Need Help With MCS2000 900Mhz

Post by RoGo 1 »

I have a 900Mhz MCS2000 with the dreaded "ERROR 01/90". I understand with the right software a new codeplug can be forced into it to bring it back. Can someone out there help me with this? Please PM me if you can help. I can ship the radio to you. Thanks!

Actually, fail 01/90 is a hardware failure, not a codeplug error. It basically means the front control head is getting power, but it cannot "talk" to the main radio board. It's seen commonly in remote installations where something goes wrong with the remote interconnect cable, but also happens with dash mount configurations too.
No trees were harmed in the posting of this message...however an extraordinarily large number of electrons were horribly inconvenienced.

I think the MCS2000's also have a reputation for soldering problems, especially around voltage regulators. You might try looking for a loose component. Someone mentioned before that they opened one of these radio's and a voltage regulator fell right out in his hands.

What happened was the radio was working perfectly and the Mic plug popped out. So I reached down and plugged the Mic back in. Then the radio went into a reset and displayed the error. Now I cannot read or write to it. I know now that I should of powered it off, but it was a quick reflex.

you can probablly still read the radio if you do it from the 25 pin on the bottom and not the mic jack.

Programming via the MCS2000 accessory connector on the bottom of the radio is a good idea.
If you can make the connector yourself using the Bat Labs pin out illustration or get someone
to make it for you, that would be a big help on this and future MCS2000s. That cable is yet
another item on which you don't want to pay the Motorola price.

Programming through the mic connector is often a problem.

I believe that the MCS2000 section in Bat Labs explains the frequent detaching of the
regulator from the board and provides information on resoldering it back in place. They
say that the big concern is to not overheat the board and to use prudent soldering measures.

That nice big LCD readout is very attractive, but that radio, especially the older models, is
often problematic, a polite expression for this radio's temperament.
