I've been beating my head against the wall trying to get my M1008 volt meter to work. I took it to work and attached it to a power supply and it seemed like it was working, but when I attached it to the truck it didn't. So I took it off and traced all the wires around and stuff... well, turns out there's always 25-30 volts at the volt meter connector. So I hooked up the volt meter and it worked... I put the dash all back together and then the next day it stopped working again.
So at that point I was totally confised, but figured the volt meter was intermittent. I saw one on E-bay and bought that, but it doesn't work either, even though there is always voltage on the connector.
On the back of the volt meter there are 3 lugs, the wires are connected to two of them. Tonight I discovered that if I connect 24V across ground and the unused 3rd lug that it goes off the scale +voltage. I probed around some more and also see that there is about 175 ohms to ground from that connector.
I wonder if this meter is really for some other voltage range (12 volts possibly), but they divide the 28 volt voltage down to get into that range. There is a white thing between the the 2 possible lugs, I wonder if it's a resistor to divide the voltage and it's burned out?
That's my long story. My question is, does anyone know how these things are supposed to work? Or, if someone has a functioning CUCV voltmeter handy, would you mind measuring the resistance between the two lugs?
I'm going to cut and paste this to Steel Soldiers forum to, so if you hang out there you'll see it twice.
