

Check if a freewheeling diode is installed (if possible) in parallel to relay's coil.

Other possibilities: A restricted fuel filter, a problematic fuel - pump relay, and it may also be worthwhile to remove the coil wire and inspect for corrosion that could cause a high resistance.

HVAC preventative maintenance, removal and installation of coils (both condenser and evaporator), condenser fan motors, contactors, relays, and fuses.
