Nedavno Dodgy pise:
| A wire wound electro magnetic component like a solenoid when switched
| off will produce a power spike as it's magnetic field collapses. This
| spike can hurt delicate electronics, so it's best to just short it out
| with a diode.
| That's my guess to it's function anyway.
| It could also be a zener diode, to prevent too high a voltage being
| presented across the solenoid... Only the number from it will tell.
It broke to peaces when I tried to remove it, so I can not read numbers
If I can find another hot water shut off valve that I can read diode
numbers from, would it be a mistake to put it further up at connector
(not as originally at the end of solenoid wires)? I replaced diode
while valve was out of the car, but now it is hard to reach.
BTW I put a diode that is about the same size (4mm long and 1.5mm in
diameter). How do I check if it is not burned (without removing it)? I
thought that resistance should be different when I reverse polarity on
ohm-meter (it should be one value for solenoid wire resistance, and
less for diode - huuh I hope you understand what I am trying to say,
English is not my native language). It is not. It's the same both ways.
