Do you get plus and minus 4 volts
Mine has never done a start up beep. I get a bit of chatter without a coil but others get nothing.

My board Just silent, where to check -4v, +4v?

From memory one side of C27 is positive the other minus when compared to battery minus


be careful with the audio and TX as both use minus not earth.

I have 8v on c27+, 0v on c27- ....c27 is direct track of batt and 7808

For audio stage, what transistor is used? If there is BC517, must be turned for 180 degree.

Im using mpsa13

You are correct. Its been awhile since I visited my IDX

Ground is the outer track of the board not battery negative.


Have you tried a coil.

[ripsdevala]

Yes i do, but no no sign of life....
Im sure this is just like others mistake...short, dead parts or bad soldering, but i cant see it.

....And my boy messing it up with spray paint

You could check the Wave on the TX with a coil connected


Golfnut did give some test points here http://www.geotech1.com/forums/showt...658#post181658

Let me try that

[BKY1337]

Can i use this vdi for my TGSL?
Or does a vdi for TGSL exist?

[blobber]

Yes you can use this vdi, but this kind of vdi detects only on your half distance.

Which kind does?
