Yes, I gave it a try, as I do have an inline fuse hooked up, and I assume by short pin 2 &3, you mean leave everything as is and place a jumper from 2-3. If so that does nothing. Or do I need to remove pins from circuit board and hook them together. I should also mention that the light work like this..... light 1 comes on.....then light 2 is added, then light 3 is added to 1 & 2, so the last of the sequence, all lights are on. This is the point I wish to have constantly. It does not go 1 only, then 2 only, then 3 only.
I am travelling for work the next few days, and when I get back I will borrow my fathers meter and see if I get any better readings.
Yeah. I understand the mode you have and the mode you would like...
The tricky part is making it do what you want it to with the limited information we have thus far. English documentation and expected readings would be lovely!
Anyway, here is the pin layout:
With the meter set to resistance, you should read the following:
- Power Wire <> Pin1 "VDD" = 0Ω, or a very small resistance.
- Power Wire <> Pin2 "GO" = 0Ω, or a very small resistance.
- Power Wire <> Pin3 "ALLON" = 0L, or very large resistance.
- Power Wire <> Pin7 "MODE" = <Unknown>
- Power Wire <> Pin9 "FLASH" = 0L, or very large resistance.
- Ground Wire <> Pin8 "VSS" = 0Ω, or a very small resistance.
- Ground Wire <> Pin2 "GO" = 8KΩ, or a large resistance.
- Ground Wire <> Pin3 "ALLON" = 8KΩ, or a large resistance.
- Ground Wire <> Pin7 "MODE" = 8KΩ, or a large resistance.
- Ground Wire <> Pin9 "FLASH" = 8KΩ, or a large resistance.
You may need to swap which probe you leave on the power wire to get these readings depending on the placement of the Diode in the assembly.
Additionally, you *can* do voltage measurements while the device is powered on.
With the black lead on the Ground Wire, you can poke and prod with the red lead.
Pin1 "VDD" = 12V or close
Pin2 "GO" = 12V or close
Pin3 "ALLON" = 0V
Pin7 "MODE" = <Unknown>
Pin8 "VSS" = 0V
Pin9 "FLASH" = 0V
Pin3 "ALLON' must be set to 'high' in order for this to do what you want.
I've found another datasheet that states that as long as 'ALLON' is high, then the other pins don't matter. Hopefully this is true. Additionally, Pin2 "GO" appears to be required, but I've translated that the device will still 'flash' if all the input pins are left empty.
It's not fun from a research side of things.
Based on the measurements you gave me, I can only assume that the IC/board may have some kind of film or coating on it, or that your meter/probes are defective.
I'm also operating on the assumption that Pin3 "GO" is connected to VCC, and suggested shorting pins 2 and 3 together because it would be easy (they are side-by-side)
You may need to jump pin1, to pin3, and if you can make sure it's connected and nothing changes, then it would appear the table I found in the other datasheet is false, and you will need to disconnect pins 2, 7, and 9 from power. (If they are connected... trying to find out with measurements)
