I have two Max Trac 100 radio's.

Radio #1 and #2: I understand that the built-in speaker is not wired on these radio's and would like to know which of the 5-pin connector "pins" that I can connect to the internal speaker ? With the cover off, the white 5-pin internal connector is towards me and to my left. I'm guessing the first and last pins but would like to know for sure.

Radio #1: No lights lite on the front panel. I believe this radio may have been accidently connected with reverse polarity to a power supply. Is there no protection circuit in these radio's and is it "toast".
THANKS

Concerning the speakers, they should be in there and it is common to pull off the wires when used with an external speaker. Take the head off and see if the connectors are laying in there, push right back on the speaker terminals. A connector pinout should be available on the main portion of the site.

Hello:
On radio number 1 if u did hook power up reversed polarity or was wired for ignition control the green pico fuse on logic bd where it says cut open for ignition sense could be bad and needs replaced.
Believe its component ju801 on schematic but parts calls it a fu801 and its a 1 amp rating.
Its back near the speaker j10 plug connector and j7 plug connector for the pa amp connector.
Also in the inside of the finned pa there is a power protection component in my manual for a 40 watt uhf pa labeled as CR2770 near the J2 power connector on the radio that you normally plug the power cord into.
This CR2770 could be damaged and if it is they normally look burnt or even blow open.
It can be blown open and if logic bd fuse is good radio should power up but if shorted then radio will be dead.
Id recommend replacing the CR2770 for future protection if it is bad even though radio will run without it.
In a 25 watt vhf pa its labeled CR2370 and in a 45 watt vhf pa its labeled CR2470 In a 25 watt UHF pa its labeled CR2670 and in a 40 watt UHF pa its labeled CR2770 but all located in the insides of the rear finned pa near the J2 power connector .
In a 60 watt lo band its labeled CR2170.

On radio number 2 check to see if speaker wires are plugged into J10 conector on logic bd and or if unconnected at speaker as mentioned above.
I have seen where the speaker wires and its plug were completely removed so you might need to solder it back in to complete audio path.
