NEW MOTOR DOA??

[MikeinBaja]

I think I understand what you guys are talking about - I have a good voltmeter. The voltage at the sat-in fitting should be 13 or 18 V DC.

I assume with the receiver powered on I just put the + probe in the center and the - on the threads for ground?

Yes, that is right Mike, but it is better to fabricate some sort of "TAP" so that you can measure the voltage and the curent wen the load is connected (the motor and the LNBF). You have to create something that allows you to insert your meter and read the current and voltge while under a "LOAD" condition. If you test this voltage at the end of the cable in an open circuit condition, you can gain some good information, but it won't tell you the true story of what is going on. You will be missing the load on the circuit and that will alter your test readings. You will have to reseach how to insert a meter on your cabe while the load (motor and LNB) is applied.

Let's see how your new motor and LNBF respond first.

Thanks. I see what you are saying about testing under both loaded and unloaded conditions. As a start, I'll check the unloaded tomorrow.

Need to do some research on building a "tap" - looks like it's time to play JR engineer.

Mike,

Take a look at some of these products. http://www.pomonaelectronics.com/index.php These are the sort of items that I used to make a tap with. Most of the items shown here are the "push and twist" BNC connectors and not the screw on F-type, but you will get the idea and can look for related products. I got my supply of screw-on connectors from a box of salvage equipment at work. Since I didn't purchase them from a shop like Rat Shack, I don't know part numbers or prices, but Pomona Electronics is the best place to start looking. You can buy these products through Mouser, Grainger, Digi-Key, Allied Electronics, Techni-Tool and other suppliers.

Short update: replacement motor arrived - roughed out the install yesterday afternoon - It's alive!
