Fried the MOSFET doing stuff I shouldn't have been doing. Works like a champ again.
Porter cable? Howd you diagnose ?
Fixing your own stuff is satisfying. Good work!
It's a Makita, the white series comes with smaller batteries I think.
I have an electronics background and a hunch told me the FET was bad, it's kind of where the rubber meets the road.
A quick test with a meter confirmed this.
Thanks, it is always nice to figure stuff out
Ah. Cool! Looked light gray, which is why I assumed pc.
Looks like you've been watching a bunch of AvE videos. Way to go on the fix, I don't think I would have attempted that repair.
AvE is the man.
Most of my drive to fix things came from not having money to replace them in the past. I mean, I still don't have the money to replace things, but I didn't in the past either.
Nice fix! What does "FET" stand for?
Field effect transistor
What is a MOSFET and how does one go about repairing it?
Bought a new one at digikey and soldered it in.
Edit- in the picture, I have a screwdriver pointing to it. It's basically an electronic switch.
Now that I know what FET is and what it does ( I just googled it) I wonder how many drills I have thrown out because of that transistor.
Let me guess, too much load while holding it a less than full speed putting the FET in the linear region (instead of saturation) where you have both decent Vds and a fair amount of Ids?
Aww now you're just showing off.
Oh there was lots of Ids, that's for sure.
Starter went out on the mower. The Makita started it up two weeks ago fine, but it gave up last weekend.
Doh! (said in my best Homer Simpson voice).
