Hi all,
Can any one help me please?
Basically, when changing the battery on my MPU4 board, i must have bridged a circuit, because on restarting machine, there was a small puff of smoke from the top left hand side of the board and everything went dead!

I have just bought a replacement (tested with new battery) MPU4 board, fitted it and it seems everything is now working except the alphanumeric display!

On consulting my workshop guide for my machine, it shows a plug in section (bottom right hand side) on the board designated to supply the alpha display, now this is the puzzling bit, when I removed my old board originally, I listed all the plugs clockwise round the board, and a). I have no record or recollection of there ever being a connection plug there, although to be certain, i have searched inside the cabinet for a unconnected plug to fit it with no success.
So, would it have been possible for the alpha connection to be plugged in elsewhere and never in that designated point on the MPU board and still work, in which case, any idea what I may have to replace/do to get it working again.
Thanks for ploughing your way through this, and thanks for any advice given,

regards,
martyn

Thanks cardie 1 for your quick reply:)
OK, are they easy to source/change?
and, can I assume that the alpha designated slot on the MPU board was never used and the alpha was plugged into somehere else?

cheers,

Used these before in the past and had no problems with them. Failing that you could try Ebay.

I used them a few years back for some IMPACT spares, and they sent a wrong part - so I emailled them repeatedly over a couple of weeks, and in the end I gave up.

Pretty sure that when I phoned them, I didn't get an answer either.

Mind you that was a few years ago, hopefully they have improved.

im not 100 percent familiar on mpu4 boards but im pretty sure it would be a direct connection from the alpha to the board .... they are simple to replace but im not too sure on the price so i would best keep an eye out on ebay
