Not understanding - 12TM? Thanks

I tried to set the engine RPM the other day using my Fluke set to frequency. Seemed like I was really running the RPM up there trying to get 60 Hz power out of it. Just seemed to my ears that the motor was running faster than 1800 RPM and I was only at ~48 Hz. So I quit and ordered a laser...

Ok, great info again. Wasn't aware that wet stacking took that long. Now that I have the temp gauge working and a tube fed oil pressure gauge, I feel more comfortable running it and won't be so nervous about letting it get hot. Will do on the radiator. Is the cap something I should find in...

Some progress, some stagnation: Got the new gaskets for the thermostat and bottom of the radiator punched out and installed. Seems to have fixed all my leaks. I say "seems" because I have not run it long enough to get it really hot so not much pressure on the system yet. Got the temp gauge...

I thought everyone knew that one. Candy thermometer is the shiz!!! As soon as everyone clears out of the kitchen, I'm gonna cook up some good ole brass temp sending unit with that same candy thermometer. Yummmm! Need to get a curve for it. Did the oil pressure sensor earlier with a...

Yesterday I cleaned up radiator and thermostat fittings and painted them in the hope that it would slow down the corrosion that was going on for years. Going to make new gaskets for all of it tomorrow and put it back together to see if it still leaks. I also tested the thermostat in a pot of...

Does anyone know if the current sensing transformers are of the 1 amp or 5 amp output variety? Trying to figure out which controller to buy.

Understood. the way I understand this - and I am BY FAR NOT an EXPERT on this stuff, but anyway, the VR ramps up the voltage on the field to increase voltage generated. The more it ramps up the field voltage, the more the power dissipated at the field and current go up. Since this thing...

OK, I got you. It's rated for 4 amps at 63 VDC - which is just another way of saying 252 Watts. For the 64-68 Watts at 32 VDC I calculated, it's still 4 Amps of current. Just at 32V. I imagine that if the voltage increases, the R doesn't change so the current can only drop a little as the...

Not following - can you explain a little?

Gotcha. Looking at the specs on the Basler AVC they used / I'm using, I've got a budget of 252 Watts (4 Amps at 63 VDC) on the field supply circuit. I'm going by the fact that 24 volts from the Delco made 90ish volts on the MEP and your 32 volt number for full 120 VAC. I cleaned up the...

Ok, that makes sense. I looked up the ADVR-054. Nice piece. But it still has a minimum 15 ohm field resistance spec. So what do you have between the ADVR's F+ and the MEP's F1 wire? That's where I keep getting stuck. I'd love to eliminate those resistors on mine but I'm pretty sure that...

After talking to the guy at the alternator shop, I've kind of decided a direction to go. He said the alternator was a 24V model but that really doesn't mean anything without a 24 volt regulator. It just has denser windings so it can put out more. So basically, it'll put out, to a point, what...

Thank you for taking the time to post all that great info. I will dig into all that. Does the 56 ohm resistor generate a lot of heat? The little that I played with shoving 24V thru the 6 ohm resistor on this one, that thing got pretty hot. And that was after only a minute or so. Guess it...

Usually with that type connector, there is an extractor tool to push them out. I had one of my suppliers looking for pins and an extraction tool. Don't exist so I just went with the solder type. Since I don't have near 37 wires anymore, I could have gone with a different connector but decided...

I can't tell - not very good with the TMs yet. I got the solder type coming. I tried to get pins and an extractor for that plug. No luck and was told it was a weather proof connector and the pins were not extractable. Matters not as long as I have some way to clean it up. I bet half the...

BTW, found out that the particular connector they used to the control panel (37 pin) is a rubberized version and you cannot extract the pins. However, the same plug is made in a few different versions. They have letter designations. I think the type used OEM is an A type. Another type had...

Was able to barely read the tag on the Delco that was painted over. Has 24 V stamped on it along with some other stuff. It's at the alternator shop now.

Just checked. The field measures 2.3 ohms from F1 to F2. Thru the resistor, the Delco is seeing a little over 9 ohms.

From the TM: Equipment Test of Field Flash Circuit Assuming the exciter stator winding resistance is correct (within 1 to 4 ohms) I'm starting to see why they put the Delco in there - no one makes an AVR that will handle 4 ohms much less 2. Think I'll bring in the Delco in the morning. And...
