Unfortunately, I cannot put it there as the connection is on a PCB inside the fuse box. To buy a separate fuse box, modified and then replace it is out of question as the fuse box assembly costs 700 dollars for my 2016 Acura MDX.
The load is not a motor. It is a solenoid which provide power to the motor.
So the load is only the coil of the solenoid, like another relay but with strong contacts to support 600 to 700 amperes for the starter motor to turn.
I have a relay for starter solenoid on my car. Due to increasing number of thefts in my area, I want to put a kind of “kill switch”. Something to stop the starter to turn on.
I want to cut the wire from my starter relay to starter solenoid (30 amperes current) and put my own circuit, which I can...
It is OK, Klaus. You maybe missed the Amazon Link. On Amazon, they do not give data sheet. They just sell a product and assume you know how to use it. Distance it is not important for my case because it is under 10 feet.

Thank you, Susan. It is clear like water. I will test to see...
The model I bought to try from Amazon Canada is NOYITO 433MHz Ask Wireless Transmitter and Receiver Module Kit STX882 SRX882 with Copper Spring Antenna but is noting mentioned as baud rate for my TX/RX port.
Thank you very much to both of you for suggestions, but I think I am in the wrong place.
As I said before, I do not have a clue about RF communications, protocols, or hardware.
Maybe my tile should be Pic ==> ? TX ==> ? RX ==>Pic
I will try to search on the web until I will find a forum for...
Hello,
I do not have a clue if this is the best place to ask or not, but I try.
I have a PIC controller and I want to use the UART/I2C/SPI to send a string of 48 bytes BY AIR (wireless) to another PIC.
I do not know RF communication and I tried with some of the shelf cheap transmitters and...
Thank you, Klaus.
I will do it.
According to Espressif document,
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/gpio.html?highlight=gpio%20pull%20up
GPIO35 does not have built in a pull-up resistor,
“Only pins that support both input & output have...
Sorry Klaus, but I did not understand that:
"I recommend to use a BJT controlled by the very power input using a voltage divider at the input.
The BJT´s collector should be connected to an ESP input with enabled Pull-up.
With this you also avoid problems powering an ESP input while power supply...
Klaus, the attached link was just to show how the stop/start circuit works.
Similar principle works on my schematic.
All I wanted is to get a 3.3 volts detection when the outside power it is connected.
I will put after 7805, an 78XX to get that 3.3 volts.
It is more expensive than resistors...
Hello Klaus,
The circuit it works as is part of a bigger project and I have PCB for it and tested.
If you can read Eagle I can send you the schematic.
I am not good on making a table, but I will try to get the original article where I found the latching circuit.
By the way, on my previous...
