Heckfire, Huck! 30v's confounded my MS
4 Attachment(s)
So after having no voltage regulator via 01+ alternator I managed to send 30 volts thru my car. Causing this:
Attachment 198125 Attachment 198126 Attachment 198127 Attachment 198128 Left a nice black spot to show me how bad I am. Burned and crack two transistors :( Is this fixable? It seems to be but just want an experience eye to tell me yay or nay. |
Totally fixable. How easy it will be will depend on whether or not you killed any surface mount capacitors in the process.
Also -> Who has to thumbs and called that shit like a pro? <--This guy ;). |
You don't need the one labeled MICA underneath it. But it's a tip125.
the 5V voltage regulator can be picked up at radio shack and replaced...hopefully that's the only thing that fried. |

Hopefully the track didnt lift

so the 5v is the one that you can barely see?
what is the tip125 used for? The two TIP125s are part of the PWM damping circuit, which are used only when you are running low-impedance injectors. |
Oh I see that I fried 3 transistors. That 5v, the most left-most one that Joe said and the two tip125s near where it says MICA. Im going to replace all of them for sure though.
The track doesnt look to be lifted or swollen in any way as well. Another thing, when I plugged a plug to check spark, when I turn the key over it sparked, but wouldn't spark when I was cranking. Is that because the 5v is fried? |
it'll spark with power on. but it's now not seeing your CAS input. If the insulators underneath the TIP125s failed and the body is making contact to the heatsink it will fail to operate...plus it's not getting VCC power to most things from the 5v reg that blew.

hope you didn't fry the processor!

The CPU, ironically, is not the most expensive component in that device. DIY sells 'em for $18.
What are the chances the processor and other important components went out as well? I've seen some pretty worn down processors from overclocking but this is a totally different ballgame lol. |
I've had two boxes in my hand that had caught on fire...only a few select spark circuit components were bad. everything else was fine! Looked a LOT worse than yours.

WOW looks like the Mega Squirt is pretty sturdy!!!!!!

It's possible you may have fried D12 or MOV1 as well. But I have fixed ECUs with worse damage than what I can see in that picture.

Are those transistors as well? If so which ones are they and can I buy them from somewhere? |
D12 is a diode. MOV1 is that big flat disc thing.
|
Sorry about the bad news. I do have one question though. Why were you running the 01 alternator? Is there a perceived benefit to running it or was it just what you had laying around?
