wiring diagram/pic

hi all, does anyone have a wiring diagram preferably with picture for the plug on the end of a DD coil the end that plugs into the control box of 4500, many thanks, regards, gazza

Gazza i found this a while ago but it seems the PDF link is now missing, prehaps alchemist could repost this info.

thanks for that John, yep PDf didnt work, i know i saw a wiring diagram but cant remember where !!! regards, gazza

You have one PM'ed to you over at AGP delapan!

Delapan,
Wish I could help you, have the connections textered onto one of our caravans at our lease, thought I had the details on my puta but can't find it.

No doubt you will get the info from our members.

Cheers

Hi guys,

That diagram that Strayer posted is correct, but make sure that pins 1 and 5 are bridged on the coil plug. This helps with the high current pulses and will make the plug more wriggle resistant, ie less noise when the plug is wriggled.

thanks for the link stayyerAU very handy for all of us in here

hi mick is 1 and 5 bridged on mono or DD wiring ?? many thanks to all, for the info i needed, regards, gazza
ps it was bridged on 1 & 5 and 4 & 3 as it was. (DD wiring)

Hi Gazza,

1 and 5 should be bridged on both DD and mono coil plugs.

Cheers Mick

Good to see you giving some good advice on other forums Mick.

hi guys thanks for all that info, have got the job done, for the DD, the heavier centre wire (in clear/white cable shielding) is the TX, goes to pin 4, the shielding wire from that cable goes to pin 5, the black wire (thin centre wire of other cable) is the RX goes to pin 2 and the shielding from that cable goes to pin 1, both 1 and 5 have a heave copper bridge between them( so that the sheilding from both cales is bridged together) and 3 and 4 also have a heavy copper bridge between them, and 1 and 5 are bridged in both DD and Mono coils. On the Mono 2, 3 and 4 are bridged, with 4 being the TX/RX heavy centre wire (clear/white shielding?) and 1 being the shielding and bridged between 1 and 5, hope that all makes sense, many thanks, regards, gazza

Let us know how well the old DD N/F works delapan!

yep will let uu know how it goes, went to get a new plug from jaycar in horsham yesterday, but they were gone (owner retired) so hopefully the one on it is ok, a big DD on 4500 !!! just a theory mine !! regards, gazza

Use the old one, mate. The Jaycar ones are not good enough.
The original had gold plated contacts, so If you can reuse it. ..

How would one go about wiring the coil chassis plug from PCB to coil plug. Currently my F1A4 is wired up, Tx Red+Blue 2-3-4, and Rx Black+Yellow 1-5

How would i go about re-wiring the plug, (with a toggle switch) I'm guess to support DD coils (not that i plan to use them, but the option would be nice)

If anyone could post a diagram, or something. would be much appreciated.

On all the SD, GP & GPX Minelab machines there is no switch, as the internals of the detector know if it is a Mono or DD coil which is attached.

Your F1A4 may be different, I have no idea as have never used one, why not ask the people who mod these machines.
