Its a Micom-2, and I can't find any manuals anywhere. Basically their are three wires, Green, Black, and Red. The Black is sandwiched between the Green and Red and since the black doesn't have a fuse attached, I'm led to believe its a ground. The other two wires do have a fuse attached.

I blew the fuse in the Green wire so I can't really test anymore, but if the Red and Green wires are attached to the positive terminal, and the black(gnd) to the negative terminal, will the damn radio power on?

If only Motorola made manuals easy to find on the internet...

Also, when attaching two VHF radios to a single power supply, it doesn't matter the order the radio wires are connected to the PSU, does it?

I went by the manual you posted and it seems to make sense, however I managed to get my hands on the wrong fuse again. Which leads to my next question:

For example, if the power supply is a 20amp model, and the radio has a 125W peak Tx power, I'll need a 20amp, 125W fuse, correct?

Sorry again for all the nooby questions, you all are entirely too helpful :p

u will just need a fuse that will handle 20 amps or how many amps the radio draws at full power.
with a quick look, my base rig has fuse that matches max TX current draw. (which coincidently happends to be 20 amps.)

could be that the fuse blows because the rig draws more amps than the power pak can suply (dont know micom summising that rig hooked to a pow suply)
