Car doesn't start. when ignition is turned (new ignition) I hear a relay chatter and my horn sounds intermittely, Battery is new & tested goo


The chatter is due to low voltage. Check all the connections. The battery may have corrosion that lowers the voltage.

A relay in my rooftop model 57915.33 chatters intermitently and trips the shore power breaker.


The reason the lights are not flickering and breaker not tripping when 6 pin harness disconnected that goes to roof unit is because the compressor and fan are disconnected, which would be the major draw that causes it. There is a few ways you can narrow down the cause, or defective relay, but my guess is if it's causing lights to flicker and breaker to trip, it's on the compressor circuit. The fan coming on and off unless capacitor faulty wouldn't draw it down that much, and obviously capacitor is good otherwise it wouldn't operate good when turned on normally. I'd start by inspecting wires to and from thermostat for possible rubbing or touching against one another at a bare spot perhaps. Can't rule out 100% that thermostat isn't defective as well. When thermostat set to cooler temperature, and on, does it turn off and on in normal cycles, to maintain temperature?

2002 Ford Expedition stuck in park, auto windows not working and interiot lights does not turn on.


Check the following..
Fuse #22
Fuse Relay R02
401 Power Window 30a Circuit Breaker.

If any blown, replace (or if relay not functioning)

The park lock relies on power to detect brake pedal, so is locking in Park.

chatter on a relay can mean a few things but since you have just tried to replace it, i wouls check the voltage at the relay,,,,
chatter is caused by i mproper voltage at the relay, coil,

The turn signal relay is chattering. I replaced the relay but the new one is chattering too.


bad earth or short can cause this
also check all globes operating not shorted internally can check with ohms meter if globes dont light up while relay is chattering or remove one globe at time can help to locate area of concern

Luxman LV-111 Home audio amp chatters at power-up.


Hi....

Check on the speaker connections. Make sure theyre firm at both ends. Do you have another set of speakers you can try on it? If so,try that too.
The chatter is the speaker protection relay.

Let me know...Thanks

NO POWER TO MY DEHUMIDIFIER


I took my dehumidifier apart and I found why the unit no longer would start.

First, there is a fuse inside the metal compartment that houses the control circuit board.
However, the fuse was not blown. Instead I found the relay that controls the compressor,
(circuit diagram calls it RY-COMP) was not functioning and was left in the open position.
The relay must switch the compressor on/off based on humidity, full water hopper, and
maybe other factors like temperature.

The RY-COMP is a large black plastic component on the circuit board with two
wires (blue and black) connected at the top. I tested the contacts and they remained
open when starting up the dehumidifier. Doing a small bit of rewiring so that the blue and black wire
were connected and also wired to RY-COMP terminal 3, the dehumidifier came back to life.
However, this is good for proving what broke but without an electronic control to cycle the
unit on and off and to halt when the water hopper is full it's not a valuable alternative and
it risks a burnout of the compressor from constant use.

I think the RY-COMP relay is a solid state relay which could have gone bad from a spike
in voltage when plugging the unit in or cycling on/off.

I certainly don't want to buy another unit where the circuitry is not robust enough to survive
plugging in every couple weeks. I was thinking I could try replacing the relay with a magnet relay which would probably survive spikes much better.
