Batboard

Well, I am 95% sure I have solved my own problem. Just got this Maxtrac 300 today - 5 PIN version. Measured transmit out - good! No audio, but I get the "busy" light, thus pretty sure it is receiving OK.

So I took it apart - the internal speaker has never been soldered to!!!!!

I can't be the first gut to run across this. Obviously, the previous owner used the external speaker option (out the 5 pin rear connector).

So here is my thinking - very near the 5 pin circuit board connection, there is a two-conductor (white) socket that is empty.

I'll bet that is the internal speaker connection - right?

Yep. If you can find the mating plug. Or you can tag wires on the five pin plug from inside the housing.

Yup - indeed! That was it!

I jury-rigged a connection to that white two-pin socket. Internal speaker works great!

Now looking for the real 2 conductor female connector.

Thanks!

Look at Molex catalog first then AMP (Tyco), they seem to be M's favorite connector vendors.

Look in some old computers, the sometimes they use the same two pin connector/ cable in them.

I could probably gut one out of some of these old Maxtracs we took out of service and mail you one if you can't find one.
