Navico RT6500S

[Rustyknight]

Having had years of trouble free use from my Navico VHF, it has at long last decided to stop transmitting. I've traced the fault to some broken wires in the microphone lead...... the wires having parted company from the soldered pins in the microphone 6 pin socket.

Six different coloured wires, six pins numbered from 1 to 6..... but with nothing in the manual saying which wire attaches to which pin.

If anyone knows, I'd be obliged if they can share the info!

Simrad took over Navico a few years ago, so there may be someone within Simrad who worked at Navico. Worth a phone call to find out.

Long shot...

I wonder whether the wiring on the other side of the connection is similarly colour-coded? Might be an easy way to solve the problem.

Thanks for that Phil. I've found a website for Simrad (it seems they're part of B&G) with an e-mail addy for customer support.

Re: Long shot...

I took the casing apart, but the connections go straight into a printed circuit board /forums/images/graemlins/confused.gif

iff you get stuck, iv'e recently fitted a new mic to one.. (i think).. need to check the numbers.

i'll have a look tommorrow morning, pm me if you don't get any joy.

Curiously, although the lead is made up of 6 different coloured wires + what appears to be a screen, only 4 of them are connected in the fist mike end.... the others appear to be spare!

Blue and white to the PTT switch, red and possibly the screen to the microphone itself.

I suppose that cuts down the number of possible mistakes at the other end! /forums/images/graemlins/blush.gif

got a strange feeling that the reason for that is, the possiblility of fitting a telephone style handset...

like i said i cant remember which one it was.. i seem to have quite a collection of VHF's lurking round...

 

[aztec]

just checked.... ain't i good to you??

1=sheild
2=green
3=orange
4=white
5=red
6=black

green and white seem to go to the speaker on the telephone handset.

Steve,

Many thanks for that. I'll be down in Poole again tomorrow with my soldering iron and see what happens!

I've a Navico RT6500 VHF and while cleaning the channel change button contacts with the set split in two, managed to (a) disconnect (break away) the black wire from behind the mic connector, and (b) also break what appears to be a resistor on the back of the mic connector. Would anybody be able to tell me the pin-out colours from the mic connector inside the set (or maybe post some photos of this, ideally identifying the resistor colour bands)?
