Anyone have a ITW DT-830D Voltmeter? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys!

I was busy installing a oven for a friend tonight, when I went to test it with my volt meter, I accidentally set my meter to DCA instead of ACV, and fried a couple of resistors real good inside.

Basically, I need someone who has the same meter as me to open it up, and help me identify the roasted components, they got burnt to a crisp, and just fell apart when I tried to remove them. There are 10 components that I've found not to be working in total, and just need you to take a look at the wiring pinout / pictures I've supplied, and give me the color coded bars / close up pics of each if that isn't too much trouble

These are cheap testers, but I've had this one for a fair while, and its been pretty good to me. I'd rather fix it then get some new fangled one that doesn't work as well, lol

Anyways, here is a pic of the fried components, where they are located on the board, and a numbered pinout I drew up. I've probally got all of the components I need, just need to find out what the charred remains are, lol

i'm sure we something like that around here...not that i know where it is or what it is for

The Diode should have something printed on it.

I would say #9 looks like a capacitor and #8 is a transistor of some sort ( if that's three legs and not a shadow). I would go spend $35 and buy one that's close to the one in the picture and give that one a proper burial. I have an analog Radio Shack meter that's about 30 yrs. old that somebody did the same thing to but everything still works except the current scales. Good luck.

Yeah, I reconize the different components. I guess I shoulda mentioned that I pulled a few good components as well. There are 7 non-working resistors there, none of which I can identify. They all got burnt to a crisp, and the markings on them are gone as such. I'm sure I've already got the resistors I need, I just need to find someone with the same multimeter as mine, so they can tell me which are which. My father has one similar, but when I popped it open, it wound up being a totally different chipboard inside.

use the risitor color code. BBROYGBVGW. google it. its easy! But I would just but another one. most new ones will not blow up like that if you hook them up wrong.

your best bet is to save the aggrevation and fighting and buy a new one. that silicon board looks cooked too

Why not just contact the manufacturer and ask them for a schematic?

That's what I was thinking. Since it's not a gel packed board, it "is" repairable. Email them and get a schematic, or at least a parts list....
