So my granddaughter accidentally stuck the key in the charge port! Yikes!
Fortunately, all is well. It was just a quick short & so far everything seems to work correctly. The fuses in the modules did not blow. The sudden shower of sparks scared the bejesus out of her though.
I had just unplugged the charger & as I was laying the charger aside she stuck the key in before I closed the door on the charge port.
It's a port like on a laptop, 5.1mm or so & it's on the dash about 5 inches to the right of the key switch. Bad design on my part.
You know what they say about hindsight....
Anyways, rather than move it right now, I thought if I put a diode in the line to prevent that from ever being able to happen again.
All I have on hand are 4007 & 4002 diodes. The 4002 is a little more robust than the 4007.
Which one should I use?
I don't know much about diodes but the larger 4002 is from the charge port of a cordless drill that I think was 18v so it should probably handle it.
My charger is 18v 2amp that I got with the batteries from mighty Max.
Thanks. Jim

Re: Diode in charge port circuit
Yes wired, that is what happened. It is fused. It was just a quick, merely brushing the key across the terminals in the charge port. Perhaps just fast enough to not blow the fuse??
I'll read those links you provided. Thanks.
It may be covered in those articles you linked to but I was thinking, which is dangerous sometimes, if this charger is the voltage sensing kind, my idea wouldn't work anyways as the charger would not be able to detect the voltage at the charge port, correct?
I'll read through what you've provided & see where I'm at after that.
Thanks again. Jim.

Re: Diode in charge port circuit
I have to admit, that is quite complicated. I think my brain is kind of mushy now after skimming over that second link.
Maybe I'll just move the charge port to a safe location where no one can put the key or anything else in it that is not supposed to be in there.
I thought the diode would just simply block the current & prevent a short if the key was inserted in the charge port again. I didn't realize the complexity of those little guys.
I will definitely have to read through all of that info when I have the time to sit down & absorb it all. Like, when its quiet. Lol.
Thanks again wired.
